Seeding time
The most suitable temperature for peanut seed germination is 25 degrees -35 degrees, the germination rate decreases when it is higher than 41 degrees, and it cannot germinate when the temperature is lower than 10 degrees and higher than 46 degrees, and the minimum germination temperature is 12 degrees -15 degrees. The most suitable temperature for seedling growth is 20 degrees -27 degrees, and the average temperature exceeds 25 degrees, which can shorten the seedling period, grow the stem and branches, and elongate the node, which is not conducive to squatting seedlings. Therefore, peanut spring open-field planting requires a ground temperature of 5 cm above 12 degrees.
Choose good varieties
Before planting, it is necessary to carefully select varieties suitable for local cultivation.
Loose and fertilized soil
It is necessary to apply organic fertilizer to the peanut planting plot and then carry out deep ploughing, which can loosen the soil and eliminate residual pests and diseases. Deep ploughing is generally about 30 cm, and deep soil can be up to 40 cm deep.
Hsiang-hsien
The selected seed fruits (full, neat, no damage, no pests and diseases) are dried at 20°C-30°C, and it takes about 2-3 days to dry. 3-5 days before sowing, peel off the husks of the peanuts. The peeled kernels are dressed with 25% carbendazim wettable powder, and can also be mixed with peanut special seed dressing, which can effectively prevent pests and diseases.
Field management
Check the seedlings and fill the gaps. After the peanut seedlings are basically complete, a comprehensive seedling inspection should be carried out to promote germination and replanting. The best way is to use tools to sow more seedlings when sowing peanuts, so as to transplant and fill the gaps when the seedlings are missing.
Clear the seedlings. Clearing seedlings is one of the most important measures for peanut field management. It is based on the peanut cotyledons are not easy to unearth and semi-unearthed characteristics, in the basic seedlings, with a small hoe to dig up the soil around the base of the peanut sprouts, to form a "small nest", so that the two cotyledons and germ exposed outside the soil, quickly accept the sun, promote the growth of seedlings and obtain increased yield.
Look at the seedling top dressing. Peanut topdressing is a supplementary measure for insufficient basal fertilizer, which should be determined according to soil fertility, basal fertilizer dosage and peanut growth status.
Cultivating soil. The number of times of soil cultivation in peanut is mainly based on the growth stage of peanut. Generally, late-maturing large peanuts can be cultivated 3 times, and the cultivation requires "the head is deep, the second is shallow, and the third is fine".
