There is a very small detail in the vegetable management of the greenhouse, and most of the vegetable farmers do not care. Vegetable sheds need to be peeled and covered every day. It is bound to drop a lot of crushed grass from the rake, and the crushed grass is very light. It is easy to blow into the shed with the wind through the vents, and attach to the leaves and mulch of vegetables. At the same time, it affects the photosynthesis of plants and reduces the yield of vegetables. At the same time, these broken grasses often carry pathogens and are prone to coal pollution. Therefore, when the broken end of the vegetables on the vents is found, it must be promptly removed. Due to the lightness of the broken grass, the vegetables are generally shaken and the broken grass will fall to the ground. In addition, the end of mulching grass on the mulch must be cleared in time to avoid weakening the insulation of the mulch.
