1, rice Variety selection. Mainly select hybrid rice varieties (combinations) with disease resistance, high quality, balanced panicle and grain yield, such as Shennongyou 228, Yuxiang 203, Yixiangyou 2 1 15, Shenzhen Liangyou 58 14, C Liangyou Huazhan and Y Liangyou1/. Seed treatment. Before sowing, choose sunny days and dry the seeds for 3-4 days. Soak the seeds after disinfection to make them fully absorb water. The husk is transparent (you can see the rice grains). After the rice grains become soft and have no hard core, the laundry list method should be used to accelerate germination. Sowing date. The sowing date of rice in the whole region should be from the end of February to March 10. That is, planting in the east from February 26th to March 3rd, and planting in the west from March 3rd to-10. During this period, the seeds will be sown in sunny days, with a cold tail and a warm head. Cultivate strong seedlings. Film-mulching seedling raising technology with moist multi-tillers and strong seedlings is the most widely used seedling raising method in our region at present, which is suitable for two-season fields that cannot be harvested on April 20, such as rape, wheat, broad beans and other spring sowing crops. Paddy field soil preparation It is advisable to choose shallow mud and sandy land with convenient irrigation and drainage, sunny and leeward, fertile soil, barrier-free seedling growth and convenient seedling transportation as the nursery. Before the Spring Festival, according to the soil fertility of paddy fields, appropriate amount of decomposed organic fertilizer and phosphate fertilizer were applied to fertilize paddy fields. 5-7 days before sowing, shallow water rotary tillage is carried out until it becomes paste, and precipitation is reserved. Spare paddy fields should be ploughed till they are thoroughly cooked and smooth, and try not to contain impurities. Prepare paddy fields according to the ratio of paddy fields to paddy fields (1: 10 ~ 15) (prepare paddy fields according to the ratio of 1: 10 for fields that cannot be harvested on April 20th, and use fields that can be harvested in winter or before April 20th1. Make seedbeds. 3-5 days before sowing, make a seedbed in the cultivated seedling field. According to the width of 2m, the carriage should be opened. The width of the compartment is about 0.5-0.6m, the depth of the compartment is 0. 15-0.2cm, the effective seedling surface is kept at about 1.5m, and ditches are dug around the paddy field to ensure the smooth water system. The surface of the seedbed should be smooth, with the same height, without convex and concave impurities, so as to be "solid, flat, bright and straight". At the same time, half ditch water should be poured to dry the seedbed and make the bed surface knot. Precision sowing. When there is no clear water in the seedling compartment, the seedlings are accurately sown in compartments, and 750-800g hybrid rice seeds are sown in compartments per mu of field where seedlings are planted, that is, in fields that cannot be harvested before April 20th, and 750-800g hybrid rice seeds are sown in compartments per10m; In the field that can be harvested, 750-800 grams should be sown every 7-8 meters. Paddy field management. Temperature and humidity control. From sowing to seedling stage, heat preservation and moisture retention are the main measures. When the temperature in the shed exceeds 35℃, the film at the end of the arch shed should be uncovered for ventilation and cooling. If there is an intima after the vertical needle turns green, the intima should be uncovered. Uncover the film and harden the seedlings. When 1 leaves 1 center to 2 leaves 1 center, gradually uncover the film, ventilate and temper. Pay attention to replenish water once on the day of uncovering the film, and strengthen seedling hardening after the central period of two leaves of 1, uncover the film during the day and cover it at night on sunny days. Uncovering the film and hardening seedlings should first uncover both ends, then one side, and finally gradually open the greenhouse film completely. Topdressing before and after the 2.5-leaf stage of seedlings, choose 2-3 kilograms of urea per mu of rice field in the morning and evening, mix it with 200 times of water and spray it evenly to apply "weaning fertilizer", and then spray it with clear water to wash the seedlings. 3-5 days before transplanting, 750 kg of biogas slurry or decomposed manure water and 2-4 kg of urea are sprinkled on each mu of rice field, and "wedding fertilizer" is applied. Prevent diseases. When the seedlings grow to 1.5 leaves, spray 35% Likujing solution or 600 times 70% Dixon 2.0g water solution per square meter to prevent and control Likujing. 2-3 days before sowing, 30kg of 20% tricyclazole100g and imidacloprid10g are used to spray seedlings per mu of paddy field to control rice blast, aphids, thrips, etc. Field preparation and application of base fertilizer. Plow once in the field, apply farmyard manure 1000 kg per mu (or 500 kg of straw returned to the field in the first year), apply 40% rice special compound fertilizer 30-40 kg per mu (30 kg in fertile field and 40 kg in thin field), then level it with a rake to make the fertilizer fall into the mud, and then plant seedlings. Field transplanting. The wide and narrow rows are planted in the wide and narrow rows of (1 1 inch +7 inch) ×6 inch, that is, each mu11000-12000 nests, and two plants are planted in each nest; Insert the machine according to the specification of 12000 nests/mu (9×6 inches); When throwing seedlings, throw nails per mu1.2-1.4 million nests; When planting seedlings in rows, plant 6 rows (one row in the middle, 5 rows in the middle) according to 4.8-5.4 feet, and the nest spacing is 6-7 inches; Intensive cultivation (measurement) of rice is carried out according to the row spacing of 33-40 cm (1-kloc-0/.2 ft) and the hole spacing of 30-33 cm (0.9- 1 ft), and 5,000-6,000 large nests are planted per mu, and 3 nests are planted in each large nest. Field fertilizer and water management. 7- 10 days after sowing, apply 3-5 kg urea per mu as seedling fertilizer; Before the jointing stage (early June), 7- 10 kg of potassium chloride and 3-4 kg of urea were applied per mu to fertilize the jointing stage; In the first ten days of July, 2-3kg urea was applied per mu as spike fertilizer to increase grain weight. Water management is very important, and shallow water is mainly used in rice planting, tillering and seedling stage. In the first half of June, if there are too many rice seedlings (more than 300,000 seedlings per mu), we can control the seedlings by flooding deep water, or in places with good water resources, we can control the seedlings by draining the field water and drying the field. Strengthen the comprehensive prevention and control of diseases, pests and weeds. In early May, 1.5-2 kg large-grain insecticide was applied to each mu of field to control the first generation rice borer, and in early July, 1 kg large-grain insecticide was applied to each mu of field to control the second generation rice borer. At the same time, pay attention to observe and prevent rice blast.

2. corn. Corn is the king of feed and an important industrial raw material. Developing corn can promote the development of animal husbandry and industry. With the temperature rising, while doing a good job in epidemic prevention, farmers in the whole region can adopt fattening seedlings, plastic film mulching and other methods to catch up with the farming season and sow in time. Select high-quality and high-yield varieties. Corn production mainly adopts "wheat (oil)-jade-stalk" or ridge planting corn interplanting mode, and varieties with high quality, high yield, medium stalk, strong disease resistance and good adaptability should be selected. Training mode. Mainly promote the "septum planting" model. Sowing time. From the middle and late February to March, according to the current epidemic prevention and control, market demand time (peak shift) and other requirements, sowing can also be delayed or timely in batches. Planting techniques. Fat ball seedling raising. Preparation of seedbed: Choose a vegetable garden with leeward and sunny, convenient irrigation and drainage, and sandy soil as seedbed. Before sowing 10- 15 days, turn over the seedbed shallowly, ditch according to 1.8m, clean the seedbed surface with a width of 40cm and a depth of 20cm, and level the seedbed surface. Production of fertilizer dough: use 2/3 of vegetable topsoil13 of soil miscellaneous fertilizer and a small amount of calcium superphosphate, sprinkle with pig manure until it can be kneaded into dough and spread on the ground to a certain degree. Then knead into fat balls with a diameter of 6-7 cm, and insert a stick with a diameter of 2 cm in the middle to plant. Seed treatment: choose sunny days for 3-4 days before sowing. Sowing: Sow 2-3 seeds for each fertilizer ball, and cover it with fine mud after sowing, depending on whether it is sowed now. Then wet it with clean pig manure, arch the film with bamboo pieces, and then seal it around. Seedbed management: mainly temperature management. Before emergence, it is mainly to keep warm, subject to film mulching, and the temperature in the film is generally controlled at about 25℃; After emergence, the temperature is mainly controlled to prevent seedlings from burning at high temperature, and the temperature in the film is controlled at about 20℃. In the one-leaf stage, you should uncover the film and harden the seedlings, first two ends, then half, and finally all. Open both ends or one side of the carriage to cool down on sunny days. Re-apply base fertilizer. Nest-building: according to the specifications of planting 1400 nests per mu, two plants are planted per mu, and 2,800 plants are planted, that is, the nest spacing 1.4 feet, with 3 feet reserved in two rows and 2.4 feet spacing between two rows. Apply base fertilizer: apply base fertilizer in time after nesting. Use 40 kilograms of 40% corn special "bb fertilizer" per mu, and apply pig manure 1000 kilograms (that is, 2 kilograms per load of chemical fertilizer). After the base fertilizer is applied, cover the fertilizer with a small amount of soil. Transplantation in time. After applying base fertilizer 10- 15 days, directional transplanting was adopted, and each nest 1-2 fertilizer balls (two plants were planted). After transplanting, spray root fertilizer with 500 kilograms of pig manure per mu.
