How many peanuts are used in one mu of land? When do you plant it? What are the technologies?

Peanut, formerly known as Peanut, is a kind of nut which is rich in production and widely eaten in China, also known as "everlasting fruit", "muddy bean" and so on. Do you know how many peanuts are used in an acre of land? When do you plant it? What are the techniques? According to peanut grower Liu Jianhua, an acre of land needs about 10-15 kilograms of peanut seeds.

When do you grow peanuts?

Due to the different weather conditions in different regions, the cultivation techniques of peanut are different.

1. Peanuts in the south can be sown two seasons a year.

(1) when the seeds are sown in spring around March of the lunar calendar, spring peanuts bear more fruit than autumn peanuts, and the fruits are full.

(2) the sowing date of autumn peanut should be in early August at lower altitude and in late July at higher altitude. If planting on dry sloping land, it is necessary to sow early to reduce the effect of autumn drought.

2. Multi-grain varieties are mainly planted in the cold and cold and frost-free areas of the north, and more common varieties are planted in the peanut areas of the north. The suitable sowing time for large peanut areas and peanut producing areas in northern China is from late April to early May.

3. Peanut is a kind of temperature-loving crop, so the temperature must be suitable, and the most suitable stable temperature for peanut sowing is about 12 ℃, and the most suitable temperature for flowering is 23-28 ℃, and the lowest temperature is 19 ℃.

What are the peanut planting techniques?

1. Peanuts are more suitable for leveling the land.

Peanuts are cash crops that blossom on the ground, form fruit needles and drill into the ground to bear fruit. Suitable for planting on loose sandy soil and oil sandy soil. The plots for growing peanuts should be deeply turned over, combined with 30-40 tons of high-quality farm manure per hectare, and suppressed 1-2 times after turning. Where there are conditions, water can be irrigated first, and then agricultural fertilizer and chemical fertilizer can be mixed into ridges and furrows, ridging and suppression, so as to prepare for sowing at the right time. Note that peanuts like stubble, should not be repeated and welcome stubble. The better previous crops are corn, millet and sorghum.

2. Sowing method. The sowing method of peanut is sown in the open field and covered with plastic film according to the cultivation method. According to the mode of operation, it is divided into manual on demand and mechanical sowing.

3. Sowing density. It is necessary to master the principle of reasonable close planting. The planting density of peanut is determined by plant height, fruiting range and leaf area. The suitable planting density of peanut depends on climate characteristics, soil fertility, selection of varieties and cultivation conditions. Generally speaking, the plant row spacing is 5 × 8 inches, double kernel planting, sowing basic seedlings of more than 23000 per mu, harvesting seedlings of about 20, 000, CDB tries to use peanut specifications to open ploughing or peanut burrowing apparatus, six rows per row.

4. Sowing depth. In general, it is appropriate to sow peanuts about 5 cm. It is necessary to grasp the principle of "dry is not deep, wet is not shallow" and the soil should be shallow and sandy land or sandy land should be deep. The deepest cultivation in the open field should not exceed 7 cm, and the shallowest should not be less than 3 cm.

5. Suppression after broadcast. Post-sowing suppression is a successful experience of drought-resistant sowing to ensure the whole seedling of peanut. After suppression, it can not only reduce soil water evaporation, but also make seeds in close contact with soil, promote the rise of soil moisture, prevent seeds from drying, and facilitate seed germination.
