Soil disinfection method in strawberry field is an important technical measure to ensure strawberry production and income increase. The sunny, hot and high temperature weather in July and August is a favorable opportunity for soil disinfection in strawberry planting areas (especially in continuous cropping areas). According to the actual situation of our city, several soil disinfection methods are introduced for reference of strawberry growers.
First, use solar energy to sterilize the soil at high temperature.
Operation technology: clear the field before disinfection, and the previous field is rice. After rice is harvested, the rice stalks are chopped and returned to the field. Then apply 2000 kg of decomposed manure or 500 kg of chicken manure per mu, add cake fertilizer 100 kg and 50 kg of hydrated lime, and sprinkle in the field. After ploughing, there is a certain water layer (half a clod) in the field. Then cover it tightly with agricultural film, and disinfect the soil by using the energy generated by high temperature and decomposition of organic fertilizer in dog days. The mulching time of agricultural film should be more than 20 days, and the longer the mulching time, the better the effect. After uncovering the film, the water in the field is naturally absorbed by the soil, and then 50 kg of compound fertilizer and 50 kg of phosphate fertilizer are applied to the border.
Two, Mianlong or Rongbao (lime nitrogen) soil disinfection method
The dosage of cotton dragon agent for soil disinfection is 20 kg per mu; The dosage of Rongbao (lime nitrogen) used for soil disinfection is 40 kg per mu.
Operation technology: clean up the site, apply sufficient decomposed base fertilizer and base fertilizer, and evenly apply Mianlong or Rongbao (lime nitrogen) for soil ploughing; Or if the machine is used for ditching, Mianlong or Rongbao (lime nitrogen) can be used as the ditching line, and the surplus chemicals are evenly scattered in the field to ensure that the chemicals are evenly distributed in the soil of 15-20 cm when the machine is ditched; If the soil is too dry, you can properly water the ground to maintain a certain soil humidity; That is to say, the closed garden is covered with agricultural film for about 10 days. After uncovering the film, prepare soil or loose soil for the border surface and ventilate the border surface. At the same time, fully irrigate the garden to speed up the volatilization of chemicals. Strawberries can only be planted after 5 days to avoid damaging the seedlings.
The big nutrition of small strawberry is 1, which is a good slimming product.
Spring is an itchy season. When girls are ready to put on spring clothes, it is natural to start a new round of weight loss. At this time, strawberry can exert her magic. Strawberries and yogurt are a perfect match.
American nutritionists have found that the satiety of food is closely related to the dietary fiber content, and foods with high fiber, coarse particles and slow chewing speed have a strong satiety. Strawberry contains a lot of pectin and cellulose, which can promote gastrointestinal peristalsis and increase satiety.
2. Natural tooth whitening agent
Strawberries also rank first in the list of foods for whitening teeth. Malic acid contained in strawberries, as an astringent, can be oxidized when mixed with baking powder, which can remove the stains left on the tooth surface by coffee, red wine and cola.
3. Inner strength.
According to a new study published by the Daily Mail, anthocyanin is an antioxidant, which is contained in red, blue and purple berries and vegetables such as blueberries and strawberries, and can prevent and repair cell damage.
Studies have shown that eating more fruits and vegetables rich in anthocyanins when you are young will help reduce the risk of heart disease in the future. Anthocyanins can help improve the level of cholesterol (high-density lipoprotein cholesterol) and reduce inflammation related to heart disease.
4. Vitamin storage tank
Strawberry is rich in amino acids, fructose, sucrose, glucose, citric acid, malic acid, pectin, carotene, vitamin B 1, vitamin B2, nicotinic acid and minerals such as calcium, magnesium, phosphorus, potassium and iron. These nutrients have a good role in promoting growth and development, which is of great benefit to the elderly and children.
Foreign scholars have found that the effective components in strawberries can inhibit the growth of cancer. Does every100g strawberry contain vitamin C50? 100 mg, which is 10 times higher than that of apples and grapes. Scientific research has also confirmed that vitamin C can eliminate the relaxation and tension between cells, make the structure of brain cells firm, and make the skin delicate and elastic, which has an important impact on the development of brain and intelligence. Eating strawberries after meals can also decompose food fat, which is beneficial to digestion.
Tips for selecting strawberries Although we all know that the higher the sugar content of fruit, the better it tastes, but the sugar content is not debatable just from the appearance. So what can we do to choose fresh strawberries with sweet taste to ensure our health?
