Embodiment 1

[0031] In an embodiment of the present invention, a water-saving irrigation cultivation method for corn comprises the following steps:

[0032] (1) Land selection: select contiguous plots with flat terrain, high soil fertility, and well irrigation conditions; stubble removal and land preparation can be carried out after autumn harvest or before spring sowing. When harvesting in autumn, the straw is crushed to less than 5 cm, and mechanically For hanging tillage and stubble removal, the stubble removal depth is not less than 15 cm, and the stubble length is less than 5 cm;

[0033] (2) Select improved varieties according to local conditions: use the Ludan 981 variety with good drought resistance and high yield performance;

[0034] (3) Seed treatment: Spread the purchased uncoated seeds and turn them in the sun for 1 day, and then use a plasma processor to treat them twice; then soak the treated corn seeds in the nutrient solution for 10 minutes, the nutrient The solution is c...

Embodiment 2

[0050] In an embodiment of the present invention, a water-saving irrigation cultivation method for corn comprises the following steps:

When harvesting in autumn, the straw is crushed to less than 5 cm, and mechanically For hanging tillage and stubble removal, the stubble removal depth is not less than 15 cm, and the stubble length is less than 5 cm;

[0052] (2) Select improved varieties according to local conditions: use the Ludan 984 variety with good drought resistance and high yield performance;

[0053] (3) Seed treatment: Spread the purchased uncoated seeds and turn them in the sun for 1.5 days, and then use a plasma processor to treat them twice; then soak the treated corn seeds in the nutrient solution for 15 minutes, the nutrient The solution i...

Embodiment 3

[0069] In an embodiment of the present invention, a water-saving irrigation cultivation method for corn comprises the following steps:

[0070] (1) Land selection: select contiguous plots with flat terrain, high soil fertility, and well irrigation conditions; stubble removal and land preparation can be carried out after autumn harvest or before spring sowing. When harvesting in autumn, the straw is crushed to less than 5 cm, and mechanically For hanging tillage and stubble removal, the stubble removal depth is not less than 15 cm, and the stubble length is less than 5 cm;

Abstract

The invention discloses a cultivation method of water-saving irrigation for corn. The method comprises following steps: (1) selecting lands; (2) selecting certified seeds suitable for the local condition; (3) processing seeds; (4) mounding; (5) laying drip irrigation pipes; (6) deep ploughing and conserving water with soil; (7) applying base fertilizer; (8) covering film and sowing; (9) irrigatingand topdressing; (10) reasonably close planting and economically using water; (11) enhancing field management to enhance drought resistance: (a) early thinning and final thinning; (b) intertillage for promoting root; (c) management of fertilizer and water; (d) covering with film and grass; (e) preventing and controlling disease and pests; (10) harvest. The method of the invention improves the unit yield, realizes increasing production and efficiency, and has the functions of reducing soil wind erosion, protecting the environment and improving the drought resistance and stable yield of crops;according to the growth law and nutrient requirement of maize, the planting method, fertilizer application method and field management method of maize were optimized, and the yield of maize was improved obviously.

Description

technical field [0001] The invention relates to the field of agricultural irrigation planting, in particular to a water-saving irrigation cultivation method for corn. Background technique [0002] The shortage of water resources has become an important factor restricting the sustainable development of my country's agriculture and national economy. Since the "Ninth Five-Year Plan", agricultural water conservation has developed rapidly. However, compared with the national water shortage situation, the development speed and scale of agricultural water conservation are still lagging behind. According to reports, in 1995, the lower reaches of the Yellow River were cut off and irrigation water was insufficient, which reduced grain production in Shandong Province by 2.7 million tons; the drought in 1997 caused another 20 million tons of grain loss in China, which shocked scholars at home and abroad. In order to ensure the supply of food and other agricultural products, it is nece...
