Field Management Technology of Black Peanut

Peanut is a common crop in our life, which can not only be eaten raw, but also can extract oil, which is essential in our life, and a variety of peanut has a very high content of selenium, which is different from ordinary peanuts. Its seed coat is black. In recent years, the market is relatively broad, and there are many growers, so how to manage black peanuts in the field? Come and have a look with the editor.

1. Seedling stage management

Seed sprouts often die because of seed quality, lack of soil moisture, diseases and insect pests, low temperature and other adverse weather effects. Lack of seedlings and broken ridges. Therefore, the seedlings should be checked in time after sowing for 10-15 days, and the phenomenon of missing seedlings should be replanted in time to ensure the whole seedling.

2. Pest control

The period from May to June is the period when peanut aphids occur. To take prevention and control measures in advance, 25% Aktai 6g-10g per mu or 44% 30ml-60ml EC plus water 30kg can be sprayed per mu. In June, 2kg per mu of ground insects can be used to control grubs and golden needles around peanut roots mixed with fine soil l0kg. In July, you can use Daconine 80ml per mu, add water 30kg spray 1-2 times, this can effectively control leaf spot and rust.

3. Watering in case of drought

So that there is an appropriate amount of water in the ditch, in order to moisturize from the ditch to the ridge, and strictly prevent the flood from flooding the ridge surface. After watering, under the appropriate condition of dry and wet, ploughing once in the ridge and furrow, to prevent soil consolidation, to ensure that the fruit needle into the soil and pod expansion, in time to drain water, so as to avoid rotten fruit.

4. temperature control and prevention of premature senility

In the period of needle setting and podding of peanut, because of the high temperature and heavy rain, it is easy to cause the plant to flourish and grow. In order to control the vigorous growth, we should spray water 40kg foliar once or twice with about 20g of Zhuangzuan per mu from the late stage of needle setting to the early stage of podding. This can not only control the growth, but also control the gibberellin biosynthesis in the plant, reduce cell division and elongation, inhibit vegetative growth, promote reproductive growth, and effectively improve yield and quality. In addition, we should also pay attention to the premature senescence of black peanuts. Urea and potassium dihydrogen phosphate solution can be sprayed 40 days before harvest to delay the photosynthesis of stems and leaves and enhance the absorption capacity of roots. Promote the accumulation of dry matter.
