Detailed Explanation of Post-Autumn Management Techniques for Chili Peppers

I. Cooling and Moisture Retention.

During the autumn period of drought and relatively high temperatures, irrigation should be carried out in a timely manner to keep the soil moist. When irrigating, the principle of "first shallow, second quick, third cool" should be followed, that is, irrigate shallowly without flooding the beds; irrigate quickly and drain quickly, without letting the field water stand for long; irrigate when the soil is cool, the water is cool, and the weather is cool, with the best time generally being from midnight to before dawn. In addition, using crop straw such as rice straw and wheat straw to cover the bed surface can both lower the ground temperature and reduce water evaporation, thereby helping to retain water and moisture and extend the plant's growth period. If rainy weather occurs, the ditches should be cleared promptly for drainage, so that the field dries after the rain stops.

II. Topdressing to Promote Growth.

In the high-temperature season, in combination with irrigation, apply dilute human and livestock manure water 2 to 3 times per mu, each time 1000 to 1500 kg per mu, and it can be splashed on after irrigation when the soil is slightly dry. After the weather turns cool, chili peppers enter the vigorous fruiting stage, and the plants' fertilizer demand increases. Before the end of October, topdressing should be applied 3 to 4 times, with 10 kg of compound fertilizer per mu each time, to promote vigorous plant growth and improve the yield and quality of chili peppers.

III. Protecting Roots and Preserving Leaves.

In later-stage management, special attention should be paid to protecting the roots and leaves of chili peppers. Once pests and diseases are found, pesticides with high efficiency, low toxicity, and a short residual period should be applied promptly for control, so as not to damage the leaves. When cultivating and weeding, methods such as shallow hoeing and manual pulling should be used to prevent damage to the root system and avoid affecting the plant's absorption capacity. Wang Qinglong
