Early sowing of peanuts has both advantages and disadvantages when is the best time to sow peanuts

It's the peanut season of the year, and farmers fret about when to plant peanuts at this time of year. Early sowing of peanut is beneficial to prolong vegetative growth period and increase nutrient accumulation, but it also faces many unfavorable factors. So when is the best time to sow peanuts and how to plant peanuts? Today, I will talk to you in detail.

1. Peanut planting methods:

1. Sowing method. Peanut sowing method, according to the cultivation method of open field sowing and film mulching sowing. According to the mode of operation, artificial seeding and mechanical seeding are divided.

2. Sowing density. Principle of rational close planting. Peanut planting density depends on peanut height, seed setting range and leaf area. Peanut suitable planting density depends on climate characteristics, soil fertility, varieties, cultivation conditions. Generally speaking, adopt 5×8 inch row spacing, double kernel planting, sow more than 23,000 basic seedlings per mu, harvest about 20,000 seedlings, try to use peanut specifications or use peanut hole fixer, six rows per plot.

3. Sowing depth. Peanuts are usually sown at about 5 cm. Grasp the principle of "dry not deep, wet not shallow", clay soil should be shallow, sand soil or sand nature should be deep. In open field cultivation, the deepest is no more than 7cm, and the shallowest is no less than 3 cm.

4. Suppression after sowing. Post-sowing suppression is one of the measures to ensure complete seedlings of drought resistant peanut. After suppression, it can not only reduce soil moisture evaporation, but also make the seeds closely contact with the soil, promote the water in the lower layer of the soil, prevent the seeds from falling dry, and facilitate seed germination.

Second, the best planting time for peanuts:

In summary: peanuts are thermophilic, so the temperature should be appropriate, and the most suitable temperature for peanut sowing is about 12℃, while the most suitable temperature for flowering is 23-28℃, and the lowest temperature is 19℃.

Peanut sowing time: peanut sowing, 10cm deep soil temperature for 5 days stable at 15℃ or more, you can sow. Do not sow at a temperature lower than 11 ° C to prevent rotten seedlings from dying, that is, peanuts can be unearthed, peanut seedlings are not healthy, and thus affect yield. Generally, the best planting time for peanuts is from mid-late April to early May, that is, before and after the grain rain. Plastic film mulching can be raised to the middle and late March sowing. However, the climatic conditions vary from place to place, so when planting peanuts, it should be determined according to the actual situation, but it must not be sown when the temperature is too low!

2-3 days before sowing, the seeds of peanut with shell are dried, shelled after drying, dressed with 50% imidacloprid suspension seed coating agent + full suitable gold suspension seed coating agent, and sown after drying. Sowing 2-3 seeds per hole, sowing depth of 1.5 inches is appropriate, clay soil, good moisture content of the soil, can be appropriate shallow, sandy soil, poor moisture content of the soil, can be appropriate deeper. It is suggested that plastic film should be covered in spring peanut planting area, and early sowing should be appropriate to improve peanut yield.

Summer peanut planting area optional interplanting, early sowing, improve yield.

Mastering the peanut planting method and the best planting time can not only avoid the problems caused by peanut planting problems, but also effectively increase peanut yield. However, we should remind everyone that due to the recent weather changes, we must deal with it according to the climate when sowing.
