When do peanuts step on seedlings and when do autumn peanuts be planted?

In our lives, everywhere can not see the shadow of peanuts. Peanuts have good edible value, so they are loved by people. There are also many people who grow peanuts now, but before planting, many people must want to know more about it, especially about the planting time of autumn peanuts and the time of stepping on peanuts.

When do peanuts step on seedlings?

Peanut seedling picking is generally carried out from late July to early August, and it is selected in the afternoon of sunny days. After about 15~16 o 'clock, the upright peanuts are artificially stepped on. In this way, the distance between the fruit needle and the ground can be shortened, and the fruit can be promoted; secondly, the vigorous growth of peanuts can be controlled, saving more nutrients for fruit growth; thirdly, the number of leaves receiving light can be increased after the peanuts fall to the ground, and more nutrients can be produced through photosynthesis; fourth, the root growth can be enhanced, and the cold resistance, waterlogging resistance and pest resistance of peanuts can be enhanced.

When do autumn peanuts grow?

Autumn peanuts planted in late July, according to 85 cm wide ditch ridge, ditch depth of more than 25 cm, ridge surface according to row spacing of 20 cm, hole spacing of about 18 cm double seed sowing. Select seeds before sowing, and seed them in the same depth to ensure full seedlings.

How to grow autumn peanuts

1. Apply sufficient base fertilizer. Autumn peanut planting is first to create good geographical conditions, select fertile soil, cultivate land, apply sufficient base fertilizer, and ensure the fertility of the soil.

2. Seed selection. We must choose good varieties, varieties are the basis of high yield of peanuts, we must select peanut seeds according to local climate and soil conditions, select seeds to soak and dry, improve the germination rate of seeds, and mix with seed coating before planting to repel underground pests.

3. Reasonable close planting. Autumn peanuts in sowing when the temperature is relatively high, so according to the climate for reasonable density planting, to increase the planting density of peanuts appropriately, using wide row narrow plant planting method.

4, strengthen peanut management, timely topdressing. After planting peanuts, it is necessary to strengthen the management of peanuts, timely watering, weeding and topdressing, grasp the application of nitrogen fertilizer at seedling stage, better promote the growth of peanuts, and apply foliar fertilizer appropriately at later stage to promote the root and fruit of peanuts.

5. Proper drainage. Autumn peanut early growth is the season of high temperature and rainy, and then will be accompanied by drought, to be watered with peanut each growth period.

Common Peanut Diseases and Their Control

1. Root rot. Land preparation and soil improvement, application of decomposed organic fertilizer, flood prevention and drainage, and field management. Seed dressing with 50% carbendazim wettable powder according to 0.3% of seed amount, spraying with 50% carbendazim 1000 times solution in the whole field at the initial stage of disease.

2, peanut rust. When the diseased plant rate in the field reaches 10~20%, 50% colloidal sulfur 150 times solution, or dirust sodium 600~800 times solution, or 75% chlorothalonil 800 times solution, or Bordeaux mixture 1:2:200(copper sulfate: quicklime: water), or 25% triadimefon wettable powder 3000~5000 times can be selected, sprayed once every 10 days or so, and sprayed continuously for 3~4 times. Dirust sodium should not be used continuously, but should be used alternately with other agents, spraying 60~75 kg of liquid medicine per mu each time.

3. Stem rot. 50% carbendazim WP was used to dress seeds before sowing (the dosage was 0.3~0.5% of the seed amount), or 50% carbendazim WP was used to soak seeds in water for 24 hours, and the control effect was remarkable. At the early stage of disease, spray 50% carbendazim WP or 65% manineb WP 500~600 times and 70% thiophanate-methyl WP 800 times at intervals of 7 days for 2~3 times.

Autumn peanut planting generally begins in the middle of summer each year, and peanut treading time is almost after this time. Autumn peanuts must do a good job of fertilizing and watering when planting, and then timely disease control is also very important. Only by doing this can we ensure the growth of peanuts.
