Due to its high economic efficiency, easy cultivation and management, and favorable land recycling, Xia Peanut has become the first choice for many growers. To get high yields, you need to start with the following points.
It is an intrinsic factor to achieve high yield by selecting early-maturing varieties with high yield potential and selecting varieties with high yield potential. In 2012, Zhengzhou, Henan Province, Henan Province, after the harvest of garlic, planted early-maturing large peanuts "Yuyu 502", the average yield of 8 mu of pods reached 625 kg. At present, the new varieties of large peanuts are Qinghua 7 and Huayu 36. The small peanut variety is the blue-flower variety No. 6 or a high-yield and excellent variety suitable for local cultivation.
Implementing peanut summer live broadcast protective cultivation method to increase efficiency, mechanized sowing black plastic film covering W cultivation method, innovative cultivation technology, is the special expert of Benyu Enterprise in Yangling Demonstration Zone, Shaanxi Province - Professor Cai Changjiu, Director of Pingdu Peanut Research and Development Center and Qingdao The Agricultural University collaborates to study the latest cultivation methods of inventions. In 2011, he won the national invention patent certificate. This method can greatly increase the yield of peanuts.
Adding 30-50 kg of ammonium bicarbonate or 20-30 kg of urea per acre before applying nitrogen fertilizer and foliar spray fertilizer, in addition to satisfying the nitrogen requirement of peanut seedlings, it can also promote the rot of wheat straw. Peanut foliar spray fertilizer has many advantages such as rapid action, balanced nutrition, low input cost, and significant yield increase effect. In order to release the seedlings, the two real leaves will start to spray fertilizer, and the “Lingbao†or “Green Control and Sui'an†will be sprayed at intervals of 10 to 12 days.
Control pests and diseases The main pests of summer peanuts are underground pests such as cockroaches and golden worms. Seedling stage aphids (black volts) and leaf-feeding pests during growing season. The main diseases are dead seedlings caused by blast disease in the seedling stage, and early leaves caused by leaf spot disease in the middle and late stages. Control method: Before sowing, seed dressing with 2.1% of the weight of the seed. At the time of sowing, 1.0 kg of active ingredient per acre, 10% of the "speed-killing worm" cover species or with fertilizer into the ground. In combination with foliar spray fertilizer, when there is damage to the leaf-feeding pests, the insecticide is mixed; when there is a prosperous sign, the regulator is mixed, and the fungicide is mixed in the middle and late stages.
In the middle and late period, when the peanuts are not grown in the summer, when the peanuts are grown to the middle and late stages, it is the autumn that is high in air and the temperature difference between day and night is large. At this time, moderate drought is conducive to the fruit pods to achieve high yields. Do not water as long as there is no permanent wilting for a long time.
Appropriate late harvest as long as the middle and late leaf protection measures are done well, the middle and upper leaves do not fall and are not in a hurry to plant the crops under the hoe, which can be properly received late.
