Cultivated peppers are cultivated in the open field and the collection period lasts for more than 5 months from June to November. Practice has proved that although the production of pepper in autumn is only 30% to 40% of the total output, but due to September to November is the off-season of the fresh pepper market, the price of fresh pepper during this period is high, the economic benefits are often concentrated in the season of chili fruit 3 to 4 times. However, it is customary to relax field management after harvesting the fruit period (July), causing plant growth to decline, small and deteriorated fruit, and rapid decline in yield, resulting in almost no harvest in autumn. Therefore, strengthening the management of peppers in the autumn and protecting the plants can increase the yield of autumn peppers and increase economic efficiency. The main measures are as follows: First, cooling and moisturizing. In times of drought and high temperatures in the fall, timely irrigation should be conducted to keep the soil moist. When watering, it is necessary to master the principle of “a shallow, two urgent, and three coolâ€, that is, shallow irrigation is not diffuse; emergency irrigation rush, Tianshui stays for a long time; soil cooling water is cold when the weather is cold, generally water is poured before dawn. optimal. In addition, the use of rice straw, wheat straw and other crop stalks cover the sorghum surface, not only can reduce the temperature, but also reduce water evaporation, can play a role in water retention and moisturizing and prolong the growth period of the plant. In case of rainy weather, it is necessary to clear the ditch in time so that the rain will stop drying and create a good growing environment for the pepper. Second, chase fertilizer promote long. In the hot season, combined with irrigation per acre topdressing thin manure dung 2 to 3 times, each time 1000 ~ 1500 kilograms per acre, can be poured in the soil slightly dry when pouring water to supplement the loss of fertilizer. After the weather turns cold, the peppers enter a vigorous result period. Plants need to increase the amount of fertilizer. Before the end of October, fertilizer should be topdressed 3 to 4 times, and 10 kg of compound fertilizer should be applied per acre to promote vigorous plant growth and improve the yield and quality of pepper. Third, protect the root leaves. In the later period of field management, special attention should be paid to the protection of the roots and leaves of peppers. Once pests and diseases are found, pesticides with high efficiency and low toxicity and short residue period should be promptly applied to prevent damage to the leaves. When weeding and weeding, methods such as shallow planing and artificial extraction should be adopted to prevent damage to the root system and affect the plant's absorptive capacity.
