Peanut anti-drought and disaster reduction technical measures
Hubei: According to the characteristics of high temperature and low rainfall season in Hubei Province, the following measures can be taken mainly: first, sowing in advance to avoid the high temperature and little rain season; second, mulching.
Henan: Firstly, actively coordinate with government departments, and propose to closely track the weather process, seize favorable opportunities, make full use of clouds, implement artificial rainfall, reduce the expansion of drought conditions, and carry out artificial rainfall enhancement operations in case of favorable weather conditions to increase rainfall. To relieve droughts to the maximum extent; guide farmers to increase their awareness of water-saving irrigation in drought- and drought-stricken fields; draw lessons from disasters; increase irrigation efforts in dry fields to promote the progress of water-saving irrigation; and conditional farmers spray anti-drought and water-retaining agents to promote crop growth. At the same time, it also adhered to the combination of engineering measures, biological measures, and farming measures, and continuously expanded the area of ​​application of biological agents such as water-retaining agents to enhance the drought resistance of plants. Strengthen the prevention and treatment of field diseases and insect pests in the late growth period of peanuts, prevent the high incidence of diseases and insect pests caused by drought, and secondly, prevent farmers from replanting crops with short-term growth and drought-tolerant late-autumn crops to minimize drought damage. At the same time, farmers' water-saving irrigation is organized to increase water use efficiency. In the future, some varieties of drought-tolerant and ridge-tolerant varieties should be planted, such as Huaihua 28, Gandonghua 1, Shaohua 9519, Yuhua 9326 and Yuanza 9847.
Shandong: The first is to strengthen fertilizer and water management, promote vegetative growth of peanuts, increase plant biomass, delay aging and promote full filling of pods. Fertilizers are mainly nitrogen and phosphate fertilizers, with certain trace fertilizers such as boron, molybdenum, and iron. The land with irrigation conditions can be topdressed on the ground. If there is no irrigation condition, it can be sprayed on the surface. The second is to strengthen the control of leaf spot. In the middle and late stages of peanut growth, leaf spot disease is one of the most widely distributed and most harmful diseases. It causes the leaves to yellow and fall off, which affects the maturation of the pods and causes the increase of pods. Application of fungicides is an important measure to control leaf spot disease.
Hebei: First, timely irrigation, in areas with irrigation conditions, in the high temperature continued weather, timely observation of peanut seedlings, see the growth status of plants, depending on the degree of drought timely watering. Master the timing of proper irrigation, can not wait until the plants appear wilting irrigation. Watering time should be selected in the afternoon and early evening. Advocate appropriate irrigation to prevent premature aging; Second, spray drought-resistant chemical agents, and apply drought-repellent fulvic acid in a drought-prone field. Use: 1125 g of fulvic acid powder per hectare, watered 750 kg, evenly sprayed on peanut plants. It can effectively relieve the impact of drought on peanut development and promote the growth of the ground.
Liaoning: Experts of this system actively issued drought notices, contacted peanut demonstration counties to actively launch anti-drought plans, used all available sprinkler irrigation facilities for drought relief, and responded to weather-sudden rain and timely replanted cash crops such as vegetables; And with the persistence of high-temperature weather, we must promptly do a good job of prevention and control of pests and diseases.
Jilin: Irrigate on time, in areas with irrigation conditions, keep the weather at high temperatures, observe the peanut seedlings in time, watch the growth status of the plants, and water them timely depending on the degree of drought. Master the timing of proper irrigation, can not wait until the plants appear wilting irrigation. Watering time should be selected in the afternoon and early evening. Advocate appropriate irrigation to prevent premature aging; Spray drought-resistant chemical agents, and spray fulvic acid-based drought-resistant agents in time on drought-heavy fields. Use: 1125 g of fulvic acid powder per hectare and 750 kg of water Spray evenly on drought-tolerant peanut plants. It can effectively relieve the impact of drought on peanut development and promote the growth of the ground.
