Post-autumn management of hot pepper

Chili peppers are cultivated in the open field, and the harvest period is from June to November. Although the output of chili peppers after autumn only accounts for 30%-40% of the total output, but since September to November is the off-season in the fresh pepper market, the price of fresh peppers in this period is high, and the economic benefit is often 3-4 times higher than when the pepper is concentrated on the market in the prosperous fruit period. However, it is customary to relax field management after the harvest period (July), resulting in a decline in plant growth and a rapid decline in yield, resulting in almost no harvest after autumn. Therefore, it is necessary to strengthen the post-autumn management of pepper, protect the plant, and obviously improve the economic benefit. The main measures are as follows:

First, cooling and moisturizing. In the period of drought and high temperature in autumn, it is necessary to divert water to irrigate in time to keep the soil moist. When irrigation, it is necessary to grasp the principle of "one shallow, two urgent, and three cool", that is, shallow irrigation does not spread the border; urgent irrigation will lead to a short stay of field water; when the soil is cold and the weather is cool, it is usually best to irrigation from 00:00 at night to before early morning. In addition, covering the border with straw, wheat straw and other crops can not only reduce the ground temperature, but also reduce water evaporation, retain water and moisture and prolong the growth period of plants. In case of rainy weather, it is necessary to clear the ditch and drain in time so that the rain stops the field to dry.

Second, topdressing to promote growth. In the high temperature season, rarefied human and animal manure water is applied 2 times per mu combined with irrigation, with 1000-1500 kg per mu each time, which can be poured when the soil is slightly dry after irrigation. After the weather turned cool, the pepper entered the vigorous fruiting period, and the fertilizer requirement of the plant increased. Before the end of October, topdressing should be applied 3-4 times and compound fertilizer 10 kg per mu, so as to promote the vigorous growth of plants and improve the yield and quality of hot pepper.

Third, protect the roots and leaves. In the later stage, special attention should be paid to the protection of pepper roots and leaves. Once diseases and insect pests are found, pesticides with high efficiency, low toxicity and short residual period should be applied in time to prevent the leaves from being damaged. Shallow ploughing and manual pulling should be used to prevent damage to the root system and affect the absorptive capacity of the plant. He Fang
