How to grow peanuts, the time and method of planting peanuts

Planting time: the suitable sowing time in the spring and autumn double cropping peanut area in South China is from February to mid-March. Leveling the land: the plots where peanuts are planted should be deeply turned over. Cultivated varieties: Fuhua series varieties and Jifu series varieties. Scientific fertilization: 30 tons of farm manure per mu. Replenish inter-seedling: finish the work of inter-seedling and fixed seedling from late May to early June. Qinggu squatting seedlings: gently pick 2 cotyledons out of the ground with your hands. Shovel in time: it is beneficial for the fruit needle to stick into the soil.

First, planting time

The main results are as follows: 1. The suitable sowing time of spring and summer peanut intercropping area in the Yangtze River basin is from March to late April, the suitable sowing time of spring and autumn double cropping peanut area in South China is from February to mid-March, and the suitable sowing time of large peanut area and peanut producing area in North China is from late April to early May.

2. When sowing peanuts, the soil temperature at the depth of 10cm lasts for 5 days, or stabilizes above 15 ℃ before sowing, and the temperature below 11 ℃ can not be sowed, so as to avoid the phenomenon of rotten seeds and dead seedlings. Interplanting can be selected in summer peanut planting areas, and sowing in advance is beneficial to increase yield.

II. Formation of land

1. Peanut is a kind of cash crop that blossoms on the ground, forms a fruit needle and drills into the ground to bear fruit, so it is suitable to be planted in loose sandy soil or oil sandy soil.

2. combined with the application of 30-40 tons of high-quality farm manure per mu and suppressed 1-2 times after ploughing, areas with conditions can be irrigated first, and then mixed with farm manure and chemical fertilizer into ridges and ditches, ridging and suppression, ready to sow seeds in time.

III. Cultivated varieties

The main results are as follows: 1. the main peanut varieties suitable for planting are Fuhua series varieties and Jifu series varieties, and the growth period is about 110-120 days.

2. The pods with neat shape, large and full fruit and no broken pods can be selected as seeds. The pods should be dried for 1-3 days before shelling, and the seeds with pure color and neat shape should be selected for seed after peeling.

IV. Scientific fertilization

General peanuts are relatively resistant to barren, fertilization is mainly based on base fertilizer, 30 tons of farm manure can be applied per mu, chemical fertilizer needs to be mainly phosphate fertilizer, 300-400 jin diammonium phosphate per mu, growing peanuts in barren land, 200-300 jin urea per mu.

Fifth, replenish inter-seedling seedlings

From late May to early June, it is necessary to investigate the seedling situation as soon as possible, and for the fields with obvious lack of seedlings, the seedlings need to be replenished in time, and the method of promoting budding and sitting water can be used to complete the work of interseedling and seedling determination at the same time.

6. Qingge squatting seedlings

When peanut seedlings come out, dig a circle of soil around the seedlings far away from 2cm, and then gently pick the two cotyledons out of the ground by hand. The squatting seedlings are usually carried out 3 days after the first shovel.

7. Shovel in time

Shovel the peanut seedlings after they are unearthed, do the first shovel 3 days after shoveling, shovel twice after 15-20 days, pay attention to cultivate the soil not to press the seedlings, shovel 3 times at the end of the full flowering period, and four square ridges when sealing ridges, which is beneficial for fruit needles to be inserted into the soil, and pay attention to pulling out weeds at the same time.

8. Reasonable topdressing

Peanuts in the pod and full fruit stage, according to the growth situation, foliar spraying 0.3% potassium dihydrogen phosphate, as well as Lvfeng 95 and other plant growth regulators, is conducive to promote grain formation.

IX. Timely harvest

When the leaves of peanuts turn yellow, some of the stems and leaves wither and dry, and they can be harvested. Generally in the middle of September, it is necessary to dry and rain after harvest, which is beneficial to promote post-ripening and improve seed maturity, while peanuts need to be harvested and dried before frost.
