A high-yield and water-saving cultivation method of peanut under film drip irrigation

Abstract

Provided is a high-yield water-saving cultivation method for drip irrigation under a plastic film of peanuts. The high-yield water-saving cultivation method is characterized by comprising following steps: pre-sowing preparation, variety selection, sowing, pipe-laying and mulching operation, dry-seeding and wet-leaching, water control in a seedling stage, supplement of water fertilizers middle and later periods of fertility, field management and the like. The high-yield water-saving cultivation method for drip irrigation under the plastic film of peanuts has following beneficial effects: by adoption of water-saving irrigation technology featuring combination of mulched cultivation and drip irrigation, local irrigation is performed according to root distribution of crops; a soil aggregate structure is effectively maintained in order to prevent deep percolation of moisture and ground soil erosion; technical features such as heat preservation, preservation of soil moisture, decrease in soil surface evaporation and increase in utilization rate of moisture are obtained so that periodic droughts are effectively prevented from continuously happening in recent years during the peanut growth season and therefore growth of peanuts is not affected; and high-yield potential of peanuts is given into full play so that yield of peanuts is increased.

Description

technical field [0001] The invention relates to a peanut cultivation method, in particular to a high-yield and water-saving cultivation method for peanuts by drip irrigation under film. Background technique [0002] Peanut is one of the economical and oil crops that are more drought-tolerant and tolerant. The lack of regional rainfall, concentrated rainfall or seasonal drought are the main factors that limit the improvement of peanut yield and quality. Drip irrigation under mulch is a water-saving irrigation technology that combines mulch cultivation and drip irrigation. It can perform local irrigation according to the distribution of crop roots, effectively maintain the soil aggregate structure, prevent deep water leakage and surface loss, and at the same time have heat preservation and moisture conservation. And the technical characteristics of reducing surface additional issuance and improving water use efficiency. [0003] In the past peanut planting in Shandong Provinc...

Problems solved by technology

[0003] In the past peanut planting in Shandong Province, we waited for the rain to sow. This method has uncertain time and may miss the best sowing time; or we used flood irrigation or furrow irrigation after sowing in the suitable period of accumulated temperature to promote peanut germination. However, this method consumes a lot of water, has low water use efficiency and uneven irrigation

Studies have shown that peanuts are drought-resistant crops that rely on natural rainfall during the growth process without supplementary irrigation. However, in recent years, periodic droughts have occurred continuously during the peanut growing season, seriously affecting the growth of peanuts.
