Timely sowing. The best sowing time for wheat peanuts is generally around May 25, and sowing is completed by the beginning of June at the latest. Two seeds per hole, sowing depth of 3 to 5 cm, once the seeding watering once in time.
The cultivator removes radon. Tests have shown that, if wheat is covered with peanuts and wheat stubble is not removed and cultivated, the yield per unit of peanut will be reduced by about 20%. Cultivating rice stubble can eliminate breeding sites for pathogens and pests. It can also increase ground temperature, promote root development, and facilitate the lowering of fruit needles, thereby increasing the fruit set rate of peanuts and increasing production. After two days of watering the wheat, peanuts should be taken out of the wheat bran in a timely manner. After the cultivator is drawn, the field weeds are removed and cultivars are cultivated 2 to 3 times before the peanuts are ridged.
Topmiao fertilizer. Wheat is the wheat in front of the peanut, and consumes a large amount of nutrients in the soil during the whole growth period. After wheat is harvested, most of the lands have insufficient fertility. Therefore, it is necessary to make timely supplements to the wheat peanuts to promote the rapid growth of the plants. Fertilizer topdressing mainly nitrogen fertilizer, combined with watering topdressing urea 20 kg per acre. Harvest wheat in 3 to 5 days and apply fertilizer.
Control pests. After the wheat harvest, there will often be a period of continuous drought, high temperature and little rain. Some infatuated sand land spider mite will happen. These pests will harm the leaves of peanuts and affect the normal growth of the plants. Special special acaricide control.
1. Two-cultivation and integrated fertilization
Deep ploughing
Moderate deep plowing before wheat sowing has a significant effect on the creation of high-yielding soils, the coordination of gas and water conflicts, and the improvement of wheat intercropping peanut production.
Former fertilization
Wheat kernels can not be used as base fertilizers, and the yield depends on the basic fertility of the soil and fertilization in wheat fields. Fertilizers for the two crops should be applied before wheat is sown. The specific amount of fertilization is: after the autumn harvest, the combination of cultivated land uses 3,000-4,000 kilograms of high quality manure per acre, 50 kilograms of superphosphate, and 50 kilograms of potassium sulfate ternary compound fertilizer.
2, a reasonable choice of improved species
Peanut uses medium-mature and large-peanut high-product varieties. Sawn 2-3 times before sowing.
3, timely interplanting
The intercropping period depends on the size of the wheat canopy, taking into account the soil moisture status. High-yielding wheat fields have severe shade and the intercropping period is 10-15 days before wheat harvest. The middle-aged wheat field can be inserted in advance 15-20 days before the wheat harvest. Interplanting time must also consider the soil moisture, should be 7-10 days before sowing, combined with pouring wheat grouting water, if the lack of lyricism, but also too late to achieve cultivars, can be appropriate sowing, sowing after the first water. Planting enough seeds is the key measure to achieve Miao Qimiao.
4, rational dense planting, and strive to full seedlings.
The planting density of peanuts in wheat is generally 10,000 tons/mu. The planting method is mainly based on the wheat planting method and the principle of ensuring density. Each pier 2 tablets. The key to realizing dense planting is whether wheat can be seeded with whole peanuts. It should mainly focus on measures such as selecting seeds, planting ankles, and sowing depth.
5, scientific management
1 About 5 days after the wheat harvest, the first extermination of medlar cultivator and Mushi 15 kg of urea, diammonium 20 kg, 0.5 kg of boron fertilizer, 2000 kg of organic fertilizer, timely watering after fertilization. After the first flower, the second cultivator was taken and the weeds were removed. The third round of cultivating was carried out during the full flowering period, reaching the goal of deep-rooting the second time and the second time of the shallower three times.
2 After the flowering period, the key anti-adults are applied. Where the height of the main stalk reaches 35-40 cm, it is sprayed with 50 kg of water in 30 ml/mu of Zhuangfeng'an.
3 Timely prevention of pests and diseases: peanut aphids use 40% omethoate 60 ml watered 60 kg spray control, alum with 5% phoxim granules 2.5-3 kg fine soil 15-20 kg Shun ridge spread in peanuts Near the pier. In early August, we will adopt a combination of disease prevention and extra-root topdressing to prolong the functional period of the leaves and increase the fullness of the mangosteen by adding 0.5 kilograms of urea spray or dexamethasone plus urea to 50 kilograms of the 2.5% superphosphate solution. spray. Spray once every 15 days, spray 1-2 times.
4 Timing harvest: The appropriate harvest period for medium-mature peanuts in wheat is generally at the beginning of October. The signs of maturity are that the number of green leaves in the shoots is controlled below 5 pieces, the dynamic changes of the leaves disappear, and the underground steel shell iron mouths.
The main contradiction of the high yield of peanut in wheat:
In the wheat field, interplanting peanuts, peanuts and wheat have a period of symbiosis, forming a compound crop group, which constitutes a unique farmland ecology with the surrounding ecological factors (including soil, fertilizer, water, temperature, and gas) and other organisms. system.
Between crops and crops, crops and various ecological factors, there are both mutual adaptations and contradictory aspects. Fuda Peanuts-Peanut High-yield Creation Center. The short growing period of peanuts in the summer direct broadcast and the lack of caloric resources are the main constraints for the high yield of peanuts in the summer direct broadcast. Therefore, in the production practice, only by grasping the main contradiction and taking appropriate measures to resolve the contradictions, can we obtain high yields of wheat.
How to set wheat peanuts, wheat cultivation techniques detailed information to introduce here in detail, hoping to help everyone! In addition, the intercropping of peanuts in wheat fields, due to the early growth of peanut interplanting and wheat symbiotic, the greater the impact of shading by wheat, resulting in early-onset late, later due to lower temperatures and greed. Therefore, the birth of a group has a tendency of rising slowly in the early stage, descending in the later stage, and sharply increasing in the middle period. In cultivation, it is necessary to promote the growth rate in the mid-fertility period according to this characteristic, and try to extend the duration of this growth peak as the main focus.
