Peanut seed price and planting method

Peanut is a kind of widely edible nut, also known as peanut, evergreen fruit, muddy bean, etc. it is an annual herb of the genus Peanut of Leguminosae, with rich root nodules and erect or creeping stems. It is widely cultivated in various parts of our country. It is suitable for sandy soil areas with warm climate and moderate rainfall, and the growing season is longer. Let's take a look at the seed price and planting methods of peanuts.

How much is the peanut seed per jin?

The price of peanut seeds is about 810 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of peanut seeds. Peanut cultivation is very common in China, usually one mu of land needs about 20 jin of peanut seeds, one thousand holes per mu, two to three grains per mu, the yield per mu is about 600 jin, and the high-yield field can be close to 800 jin.

What kinds of peanuts do you have?

1. Common type: the pod shell is thick, the vein is smooth, the pod is cocoon-like, there is no keel, and most of the seeds are oval, which is the main cultivated variety in our country.

2. Bee waist type: the pod shell is very thin, the vein is prominent, there are keels, there are more than three seeds, sometimes there are two grains, and the seed coat is dull and dull.

3. Multi-grain type: there are many seeds in the pod, showing a string of beads, the shell is thick, the vein is smooth, the seed coat is red, sometimes white.

4. Pearl type: the pod shell is thin, the pod is small, generally two seeds, the kernel rate is high, the seeds are full, most of them are pick-shaped, and the seed coat is mostly white.

Sowing method of Peanut

1. Sowing time: the optimum temperature for peanut flowering is 23: 28 ℃, the lowest temperature is 19 ℃, the optimum temperature for pod setting is 25: 30 ℃, and the lowest temperature is 15 ℃. Sowing time should be arranged reasonably according to local air temperature and local sowing habits, and suitable sowing time is beneficial to high yield.

2. Sowing method: the sowing method of peanut is sown in the open field and covered with plastic film according to the cultivation method, and the planting density is determined by plant height, fruiting range and leaf area. planting density depends on climate characteristics, soil fertility, selection of varieties and cultivation conditions.

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

4. Post-sowing suppression: peanut post-sowing suppression is an effective way to resist drought and sow peanuts to ensure the whole seedling. Suppression can not only reduce soil water evaporation, but also make seeds in close contact with the soil, promote the rise of soil moisture and prevent drying. It is easy for seedlings to germinate.

Planting methods of Peanut

1. Check seedlings and replenish seedlings: peanut seedlings should be checked in time after emergence, and seedlings should be replenished in time where there is a serious shortage of seedlings, so that the number of seedlings per unit area can reach the planned number, which is generally carried out 3-5 days after emergence.

2. Clear and strong seedlings: when peanut seedlings are ploughed for the first time, peanut seedlings are ploughed with a small hoe to strip the soil around the peanut seedlings, so that two cotyledons and the first pair of lateral branches are exposed to the soil, so that the first pair of lateral branches can develop healthily and make the seedlings grow vigorously.

3. Irrigation and drainage: peanuts are afraid of both drought and waterlogging. The irrigation period is mainly determined by the amount and distribution of precipitation during the peanut growth period, soil water content and the need for soil moisture at each growth stage of peanut.

4. Moderate prevention and control: about 30 days after flowering, in order to prevent the overgrowth of the plant, when the plant grows too much and the field is closed prematurely, the foliar spraying of paclobutrazol can increase the yield by 10%.

5. Disease and pest control: peanuts are susceptible to leaf spot disease and peanut rust. Leaf spot disease uses 75% topiramate 1000 times or 50% carbendazim 800 × 1000 times 70 kg 80 kg per mu, and peanut rust uses 20% trimethoprim EC 30 ml to 40 kg water per mu.
