Is it better to weed the orchard or plant grass in summer?

In production, most friends in the fruit tree planting base will clean the grass under the fruit tree for fear that others will say that he is lazy. Yes, cleaning and burning the fallen leaves and weeds of fruit trees outside the garden can reduce the occurrence of pests and diseases in the coming year. However, it wastes all the benefits of planting grass in the orchard. We can't have it both ways, can we? Yes When we understood the benefits of planting grass in the orchard, we learned how to reduce the pests and diseases in the orchard.

1. Planting grass in orchard can effectively prevent soil erosion. Planting grass in orchard can reduce soil erosion and enhance soil water conservation and drought resistance. After planting grass, dense vegetation and developed roots can effectively prevent soil erosion, thus playing an effective role in protecting soil. Especially in dry years, it can significantly reduce the fruit cracking and falling caused by the sudden change of dry humidity, and its practical and economic value is obvious.

2. Planting grass can effectively inhibit the growth of weeds, the orchard grows vigorously and can inhibit the spread of weeds. Artificial weeding and chemical weeding are basically not needed after planting grass to completely cover the orchard. Planting grass in orchard is a kind of banded grass between artificial gardens or fruit trees, mostly excellent perennial grass. This is an active, practical and effective soil management method.

3. Planting grass in orchard can actively improve soil moisture. Orchard soil in mountainous areas is often barren, which affects the healthy growth of fruit trees. Planting grass can obviously improve soil fertility, especially for leguminous vegetation. Rhizobia can fix nitrogen 10- 13 kg per mu every year, which is equivalent to applying 22-29 kg of urea. The fixed organic nitrogen can be directly absorbed by fruit trees. In addition, the rotten roots and dead leaves of grass cover are rich in nutrients and accumulate in. Or choose a lobster sauce in the orchard, collect fallen leaves and hay, mix it with soil miscellaneous fertilizer, soil or proper amount of "Fugen", add water and stir it, then seal it with soil, and after a period of fermentation, it becomes an excellent organic fertilizer. Sterilization, pest control and fattening-why not?

4. The research proves that planting grass in orchard can not only adjust the ground temperature, but also effectively improve the growth environment of fruit trees. Make the seasonal temperature change of the orchard soil surface layer smaller, and the day and night temperature change smaller, adjust the ground temperature and humidity, and improve the growth environment of fruit trees.

To sum up, the comprehensive effect of various factors can increase the inflorescence number of fruit trees, increase the fruit setting rate by about 10%, increase the color, sugar content, VC content and soluble solid content of fruits, and reduce the nitrate content.
