The wheat in Henan Province is about to usher in the harvest. Many farmers have begun to prepare peanuts. Then, how should peanut varieties be selected, what are the differences between wheat and peanuts in summer, and what should be paid attention to during the planting process?
Wheat and peanuts should be selected from medium and early maturing products, such as Yuhua No. 15, Yuhua 9327, Yuhua 9331, Yuhua 9502, Yuhua 9326, and Yuanza 9847. The sowing time is about 15 days before the wheat harvest. Because it is planted in the wheat field, the emergence is poor and it is not easy to fully seedling. Therefore, the seeding amount should be appropriately increased, and the planting should be reasonably densely planted. The summer directing peanut has a short growth period and poor individual development. Early maturing and densely planted peanut varieties. Peanut varieties such as Yuhua 9327, Yuanza 9847, Yuanza 9102, Yuanza 9307, Yuhua No.1, Yuhua 22, Yuhua 23 can be selected according to local conditions. The peanut seeds that are broadcast live in summer should be selected from the well-stocked and well-preserved seeds.
The yield of summer live peanuts is highly correlated with sowing in the morning and evening, and the earlier the sowing, the higher the yield. Therefore, it should be planted as early as possible, the sooner the better, at the latest no later than June 20, the seeding depth is generally about 5 cm. At the same time, mechanized sowing should be used as much as possible, so that the herbicide can be planted and sprayed once.
Peanut growth critical period, planting management to keep up
Experts said that for wheat peanuts, wheat should be smashed in time after harvesting, early fatning to promote early seedlings, to make up for the impact of wheat and peanut symbiotic period on peanut growth and development, and to cultivate strong seedlings. The wheat ridge interplanting peanut field generally uses selective post-emergence herbicides, such as turfgrass, kekuole, etc., and is used in peanut seedlings. In addition, due to the high temperature in summer, the wheat peanuts grow rapidly, and it is easy to grow up. When the main stem height of the peanut reaches 35 cm, it should be timely controlled to prevent the long-term lodging.
For summer live peanuts, due to strong growth, the amount of fertilizer needed is large. Before the sowing, the base fertilizer should be applied, the organic fertilizer should be added, the quick-acting fertilizer should be supplemented, and the micro-fertilizer should be applied. Generally, 2500-3000 kg of organic fertilizer per acre, 6 kg of nitrogen, 12 kg of phosphorus and 12 kg of potassium are used to increase the fruit weight. Generally, 50 kg of calcium fertilizer is applied per mu. According to the growth period, appropriate foliar application of micro-fertilizer can improve plant resistance, slow down aging and increase yield.
At the same time, the summer high-yield peanut field, due to the early growth and development, the mid-term growth is prosperous, easy to cause group depression, lodging, affecting photosynthesis leading to reduced production, generally when the plant height reaches about 35 cm, spray paclobutrazol, olefin effect The azole and the like are controlled.
The summer and autumn rains vary greatly, and the field management is unpredictable.
For wheat-covered peanuts, in case of autumn drought, you should immediately lightly pour the water to increase the pod fullness. It is rainy in autumn, which is easy to cause rotten fruit. It should be drained in time to prevent waterlogging. Peanuts should be harvested in time after maturity to prevent fruit drop and rotten fruit, and improve the quality of pods and kernels.
For summer live peanuts, in the flowering and needle-forming period, if the leaves are white and wilting, they should be irrigated immediately. Due to the heavy rain during the growth period, it is easy to cause soil oxygen deficiency. Therefore, the gully is cleaned up after the rain to eliminate the accumulated water.
Summer live peanuts should be harvested in time after maturity. The maturity standard of peanuts is more than 80%. The color of the pods is deeper, the netting is clear, the kernels are full, and the seed coat is intrinsic color of the variety. In addition, when the average daily temperature of the sunny day falls below 15 °C, regardless of plant length and pod maturity, it should be harvested.
