① the function of poplar

"There is a little white poplar growing next to the post", which is the lyrics of the military camp song "Little White Poplar" sung by the famous singer Yan Weiwen. So what kind of tree is poplar and what is its function?

The function of poplar

1. Poplar can be widely used in ecological protection forest, three-north protection forest, agricultural and forestry protection forest and industrial timber forest.

2. Economic utilization of poplar

The use of wood is generally determined by its structural, chemical and physical and mechanical properties. There is little difference in cell wall thickness between poplar morning and evening wood and fiber, but the ash content of lignin, pentose and resin is low, the wood is white, the resin is less, it is easy to bleach and the pulping rate is high. It is an excellent raw material for papermaking, and also a good plywood and fiberboard. It can be said that the whole factory can, but in different ways.

(1) Large-diameter wood with a small head diameter of more than 26cm is mainly used as plywood material.

(2) Medium-diameter wood, with a small head diameter of about 20cm, is mainly used for pulping and papermaking.

(3) Small-diameter timber, with a small head diameter of 4- 12cm, is mainly used to produce fiberboard and particleboard. The products it produces are environmentally friendly products. It can use low-quality and cheap wood and other fiber raw materials to produce wood-based panel products with excellent performance, stable quality, wide use and high added value, instead of wood-based panels such as sawn timber and plywood, and is widely used in furniture manufacturing and interior decoration, with very broad prospects.

3. Garden application of poplar. Poplar, as a road greening, is also an excellent tree species for landscaping, which is characterized by being tall and majestic, with neat signs and fast forest formation.

4. Ecological utilization. Water source protection, soil and water conservation, air purification, etc. Poplar is a pioneer tree species in environmental restoration. Developing fast-growing poplars and building an ecological shelter forest system will surely bring "three major benefits".

② the function of Chinese milk vetch

Safflower, also known as Astragalus sinicus, is a perennial herb of Astragalus in Leguminosae. It is interplanted in late rice fields in autumn as the base fertilizer of early rice, and it is the most important winter green manure crop in rice fields in China.

Besides being used as green manure, Chinese milk vetch can also be directly used as feed or silage with high nutritional value. Fields are everywhere in spring, just like Ziyun, which is really beautiful.

In my hometown, every time after the Qingming rice seedling sowing season, we must first do a good job in seedling fields and cultivate strong seedlings. In order to have enough base fertilizer in the paddy field, every time a farmer digs a nail of palladium, he scatters a handful of cut safflower in the soil as the base fertilizer, which is called "making paddy field". Some still plough safflower in paddy fields on a large scale, and let it rot into high-quality green manure. For the bumper harvest of rice, this kind of safflower was buried in the soil and used as fertilizer soon after it came into the world.
