Generally speaking, the best time to plant peanuts is between mid-April and early May, that is, the period before and after the valley rains.

Because peanut is a temperature-loving crop, the temperature must be suitable, and the most suitable stability for peanut sowing is about 12, and the most suitable temperature for flowering is 23-28, and the lowest temperature is 19.

If you are in the south, you can plant two crops, and in spring, you can plant around the beginning of spring. If it is planted in autumn, it is planted around the time of the mango season.

Peanut cultivation method:

1) Plantar fertilizer: spring-sown peanut fields should be applied with plantar fertilizer, the specific application standard is about 2000 kg of high-quality organic fertilizer per mu, 10-15 kg of urea, 30-40 kg of superphosphate, 10-15 kg of potassium fertilizer, and supplemented by iron, calcium, boron and other trace element fertilizers.

2) Fine land preparation: After land preparation, the ground is smooth and free of squeezing, drought can be watered, and waterlogging can be drained. The peanut field covered with plastic film should be ridged, so that the ridge is straight, the ridge is flat, and the ridge width is uniform.

3) Seed treatment: Before sowing peanuts, use carbendazim of seed weight and phosphos of seed weight to control peanut seedling pests and diseases.

4) sowing spring peanuts: spring sowing mulch film covering peanuts should be purchased before sowing, and the mulch film should be made of polyethylene mulch with a thickness of millimeters and a width of 80-90 cm. From April 10th to 20th, spring sowing film covering peanuts; From April 20th to 30th, spring sowing of open-field peanuts.

The sowing density is 8000-9000 holes per mu, and each hole has 2 seeds.

5) Spray pre-bud chemical herbicides before sowing or after sowing to control weeds. Spray 50% acetochlor or 72% dol 100-150 ml per mu.

6) Check the field and protect the film: After the plastic film covers the peanut sowing and covering the film, it should be checked in the field frequently, and the plastic film is not covered tightly or is lifted or damaged by the wind, and the cover is compacted in time.

7) Open the film and release the seedlings: After the peanut top soil emerges, the film should be opened in time to prevent the seedlings from being burned.

8) Check the seedlings and replant: after the peanut seedlings emerge, check the seedlings in the field in time, and take the method of germination to replant the fields with more seedlings.

Peanuts are suitable for spring sowing, and when the temperature rises, it is conducive to peanut germination. The south can be sown earlier, and later in the north. Generally, it can be harvested in March and harvested in September.

With the method of mulching the film, sowing seeds early, as long as the temperature reaches 13 degrees, germination can be achieved. Before sowing, the peanuts are dried in the sun and then the husks are peeled. It is enough to sow three seeds per hole, with a depth of 1.5 centimeters, and it will germinate in about a week.

Later, you can weed and fertilize it, and wait for the autumn harvest of peanuts.

Spray foliar fertilizer, in order to prevent premature aging, peanut planting can be about a month before harvest, according to the growth of the plant, spray 1-2 times of urea solution plus potassium dihydrogen phosphate plus photosynthetic nutrient film fertilizer to improve photosynthesis capacity nutrients and chlorophyll to help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizer, nutrients to supply plant growth and development to the limit.

At this time, Kao 3 can be sprayed to promote the assimilation induction of plant cells to promote the transmembrane signal conversion of plant cells, forcing a large amount of nutrients to return to the top of the tip, and the inertia advantage of the tip is quickly weakened to the top situation. The main nutrients of the trunk are turned to the young fruit development system to avoid leaf hypertrophy and improve field permeability.

To treat pests and diseases, spray with a new high-lipid film in the middle and late stages of growth, once every 7 days, spray twice in a row to prevent the occurrence of diseases. When aphids occur in peanuts, targeted agents can be used for effective control.

Eating peanuts regularly has the effect of nourishing the stomach, but do you know how to grow peanuts?

Peanut bai is of course usedFish peptide du liquid calciumThe foliar surface is fattened.

Fish peptide liquid calcium leaf zhi face fertilizer.

1) Use dilute dao release 300-500 times, preferably spray.

Apply exclusively to both sides of the leaf to increase the absorption rate of the genus once every 7-10 days;

2) Watermelon, melon and other melons are the most suitable to be sprayed at the young melon stage and melon expansion stage;

3) Tomatoes, peppers, eggplants, cucumbers and other fruits, vegetables and strawberries were the most suitable to be sprayed at the flowering and fruiting stage.

4) Chinese cabbage and cabbage are the most suitable to be sprayed before the rosette stage;

5) Banana was more suitable for spraying during flower bud differentiation-bud gestation stage and after bud extraction;

6) Apple, grape, citrus, pear, peach, lychee, longan and other fruit trees have the peak of calcium absorption at the young fruit stage, and the spraying effect is the best.

How to use: 1) dilute 300-500 times, preferably spray on both sides of the leaf to improve the absorption rate once every 7-10 days;

2) Watermelon, melon and other melons are the most suitable to be sprayed at the young melon stage and melon expansion stage;

3) Tomatoes, peppers, eggplants, cucumbers and other fruits, vegetables and strawberries were the most suitable to be sprayed at the flowering and fruiting stage.

6) Apple, grape, citrus, pear, peach, lychee, longan and other fruit trees have the peak of calcium absorption at the young fruit stage, and the spraying effect is the best.

Phosphorus and potassium fertilizers. The roots of legume crops can fix nitrogen on their own, and there is little demand for nitrogen fertilizer. However, the reproduction of nitrogen-fixing bacteria requires more phosphate fertilizer, and the accumulation process of starch and oil requires more potassium fertilizer.

These two fertilizers are not easy to lose, the fertilizer effect is slow, and they are generally used as base fertilizers. In rural areas, grass ash is commonly used as seed fertilizer.

1. Seed selection. Peanuts of the current year should be selected, and the diseased grains, deflated grains, and broken grains should be eliminated when the seeds are peeled, leaving seeds with large grains, full grains, fresh color, smooth skin, and consistent shape.

2. Soaking seeds. Peanut seeds can only begin to germinate when they absorb more than 40% of their own weight. The soaking time should not be too long, in 20 warm water, soak the seeds for 12 to 20 hours. After soaking, rinse 1 2 times in clean water.

3. Germination. Peanut kernels cannot germinate at 10 o'clock, the optimal germination temperature is 25 30, and the germination rate can reach 95% after 3 4 days. When germinating, use a flat-bottomed shallow plastic mesh container or plastic seedling tray, the thickness of the seeds should not exceed 4cm, and the water should be drenched 2 or 3 times a day, so as to avoid seed overheating and rotten.

Fourth, the second germination.

After the first germination 2 3 days, the germinated seeds are selected once, the non-germinated seeds are removed, and the germinated seeds are germinated for the second time, and the suitable temperature is 20 25. The temperature is too high, although the growth is fast, but the bud body is weak and easy to age; If the temperature is too low, the growth will be slow, and the buds will rot for a long time or the cotyledons will open and leave the petals, and the quality will be poor.

5. Harvesting. During germination, the radicle first elongates and breaks through the seed coat, and at the same time, the hypocotyl also elongates upwards and thickens. The consumption standard is:

The roots are long, milky white, without bearded roots. The hypocotyl is ivory-white, long and left, thick. The seed coat is not shed, and the seed coat is peeled off, and the milky white and slightly light brown flower stripes of hypertrophic cotyledons can be seen, and under normal circumstances, 3kg of fruit buds can be produced per 1kg of seeds.

The summer production of peanut sprouts can be carried out in a shaded shelter or in a coolly ventilated room, as well as in a greenhouse or in a room with heating equipment. The cultivation frame can be made of angle iron, steel bars or bamboo and wood, and the size can be determined according to the size of the space of the production sitelayer, the spacing between the layers shall not be less than centimeters, in order to ensure the light required for the seedlings of the lower layer, the cultivation of plastic seedling trays of centimeters, the substrate can be fine sand, perlite, vermiculite, etc.

Peanut sprout cultivation technology: seed selection. The peanut kernel of peanut sprouts should be selected to produce peanuts in the current year, and the diseased grains, deflated grains, broken grains are eliminated when the seeds are shelled, leaving large grains, full grains, bright colors, smooth skin, and seeds with the same shape, generally each seed weighs about 1 gram.

Soaking. Peanut seeds can only begin to germinate when the water absorption reaches more than their own weight, so it should be ensured that there is enough water and soaking time, generally soaked in water for two hours, after soaking, the seeds are fished out, washed in clean water. Germination.

Peanut kernels can not germinate below, and the germination rate is only the optimal germination temperature - at this temperature constant temperature germinationThe germination rate can reach the plastic seedling tray when germinating, but the thickness of the seeds can not exceed cm, and the water is drenched every daySecond, it must be drenched thoroughly in order to take away the heat generated when the seeds germinate, so as to avoid overheating the seeds and produce rotten seeds.

Secondary germination. After the first germinationday, the seeds that promote the germination are selected once, remove the seeds that have not germinated, and the remaining germinated seeds are germinated twice, at this time the temperature is appropriate, and the seedling tray is put into the gram seed, and the water needs to be increased when the germination is carried out, and the water is poured - times a day, and the market can be harvested after - days.

Summary of high-yield peanut sprout cultivation and planting technology.

First, the selection of seeds Second, soaking.

3. Germination. Fourth, high-yield peanut sprout production methods and production sites and conditions.

5. Sowing 6. Management.

7. Harvesting 8. Precautions for the production of high-yield peanut sprouts.

The above are the eight most critical points of high-yield peanut sprout cultivation and planting technology. If it can really be done well, then I believe that the success rate of mass production can basically reach more than 95%. Why 95% instead of 100%?

Personally, I think that there are no absolutes in the world, and no matter how shrewd the business is, there are times when they are deceived, and sometimes accidents will occur if they are not careful, which not everyone can completely avoid.

Teach everyone peanut sprouts planting, there is a minefield for planting peanut sprouts, come and see if you don't step on it.
