Pay attention to controlling grass in orchards

Orchard grass can increase the content of organic matter in the soil, reduce soil erosion, improve soil structure, and increase fertility. However, some orchard farmers misunderstand the meaning of orchard grass and let the weeds grow in the orchard without paying attention to controlling the grass. As a result, many problems have been brought to the orchard management.

At present, most of the raw grass orchards use natural grass growing methods, which are not selective for grass species, and do not pay attention to grass control or plowing, so that weeds are serious, even in individual orchards, some weeds It grows to one or two meters, competing with the fruit trees for space and space, causing the fruit trees to be buried in the weeds. At the same time, the contradiction between weeds and fruit trees competing for fertilizer and water is outstanding. Especially in the dry season, the lack of water in fruit trees exacerbates the occurrence of drought damage, which causes the soil to compact and affect aeration, resulting in roots floating and causing shallow roots. Moreover, the season when weeds grow vigorously, not only brings inconvenience to various operations in the orchard, but also becomes a potential place for diseases and insect pests.

From this point of view, raw grass orchards should control the growth of grass and timely mow to mitigate the conflict between grass and fruit trees competing for water and fertilizer in spring and summer. It can also increase the yield of grass and increase the content of organic matter in the soil during the year. Under normal circumstances, mowing can be done 2 to 4 times a year. Orchards with good irrigation conditions can be mowed once more. If the whole garden grows grass, the cut grass will be spread on the spot, or it can be buried deep in the trench and mixed with the soil to get fertilizer.
