How to grow peanuts for "common food"?

Peanut is a very common food in our life, many people have eaten it, it not only has high nutritional value, but also has a wide range of applications, not only can it be eaten directly or as a food material, but also can be used as oil and feed, etc., the market demand is large, the planting prospect is good, many growers also want to grow, so how to grow peanuts?

I. formation of land

Peanuts are cash crops that blossom and form fruit needles on the ground and are suitable for planting on loose sandy soil or oil sandy soil. in addition, peanut plots should be deeply turned over with 30-40 tons of high-quality farm fertilizer per hectare and suppressed 1-2 times after turning. Where possible, irrigate first and then apply a mixture of agricultural fertilizer and chemical fertilizer into ridges and ridges to suppress sowing in time.

2. Selection of varieties

Improved varieties of peanuts are the basis for high yield. the peanut varieties suitable for planting mainly include Fuhua series varieties and four-grain red varieties, and the growth period is about 110-120 days. in addition, pods with neat shape, large and full fruit and no broken pods can be selected as seeds. Seeds with pure grain color and neat shape should be further selected after drying for 1-3 days before shelling.

III. Scientific fertilization

When planting peanuts, the main fertilization should be base fertilizer, and the fertilization method is about 30 tons of farm manure per hectare and 300-400 jin diammonium phosphate fertilizer per hectare, while 200-300 jin urea per hectare should be added to grow peanuts in barren land.

Fourth, replenish inter-seedling seedlings

The investigation of seedling situation should be carried out as soon as possible from late May to early June, the seedlings of peanuts should be checked in time after emergence, and the fields with obvious lack of seedlings should be replenished by the method of sprouting and sitting water as soon as possible. complete the work of fixing seedlings so that the number of seedlings per unit area can reach the planned number, which is usually carried out 3-5 days after emergence.

5. Qingge squatting seedlings

Qinggu squatting seedlings are usually carried out three days after the first shovel. When the peanuts are ploughed for the first time, dig a circle of soil around the seedlings 2 cm away with a small hand pick hoe, and then gently pick the two cotyledons out of the ground with your hands. This is conducive to the strong development of the first pair of lateral branches and make the seedlings grow healthily. After the peanut seedlings are unearthed, shovel, 3 days after shovel, shovel twice after 15-20 days, pay attention to do not press the seedlings. At the end of the flowering season, shovel three times, and when closing the ridges, go to the square ridges to facilitate the fruit needle to stick into the soil at the same time pay attention to pulling out the big grass.

VI. Watering and drainage

Peanuts are afraid of both drought and waterlogging. Peanuts need water in a certain stage, and it does not need much water before the flowering and needling period. after this stage, its water demand gradually increases, and it needs to be watered and replenished in time to ensure the growth of the plant. however, we should also pay attention to the fact that stagnant water in the field can not be discharged in time so as not to affect root respiration and cause rotting roots.

7. Reasonable topdressing

According to the growth situation, peanut can be sprayed with foliar fertilizer such as potassium dihydrogen phosphate and plant growth regulators such as Lvfeng 95 to promote grain formation. In addition, the podding stage of peanut is when the ability of peanut root is the weakest, so it is suitable to apply foliar fertilizer to supplement plant nutrition.

VIII. Appropriate prevention and control

In order to prevent the overgrowth of the plant about a month after flowering, paclobutrazol can be sprayed on the leaf surface for chemical control when the plant grows too much or there is a premature closure in the field, so that the yield can be increased by 10% if applied on the field with overgrowth.

IX. Disease prevention and control

Peanuts are easy to be infected with leaf spot and peanut rust during growth. Leaf spot can be controlled with 70-80 kg 1000-fold topiramate per mu or 70-80 kg 50% carbendazim 800-1000 times per mu. Peanut rust can be controlled with 30-40 ml 20% trimethoprim EC per mu to control 40 kg of water.

Harvest at the right time

Generally in the middle of September, when peanut leaves turn yellow and some stems and leaves wither, they can be harvested. After harvest, it is necessary to dry and rain to promote post-ripening and improve seed maturity, while remaining peanuts should be harvested and dried before frost.

Summary: the above is the relevant introduction of peanut planting methods. Generally speaking, as long as you master good planting methods and techniques, the output of peanut planting is still good, and the economic benefits obtained are also OK. The above planting methods growers can refer to their own actual situation, hoping to help friends in need!
