High-yield peanut cultivation method for relieving successive cropping obstacle

Abstract

The invention discloses a high-yield peanut cultivation method for relieving successive cropping obstacle. The high-yield peanut cultivation method for relieving successive cropping obstacle comprisesthe following steps: (1) soil preparation: laying lime nitrogen and dazomet, and ploughing; (2) ridging and film mulching: laying trickle irrigation tubes while film mulching; (3) trickle irrigation:controlling water to permeate into the soil with the depth being 20 cm or above; (4) seeding hole forming: forming seeding holes in films to release toxic gas; (5) seeding: carrying out trickle irrigation through the trickle irrigation tubes in time after seeding, and during trickle irrigation, dropwise adding liquid peanut nitragin along with water; and (6) trickle irrigation and bacterial supplementing: carrying out trickle irrigation in a peanut four-leaf stage, and dropwise adding a compound microbial additive along with water for supplementing beneficial bacteria. The soil sterilizing effect is improved, the beneficial bacteria are supplemented, irrigation can be implemented as required, successive cropping obstacle can be relieved effectively, and growth and development of peanuts are promoted. The heights of stems of the peanuts are increased by 8.4%-25.6%, the branching number is increased by 4.1%-19.4%, the number of fruits of a single plant is increased by 3.1%-17.7%, the weight of one hundred peanuts is increased by 6.0%-11.9%, the full fruit rate is increased by 3.6%-7.3%, and the yield of legume is increased by 8.1%-28.9%.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield cultivation method for peanuts that removes continuous cropping obstacles. Background technique [0002] Peanut is a sensitive crop to continuous cropping. Continuous cropping peanuts have slow growth, short plants, low yield and poor quality. Generally speaking, the production of peanuts will be reduced by 3% to 5% for one year of continuous cropping, 5% to 10% for two consecutive years, 10% to 15% for three years, 20% for four years, and 5 years or more. Yields are consistently low. my country has a large peanut area and relatively concentrated production areas. Continuous cropping is one of the main factors leading to low and unstable peanut production. For example, the annual peanut continuous cropping area in Shandong is about 7 million mu, accounting for more than 60% of the peanut planting area, which directly affects the continuou...

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a high-yield cultivation method for peanuts that removes continuous cropping obstacles, eliminates soil harmful organisms, supplements beneficial microorganisms, and solves conventional methods Fumigation "killing" is not thorough, beneficial microorganisms are not strong due to the interference of soil indigenous microorganisms, and the effect is poor
