Management techniques and methods of various vegetables in hot and rainy weather

In August, after the continuous high temperature, continuous rain for many days, the vegetable field management technology requirements are high. Special efforts should be made to strengthen drought resistance and flood prevention in the vegetable field, topdressing, weeding and weeding, flower and fruit protection, and pest control. Vegetable management techniques and methods are introduced as follows:

1. Properly control the fertilizer and water in the early stage of tomato, and follow the fertilizer in time after fruit setting, and pay attention to the prevention and treatment of early blight, cotton rot, virus disease, aphid and cotton bollworm. Eggplant regeneration Eggplant should strengthen the management of fertilizer and water, keep moist, and focus on strengthening the prevention and control of verticillium wilt, cotton rot, and brown streak.

2. For autumn eggplants or late-fallen eggplants, fertilizer and water management must be strengthened about 10 days after planting. Water is drenched with fertilizer during drought, and drained immediately after heavy rain.

3. The focus of Qiuyan cucumber is to prevent diseases and insect pests. For 2 to 3 true leaves, spray with medicine every 7 days to prevent downy mildew. For 3 to 4 true leaves, spray 40% ethephon (concentration: 100 mg / L) twice, once every 2 days.

4. The key to zucchini is to prevent the occurrence of viral diseases. At the early stage of growth, attention should be paid to the prevention of aphids. After the rainstorm, clear the ditch in time and add fertilizer. Field tillage, especially after watering, fertilizing, and raining, should be conducted once in time.

5. Pumpkins should be cut from the end of August to the beginning of September. Choose 1 to 2 strong side vines at the base, and apply 30% concentrated manure and animal manure to keep the soil moist.

6. Winter melon climbing the ground and winter melon can be combined with drought resistance in the middle growth period, and the topdressing concentration is 30% of the rotten human and animal dung 3 times. Cultivate winter melon, use infiltration ditch irrigation to resist drought, but do not flood irrigation, keep the surface slightly wet. The surface of the melon covers the sun, and the bottom of the melon protects against rot and insect damage.

7. Water the gourd when it is hot and dry, and take the "dark water" method. It is necessary to clear the ditch and drain the water in time after the rain. It is best to irrigate the ground with well water or deep river water, so as to prevent the mellow leaves from wilting after rain and affect fertility. Topdressing and watering should be carried out in a timely manner. After heavy rains, timely ploughing should be carried out to prevent diseases and insect pests.

8. Cowpeas are mainly planted with squatting seedlings before flowering and pod formation. After the pod formation, the soil is kept moist. Picking is carried out 2 to 3 times during the harvest period and topdressing is applied once. The main vine is topping in time, timely removing the lower yellow old leaves, and paying attention to the prevention and treatment of rust.

9. Chinese cabbages in summer and early autumn pay special attention to the occurrence of diseases such as soft rot and Spodoptera litura. After planting and before the trees are alive, water the drought-resistant seedlings in the morning and evening. Before and after the rosette period, water is often used to keep the soil moist. Beginning, pay attention to watering and drought resistance.

10 Early autumn radish keeps the soil moist, and water it in time in case of drought. Special attention should be paid to the prevention and control of early diseases and insect pests. After emergence, the main control is to prevent jumping beetle, and to prevent aphids after emergence. In late August, spray 90% trichlorfon 800 times solution and 80% ethyl phosphine aluminum 400 times solution to prevent other pests and downy mildew.

11, celery pay attention to the use of shade nets or straw curtains to set up shade sheds in time to strengthen fertilizer and watering to keep the soil moist. Control aphids, soft rot and leaf spot in time.
