Wheat and peanut cultivation technology

Wheat peanuts are a kind of peanut planting, especially in the middle and south plains of Hebei Province. The area of ​​wheat peanuts is relatively large, but many growers do not understand the knowledge about how to put wheat peanuts. Today, we will analyze the wheat jackets in detail. Peanut cultivation techniques.

Sowing at the right time. The best sowing time for wheat peanuts is generally around May 25, and at the latest in early June. Sowing two seeds per hole, sowing 3 to 5 cm deep, and pouring the head water once in time.

Cultivate and remove mites. Tests have shown that if the peanuts are not removed from the wheat and the cultivating, the yield per unit of peanuts will be reduced by about 20%. Cultivating and removing mites can eliminate the breeding sites of germs and pests, and can also increase the ground temperature, promote the development of roots, and facilitate the lowering of fruit needles, thereby increasing the fruit setting rate of peanuts and increasing the yield. After two days of watering the peanuts, the wheat sorghum should be removed in time, and then the cultivating and raking, and the weeds in the field should be removed, and the ploughing should be carried out 2 to 3 times before the peanuts are closed.

Follow the seedlings. The wheat stalks are wheat, which consumes a lot of nutrients in the soil during the whole growing season. After the wheat harvest, most of the plots have insufficient fertility. Therefore, it is necessary to timely apply the seedling fertilizer to the wheat straw to promote the rapid growth of the plant. Topdressing should be based on nitrogen fertilizer, combined with watering 20 kg of urea per acre. After 3 to 5 days of wheat harvesting, fertilize and water in time.

Control pests. After the wheat harvest, there will often be continuous drought, high temperature and low rain. Some thin sand land red spiders will be paralyzed. These pests will harm the leaves of peanuts, affecting the normal growth of the plants, and should be prevented early. Special purpose acaricide control.

1. Two-pronged farming and fertilization integration

Squatting

Appropriate deep ploughing before planting wheat has a significant effect on creating high-yield soils, coordinating gas and water conflicts, and improving wheat intercropping peanut yield.

Forehead fattening

Wheat peanuts can not be applied to the base fertilizer. The yield depends on the soil basic fertility and fertilization in the wheat field. The fertilizer needed for the two crops should be applied before the wheat is planted. The specific amount of fertilization is 3,000-4,000 kg of high-quality ring fertilizer, 50 kg of superphosphate and 50 kg of potassium sulphate ternary compound fertilizer per acre combined with cultivated land.

2. Reasonable selection of good varieties

Peanuts use high-yield varieties of medium-maturing large peanuts. Soak the seeds 2-3 times before sowing.

3, timely interplanting

The intercropping period depends mainly on the size of the wheat canopy, while taking into account the soil moisture status. High-yield wheat fields, severe shading, intercropping period is 10-15 days before the wheat harvest. The middle-aged wheat fields can be properly advanced to 15-20 days before the wheat harvest. Interplanting time must also consider the soil moisture, 7-10 days before sowing, combined with pouring wheat grout water to make sputum, if the lack of sensation, and too late to make sputum, can be planted in a timely manner, after planting, watering the head water. Sowing of the foot is the key measure to achieve the seedlings.

4, reasonable close planting, and strive to be full seedlings.

The density of peanuts planted in wheat is generally 10,000 mounds/mu. The planting method is mainly based on the method of wheat planting to ensure the density. 2 pieces per pier. Whether the whole set of peanuts can be fully planted is the key to achieving close planting. It is necessary to focus on the selection of seeds, the sowing of the ankles, and the consistency of sowing.

5. Scientific management

1 About 5 days after the wheat harvest, the first time the cultivating cultivating and cultivating 15 kg of urea, 20 kg of diammonium, 0.5 kg of boron fertilizer, 2000 kg of organic fertilizer, and timely watering after fertilization. After the initial flowering, carry out the second cultivating and pay attention to the weed removal. In the flowering period, the third round of cultivating was carried out, and the purpose of cultivating the fruit needle was achieved three times in the first two times.

2 After the flowering period, the key defenses are long, and the plots with the main stem height of 35-40 cm are sprayed with 30 kg of water per 30 ml of Zhuangfengan.

3 timely control of pests and diseases: peanut aphids with 40% omethoate 60 ml water with 60 kg spray control, 5% acres with 5% phoxim granules 2.5-3 kg with fine soil 15-20 kg sloping ridges on peanuts Near the pier. In the first half of August, we will focus on combining disease prevention with external topdressing to extend the functional period of the leaves and increase the fullness of the pods. That is, adding 0.5 kg of urea spray or using zinc and urea in 50 kg of 2.5% superphosphate clarification solution. spray. Spray once every 15 days and spray 1-2 times.

4 timely harvest: the harvest period of the mature peanuts in the wheat jacket is generally in early October, the mature sign is that the number of green leaves in the shoot is controlled below 5, the dynamic change of the leaves disappears, and the steel shell of the underground is iron mouth.

The main contradiction between the high yield of wheat and peanuts:

Wheat field interplanting peanuts, peanuts and wheat have a symbiotic period, forming a composite crop group, which constitutes a unique farmland ecology with surrounding ecological factors (including soil, fertilizer, water, temperature, gas) and other organisms. system.

Between crops and crops, crops and various ecological factors, there is a mutual adaptation side and contradictory side, Fuda Peanut Net-Peanut High Yield Creation Center. Summer live broadcast peanuts have a short growth period, and insufficient caloric resources are the main limiting factors for the high yield of summer live peanuts. Therefore, in the production practice, only by grasping the main contradictions and taking appropriate measures to resolve the contradictions, can we obtain high yield of wheat peanuts.

How to plant wheat peanuts, detailed information on the cultivation technology of wheat peanuts will be introduced here in detail, I hope to help everyone! In addition, the intercropping of peanuts in wheat fields, due to the early intercropping of peanuts and the growth of wheat symbiosis, is greatly affected by wheat shading, resulting in late bloom in the early stage and later greedy due to lower temperature. Therefore, the group's fertility has the characteristics of slow rise in the early stage, slow down in the later period, and sharp increase in the medium term. In the cultivation, it is necessary to promote the growth rate in the mid-fertility according to this feature, and to maximize the duration of this growth peak as the main focus.
