Strengthen vegetable field management measures

First, strengthen fertilizer and water management

Fertilization should follow the principle of “multiple application of organic fertilizer and less application of chemical fertilizer”. Fertilization should be targeted, and leafy vegetables (cabbage, celery, etc.) should be topdressed with nitrogen and calcium fertilizers, supplemented with potash fertilizer, phosphate fertilizer, and some medium and trace elements (calcium, zinc, magnesium, etc.), with a certain amount of foliage. Fertilizers (potassium dihydrogen phosphate, etc.); fruits and vegetables (watermelon, wax gourd, tomato, etc.) must be dominated by phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer, and the application of some elemental and trace element fertilizers should be increased; Potassium-based fertilizers should be the main supplement for root vegetables. Phosphate fertilizers and trace element fertilizers.

Second, strengthen field management

1. Weeding and weeding. The high temperature and rain in summer are conducive to the growth of weeds. We must often cultivating weeds and weeds, and let loose soil not be too deep so as not to damage the roots.

2. Drain in time. Watering, proper drainage, high temperature in summer, uneven rainfall, attention to watering in case of drought, water pouring in small water, and keeping dry in sight; when rainfall is heavy, it is necessary to pay attention to drainage, dig drainage ditch, and make drainage Smooth, no water, reduce disease.

3. Plants are trimmed. For scaffolding vegetables (such as cucumbers, beans, tomatoes, etc.), planting (hiccups, picking old leaves, diseased leaves) should be carried out in time to facilitate ventilation, light transmission, and increase fruit setting rate; for watermelon, pumpkin, and other man-made vegetables, Staying vines should be reasonable and the control groups should not be too large in order to enhance the disease resistance.

Third, strengthen pest control

In summer, vegetables are prone to more pests and diseases, such as wilt disease, viral disease, soft rot, downy mildew, root rot, powdery mildew, bean pods, roundworms, etc., as well as some physiological characteristics such as cracking, fruit dropping, and poor growth. Disease. Adhere to the principle of "prevention and treatment as the supplement," and strongly advocate the use of biological pesticides.
