Several measures to promote peanut yield

After the peanuts emerged from the seedlings, the soil at the base of the seedlings was opened and the two cotyledons were exposed to the ground. In this way, the first side of the peanut can be early, the internodes of the stem are shortened, the seedlings are strong, and the early flower buds are differentiated, which is conducive to high yield. According to local experiments, it is generally 10% to 20% more than the unclear seedlings . Clearing the tree must master the time and depth. The time is in the basic Qimiao, the main stem can be seen when two true leaves are visible, the seedlings are too early, and the resistance to the external environment is weak; the too late side branches can not reach the purpose of clearing the tree. The depth is determined by the two cotyledons exposed to the soil surface. The first pair of lateral branches are still buried in the soil, which can not be used for clearing the trees; if it is too deep, the embryos will be easily removed, causing the seedlings to fall, which is not conducive to growth and development. After 15 days of clearing the tree, the soil can be ploughed.

 

The whole planting ring is combined with the sorghum to clear the tree at the beginning flowering stage, and the soil (preferably wet soil) is pressed on the base of the peanut stalk, so that each nest of peanut mites faces three directions, so that the peanuts are inclined to the surface to grow. Before and after the peanut sealing and starting flowering period, a circle with a diameter of about 30 cm is used to press the central part of each nest of peanuts to make it grow on the ground in three different directions. In this way, the disease can be reduced compared to conventional cultivation. Branches grow well and the range of results increases. Generally, peanuts can be increased by 10% to 15% .

 

Timely sprinkling peanuts When a large number of fruit needles enter the soil, some fruit needles can not enter the soil, and some fruit needles stop growing when they touch the soil. At this critical moment, the fine soil is scattered from the top, which can be improved. Fruit needle placement rate, fruit setting rate and fruit filling rate. According to the test, the peanuts are sprinkled in time after the flowering period, and the yield can be increased by more than 5 kg per mu .

 

Chasing calcium fertilizer requires a lot of calcium and phosphorus during the fruiting period. Superphosphate helps the formation of the shell, increases the fruit filling rate, and increases the seed oil content. Foliar application with 2% superphosphate solution is better.

 

The practice of increasing the application of boron fertilizer and molybdenum fertilizer proves that the application of boron fertilizer and molybdenum fertilizer can generally increase yield by more than 10% . Method of administration: 0.3% borax solution 50 to 60 kg in the early flowering foliar spraying mu, mu growth of 0.15% ammonium molybdate solution 50 kg foliar spray. Disease prevention: In the middle and late stages of peanut growth, it is most susceptible to leaf spot disease and flower rust disease. It should be applied once every 7 days in the middle of the needle , sprayed with sprayed leaf fertilization and carbendazim to control leaf spot disease and flower rust disease.
