Control measures of cucumber wilt
First, strengthen seedling management, nurturing strong seedlings, and timely prevention and control of pests and diseases.
Second, to strengthen the greenhouse warming and warming work, pay attention to insulation when the cold flow, and pay attention to this time do not water, so as not to reduce the soil temperature.
Third, reduce the use of fast-acting fertilizers, apply more organic fertilizer, and the top dressing, top dressing can be sprayed with highly efficient phytoremediation, composite potassium dihydrogen phosphate, spray Po, AAA and other foliage fertilizer.
Fourth, after the rainy weather, the sheds should expel the grasshoppers, cover the sides and cover the leaves, spray the leaves with warm water of about 20°C, remove the old leaves in time, and reduce the transpiration. After the seedlings return to normal growth, they can all be drafted during the day. Even if it is a cloudy day, drafting must be done as far as possible so that the seedlings will see more scattered light. However, at night, it is still necessary to cover two layers of protective film to do the insulation work.
5. Water, fertilize and spray pesticides in time after sunny days to promote seedling emergence and disease prevention and control.
Sixth, cucumber planting 15-20 days before planting foot muddy water, if the living soil layer is too deep, after watering, we need to level the surface again, so that the soil reaches deep, transparent, fine, flat, solid standards. Watering is suitable for drip irrigation to avoid flooding and maintain good air permeability.
