Twelve methods for High yield of Peanut

Do not underestimate this small peanut, in fact, it contains a lot of nutritional value, peanuts, whether boiled or stewed, or made into a variety of small snacks are very sweet and delicious, and peanuts can also be fried peanut oil, pure peanut oil is also loved by everyone.

Twelve methods for High yield of Peanut

First, fine fertilization. The one-time fertilization method was used to apply base fertilizer, 1000 kg of rotten manure, 50 kg of peanut special compound fertilizer or 75 kg of peanut special compound fertilizer, 40-50 kg of calcium superphosphate, 10 kg of potassium chloride and 1 kg of borax were applied uniformly before ploughing.

Second, skillfully control seedlings. 40-50 days after the beginning of flowering, that is, the early podding stage of peanuts. When the plant grows to 30 cm, 70-100mg / L ppm aqueous solution should be sprayed on the leaves in time, and 50-75 liters of available liquid per mu. It can dwarf peanut plants and prevent overgrowth and lodging. If the growth is still too exuberant after spraying, it can be sprayed again every 10 days or so to ensure that the plant height is 30-40 cm.

Third, spraying leaf fertilizer. Extra-root topdressing can be foliar sprayed with 1% urea solution and 2% Mel 3% superphosphate 1-2 times after podding stage, or 50 grams of ammonium molybdate per mu, 50 kg of water, and then sprayed again 10 days later.

Fourth, skillfully apply calcium fertilizer. Peanut needs a large amount of calcium, which is more than phosphorus and close to potassium, especially in the fruiting stage. The application of gypsum in calcium-deficient or sulfur-deficient soil is beneficial to the formation of peanut shell and improve the fruit rate.

Fifth, apply micro-fertilizer skillfully. Although peanut has little demand for boron and molybdenum, it has a great influence. In the seedling stage and flowering stage, the leaf surface is sprayed once with 50 kg of 0.2% borax solution per mu; during the growing period, the leaf surface is sprayed with 0.1% Mu 0.2% ammonium molybdate solution 50 kg per mu, and the yield can reach 20% per mu.

6. Pruning. When peanuts begin to have buds, cut off diseased branches and non-flowering upward branches with scissors. When cutting non-flowering branches, leave 3-4 branches per litter of short branches and leaves, and 2-3 branches per litter of tall branches and leaves, so as to achieve the purpose of fullness of fruit.

7. Remove the main stem. The top advantage of peanut is very prominent, the effect of increasing yield by removing the main stem after 10 days of flowering is obvious, and the yield can be increased by about 15% per mu, but the effect of early or too late removal is not significant.

8. Peanuts step on rice seedlings. In the peak growing season of peanuts, the measures of artificial stepping on seedlings can control up and down, promote the fruit needle to be tied down, increase the effective number of single hole by 3-5, and increase the yield by 20%. The method is: generally from late July to mid-August, after 3 pm on a sunny day, step down the upright peanut seedlings with your feet, shorten the distance between the fruit needle and the ground, and promote the fruit needle to enter the soil early to achieve the goal of increasing fruit income.

9. Dig the earth and bury the fruit. When a large number of peanut fruit needles enter the soil, some of the fruit needles are difficult to get into the soil. If you first hoe the peanut rows with a hoe, and then use the hand to pick the soil around the fruit seedlings to bury the fruit, this can improve the fruit needle penetration rate and fruit rate, and generally increase the yield by about 15% per mu.

Ten, the whole plant ring. The pressing ring of the whole plant in the full flowering stage of peanut can improve the crowded condition among plants in the hole, make full use of space and light energy, shorten the distance between the fruit needle and the ground, expand the fruit range, and help the fruit needle to tie the soil early, bear more fruit and bear full fruit. The method is to press the circle in full bloom, weave the wicker with a diameter of 30-35 cm into a circle and press it on the central part of the three peanut seedlings, so that each hole of peanut accounts for 1 inch 3, so that the stem branches can crawl on the ground as far as possible.

11. Pick your heart at the right time. Timely coring of peanut can effectively inhibit apical dominance and promote the elongation and fruiting of the second pair of lateral branches. After the main stem of peanut is removed, the yield can be increased by about 10%. During the heart-picking period of peanuts, it is better to carry out from the initial flowering stage to before the full flowering stage.

Note:

1. When picking the heart, the cut should be flat:

2. The top taken off should be taken out of the field for fodder or retting fertilizer.

3. After coring, a small amount of nitrogen and phosphorus fertilizer can be applied according to the seedling condition to promote branch growth.

4. The weak field is not suitable to pick the heart.

Prevention and control of diseases and insect pests.

1. Red spider. The damage period of red spider is from June to August and is rampant in dry years. Spray control can be made of 1.8% avermectin EC 3000 times, 15% daben EC 1000-1500 times, 40% diclofenac 1500-2000 times and so on.

2. Aphids. Aphids are the main pests that harm peanut leaves, causing leaves to curl up and grow poorly. At the same time, aphids can also spread a variety of viral diseases. Therefore, 10% imidacloprid wettable powder 5000 times solution can be selected to control aphids.

3. Grubs. It is an underground pest, which affects peanut germination, fruit setting, pod setting, yield and quality, and can be harmful in the whole growth and development period. To control grubs, the following methods can be taken to control grubs: 1. Larval stage: spread evenly around the peanut pier with 40% Lesbon EC 0.25 kg / mu, 40% phoxim EC 0.25 kg / mu, and soil 20 kg / mu. 2. Adult stage: take 3-5 branches of fresh elm, poplar and willow 60 cm long and tie them into a handful, soak them in 75% phoxim EC 50 times or 45% phoxim EC 50 times solution for 5 hours for 6 hours, then insert them in the field in the evening, 10-15 traps per mu; 3. Catch adults manually: using flashlights every evening to capture adults on poplar, elm, willow, Robinia pseudoacacia and other trees near the peanut field. Feeding the captured adults to poultry or centralized treatment can not only reduce the source of insects, but also ensure that the leaves of trees will not be damaged.

4. Beet armyworm. According to the living habits of beet armyworm, the best period for chemical control should be the peak period of egg hatching and the peak period of 1-2-year-old larvae, the time of application should be in the morning and evening, and the front and back of peanut leaves should be applied evenly. You can choose 5% flufenuron EC, 5% Nongmont EC, 5% fluomuron EC, 5% diflubenzuron EC, and spray control with its 1500-2000-fold solution in the field. 10% suspension 1500-2000-fold solution, 2.5% Kung Fu 2000-fold EC, 4.5% permethrin EC 1500-2000 times, and so on.

Technology of increasing yield of Peanut

1. Foliar fertilizer spraying to prevent premature senility. Foliar fertilizer spraying on peanuts has many advantages, such as low cost, quick effect and easy operation. In order to prevent premature senility, about a month before harvest, spray 1% 2% urea solution and 0.4% potassium dihydrogen phosphate according to the plant growth, usually spray twice, at an interval of about 10 days.

2. Spraying hormone to control the growth. In the peanut fields with high soil fertility and good water and fertilizer conditions, hormone spraying can be scientifically controlled under the guidance of agricultural technicians.

3. Effective application of pesticides to control insect pests. The main disease of peanut is leaf spot, which occurs more and more seriously in rainy season. Generally, in the middle and later stages of growth, 40% carbendazim 600 times, 50% mancozeb 500 times, once every 7 days, twice in a row. The main pests of peanuts are aphids and grubs. Organophosphorus or pyrethroid pesticides can be used to control aphids. Grubs can be irrigated with 500 × 700 times of phoxim, and the effect is better before rain.

Planting Prospect of Peanut

Peanut is an important oil crop, cash crop and export agricultural product in China. Based on the summary and analysis of the current situation of production, processing and export trade of China's peanut industry, the main problems existing in the development of China's peanut industry are put forward, and according to the current situation, the development prospect of China's peanut industry is prospected.

China is also the largest consumer and exporter of peanuts. Peanut production in China has a wide range of areas, except Xizang, Qinghai, Ningxia, Hong Kong and other provinces. It is mainly concentrated in the northern North China Plain, the coastal areas of Bohai Bay, the coastal areas of South China and the Sichuan Basin. It can be divided into two major producing areas, namely, the northern production area and the southern production area. The area and total output of the northern peanut production area account for 60% and 65% of the country respectively. Peanut cultivation in China is mainly in Shandong, Henan, Hebei, Guangdong, Sichuan, Jiangsu, Anhui and other provinces. The peanut area accounts for 72% of the country, and the total output accounts for 79% of the country. Henan and Shandong are the largest provinces, and the total peanut planting area of the two provinces accounts for about 45% of the country's total.

Although growing peanuts seems to be a relatively simple thing, if you want to do it well, you still need to pay attention to a lot of skills if you want to grow high-yield peanuts. First of all, you have to understand the growth habits of peanuts. Reasonable fertilization, pruning, and so on, can increase the yield of peanuts and obtain higher profits.
