China has thousands of years of vegetable cultivation history and countless experiences. With these experiences, we can grow vegetables well and achieve high quality and high yield without chemical fertilizers and pesticides. Here are some practical recipes for growing vegetables.
1, a nest of sweet potatoes and a handful of ash, sweet potatoes form a lot.
As the saying goes, when plant ash is sown in the process of planting sweet potatoes, the yield of sweet potatoes is very high. Plant ash is a kind of natural potash fertilizer, which has the functions of regulating soil acid-base balance, supplementing nutrition and preventing diseases and insect pests.
2, sheep manure is home, two seasons are not embarrassing; Cow dung has become a home, and it is useless to grow anything.
The meanings of these two agricultural proverbs are easy to understand. If the base fertilizer is mainly sheep manure, the yield will increase. Moreover, if the base fertilizer is mainly cow dung, it will not increase production. The organic matter content of sheep manure is as high as 24%, and it is rich in potassium, nitrogen, phosphorus and many mineral elements. Moreover, sheep manure can loosen the soil and enhance the ability of soil to retain water and fertilizer. It can be said that sheep manure is a high-quality organic fertilizer. Cow dung is a cold fertilizer with slow fertilizer efficiency, which is not conducive to the growth of crops with short growth cycle. Vegetables are easy to fertilize after being applied to soil.
3. Adding brown sugar to yeast can take root and promote growth.
During the growth period of vegetables, you can use 1 kg brown sugar, 1 00g yeast,1kg soybean milk or expired milk, add 50 kg water, and seal and ferment for half a month, which will have sour taste. Then you can wash or water 500- 1000 Jin of water, just use it.
4. Soybean and agricultural fertilizer, yield and fertilizer.
Soybeans and bean cakes are much stronger than chemical fertilizers, which can not only increase the yield of vegetables, but also make vegetables delicious and enrich the soil. No need to apply more. You can apply 50 kilograms of bean cakes or soybeans to an acre of land every year, and the land will be more fertile year by year.
5. Rotate vegetables to increase production and prevent diseases.
Growing vegetables is most afraid of continuous cropping, that is, planting one vegetable a year on a piece of land. Continuous cropping can not only make vegetables grow well, but also lead to serious diseases, reduced production and even no harvest. So no matter what kind of vegetables you grow, you have to rotate them.
6, urea scattered on the surface, nine times out of ten are wasted.
As the saying goes, when growing vegetables, urea should not be applied to the surface, otherwise urea will be wasted. When urea is applied, it should be applied deeply, which can not only improve the conversion efficiency of urea, but also give play to the fertilizer efficiency relatively quickly; But also avoid that waste after urea is convert into absorbable nutrients, and improves the utilization rate of urea.
