[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.

Embodiment 1
[0014] (1) Preparation before sowing: plow the land after thawing in early spring, and plow to a depth of 25cm. Apply 5000kg of high-quality lap fertilizer per mu, apply pure nitrogen (N) and phosphorus (P 2 o 5 ) each 14kg, potassium (K 2 (0) 17kg, and the borax of 0.5kg is applied simultaneously, the zinc sulfate of 1kg.
[0015] (2) The drought-resistant and high-yield variety Huayu No. 22 was used as the variety, and the seeds were graded after shelling, and grade 1 seeds were selected for sowing.
[0016] (3) Sowing and laying pipes covered with film.
[0017] (4) Dry sowing and wet out: After sowing, carry out drip irrigation to promote germination and preserve seedlings, and control the amount of irrigation to 6m per mu 3 , compared with furrow irrigation to promote seedling emergence, save 10m of water per mu 3 .
[0018] (5) ， During the peanut seedling stage (from sowing to 30 days after sowing), the water-free state was kept.

[0023] (1) Preparation before sowing: plow the land after thawing in early spring, and plow to a depth of 25cm. Apply 5500kg of high-quality lap fertilizer per mu, apply pure nitrogen (N) and phosphorus (P 2 o 5 ) each 15kg, potassium (K 2 (2) 18kg, simultaneously join the borax of 0.8kg, the zinc sulfate of 1.2kg.
[0024] (2) The drought-resistant high-yield variety Huayu No. 25 was used as the variety, and the seeds were graded after shelling, and grade 1 seeds were selected for sowing.
[0025] (3) Sowing and laying pipes covered with film.
[0026] (4) Dry sowing and wet out: After sowing, drip irrigation is carried out to promote emergence and preserve seedlings, and the amount of irrigation is controlled to be 5m per acre. 3 , compared with furrow irrigation to promote emergence, save 12m water per mu 3 .
[0027] (5) During the peanut seedling stage (from sowing to 30 days after sowing), the state of non-irrigation was kept.

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...
