Appropriate topdressing: In early July, it was the time of pepper coloring. Just after the rain was completed within 10 days, foliar spray fertilizer could be applied. When spraying, a new high-fat film was added to effectively improve the efficiency of fertilizer efficiency. Stop the application of nitrogen fertilizer to prevent the latter season from growing. At the same time, the base fertilizer should be applied as early as September to October, which is conducive to improving the nutrient level of the tree.
Field management: timely cultivating and weeding to promote the strong growth of the tree, pay attention to timely discharge of stagnant water after the rain, and guard against root rot.
Plastic pruning: summer pruning is generally carried out 2 to 3 times a year, mainly removing dense branches, overlapping branches, pests and branches, etc., in order to improve the ventilation and light transmission conditions of the pepper tree, improve photosynthesis, make nutrients easy to accumulate, and promote the formation of the next year. More knots of pepper. The pruning mouth should be applied in time to apply the anti-corrosion film to protect the wound from healing and isolate the pathogen.
Crop management after heavy rains
In summer, the climate is changeable, and there are often high-temperature rainstorms that attack crops. Especially in recent days, heavy rains and hail weather frequently occur. In order to minimize vegetable losses, vegetable farmers should take the following protective measures:
1. Implement Qingyuan
After the rainstorm, the leaves of the vegetable garden should be cleaned up immediately to avoid the spread of the disease, and artificial water splashing should be organized to wash off the sediment adhering to the stems and leaves, increasing the oxygen in the soil and keeping the vegetables in a normal breathing state. At the same time, the plants are corrected to reduce mutual extrusion. Timely re-cultivation of vegetable fields with serious losses, and considering re-seeding vegetable varieties with short growth period, such as water spinach and cabbage.
2. Supplement fertilizer
After the rainstorm attack, the vegetable root activity became weak, and the water absorption and fertilizer absorption capacity were both poor. At this time, the foliar fertilizer should be sprayed, and the 1% imported urea solution should be added to the leaf surface with potassium dihydrogen phosphate solution to enhance the fertilizer absorption capacity. Rejuvenate. At the same time, 1.5 kg of urea (or 3 kg of ammonium sulfate) and 0.4 kg of potassium chloride can be applied per mu to promote development. After the disaster, vegetables are prone to downy mildew, powdery mildew or soft rot. Strengthening prevention and control should be carried out by spraying 72.2% of Plex water 600 times solution or 69% of K-M Zn WP WP 500-800 times. Prevent disease from happening.
3. cultivating soil
After the rainstorm, wait for the topsoil of the vegetable garden to be slightly dry, carry out moderate tillage in a timely manner, and properly cultivate the soil to promote the normal development of vegetables.
