Wheat sets of peanuts before the wheat is harvested, the peanuts are planted in the wheat row, in order to extend the growth period of peanuts, make up for the lack of heat resources, to achieve the wheat and peanut two crops a year, which is to ensure a high yield of peanut, wheat a planting system.
In recent years, affected by the adjustment of the price of corn and planting structure, the original areas in which summer corn was planted have also started to develop summer peanuts, and more and more farmers are consulting the wheat cultivation technology. Because of the symbiosis period of wheat peanuts, wheat peanuts have higher technical requirements for peanut planting, especially sowing. If this is not done well, it will be difficult to achieve full seedlings, Miao Qi, and Miao Zhuang, which will have a great impact on peanut production.
Right now, when it comes to the sowing season for wheat, we must do the following three tasks.
First, the appropriate sowing, and strive to strong seedlings
Peanut and wheat have a symbiotic period of about 10 days. If peanuts are planted too early and the symbiotic period is long, peanuts tend to form tall plantlets, affecting growth and development and flower bud differentiation. Even if the management of wheat is strengthened after the harvest, it will be difficult to make up for it; if the planting is too late, the full development of peanuts will not be affected and prolonged fertility cannot be achieved. The purpose of the period is not to meet the requirements of accumulated temperature of peanuts to the maximum extent, resulting in late filling of the pods that cannot be full and full, reducing the rate of kernels, and at the same time increasing the degree of damage to the peanut seedlings during the harvest process, resulting in reduced yields.
The interplanting period of peanuts mainly depends on the way of wheat planting, the size of the population and the extent of field canopy closure. Usually wheat interplanting peanuts should be sowed 15 to 20 days before the harvest of wheat, middle and high yield wheat fields, shade is serious, interplanting period should be appropriate after the shift, low-yield wheat fields, the use of wide and narrow rows of wheat fields, can be interplanted in advance. In the south-central part of the province, the best sowing date for wheat and peanuts is generally from May 20 to the end of May. The southern part should be early, the north should be late, and the seeding should be completed by the beginning of June at the latest.
Second, rational dense planting, and strive to full seedlings
The reasonable planting density of wheat peanuts is generally 10,000 to 11,000 holes/mu, and 2 seeds per hole. Peanut ridge spacing is mainly determined according to wheat planting methods, in order to ensure the principle of density. Peanuts have a large ridge distance, and the distance between the ridges should be appropriately reduced. The peanut ridge distance is small, and the distance between the ridges can be increased. Note that the ridge distance is greater than the distance between the holes, and the "Gypsophila" planting method is not recommended.
In order to ensure a reasonable planting density, seeds should be carefully selected before sowing. Peanuts, diseased grains, and bad grains should be removed after peeling the shells. Grains that are full, bright, no spots, and no damage should be selected as seeds. Seeds are sorted after sowing. In order to prevent root rot, stalk rot, and underground pests from affecting planting density due to lack of seedlings and ridges, seed dressing is required before sowing. When sowing seeds, the quality of sowing should be ensured, the depth of sowing should be the same, and the soil should be covered tightly.
Third, appropriate planting, and strive to Qimiao
Peanuts must also consider the soil moisture when interplanting peanuts. Normally, peanuts should be planted before sowing, and they should be planted properly. Generally should be 7 to 10 days before the interplanting of peanuts, combined with pouring wheat grouting water to make oysters, if the lack of lyrics, not too late to make oysters, can be appropriate sowing, sowing after the first water. However, the land of clay and soil is best planted after the first crop. Sandy land and sandy soil can be planted after the first planting and watering can be conducted after sowing. Full planting is the key to achieving Miao Qimiao.
