Summer vegetable field management

Since the summer, the hot and rainy weather has gradually increased, and vegetables are highly prone to pests and diseases, making cultivation and management more difficult. Field management should be strengthened from the following aspects to achieve high quality, high yield and high efficiency.

First, strengthen fertilizer management

At present, most of the summer vegetables are in a critical period of growth, and a small part has entered the harvesting period. At this time, proper management of fertilizer and water has a great impact on the high yield, high quality and high efficiency of vegetables. Fertilization should follow the principle of “multiple application of organic fertilizer and less application of chemical fertilizer”. Fertilization should be targeted. Leafy vegetables (cabbage, celery, etc.) should be based on nitrogen fertilizer and calcium fertilizer, supplemented by potassium fertilizer, phosphate fertilizer and some medium and trace elements (calcium, zinc, magnesium, etc.), with certain foliage. Fertilizer (potassium dihydrogen phosphate, etc.); melons and fruits (watermelon, melon, tomato, etc.) should be mainly phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer, increase the application of some medium and trace element fertilizers; root vegetables are mainly potassium fertilizer, supplemented by Take phosphate fertilizer and medium and trace element fertilizer. Watering and drainage should be done properly. The summer temperature is high and the rainfall is uneven. Pay attention to strengthen watering and small water during the drought, and keep it dry. When the precipitation is large, pay attention to drainage and digging the drainage ditch. In particular, root vegetables (radish, etc.) and melons are greatly affected, and water accumulation is likely to cause problems such as scalding, rooting and rot. At the same time, after the heavy rain (in the case of good drainage), some groundwater is poured to lower the ground temperature, and watering can be combined with fertilization.

Second, strengthen field management

　　 1. Weeding. It is hot and rainy in summer and is beneficial to weed growth. Always weed and weed, do not loosen the soil, so as not to hurt the roots. Try not to use herbicides, which have a great impact on the growth of vegetables. If you choose improperly, you can even affect vegetables for more than 2 years.

　　 2. Rigging and ridges. In summer, there is a lot of rain, and drainage is the key. For ridged vegetables (such as cabbage and green onions), it is necessary to cultivate the ridges in time due to rain or watering. The vegetables that have not had ridges should be ploughed according to the actual conditions of vegetable growth. Make the drainage smooth, no water accumulation, and reduce the disease.

　　 3. Plant finishing. For scaffolding vegetables (such as cucumber, beans, tomatoes, etc.), planting should be carried out in time (snoring, picking old leaves, diseased leaves) to facilitate ventilation and light transmission, and to increase the fruit setting rate; for watermelons, pumpkins, etc. It is reasonable to keep the vines, and the control group should not be too large to enhance the disease resistance.

Third, strengthen pest control

Summer vegetables are prone to more pests and diseases, mainly buckwheat, viral diseases, soft rot, downy mildew, root rot, powdery mildew, bean wild mites, mites, etc., as well as some physiological physiology such as cracked fruit, fruit drop, poor growth, etc. Disease. Adhere to the principle of “prevention of prevention and treatment as a supplement” and strongly advocate the use of biological pesticides.
