Embodiment 1

[0021] In the middle of March, flood the saline-alkali land with flood water once, with an irrigation volume of 60m3 per mu, and dry it for 1 to 1.5 months to make the surface dry enough to enter. Apply 1000kg of soil fertilizer per mu, and then rotate till once to mix the soil and fertilizer. Rake pressure to keep moisture and keep the ground level; before sowing corn, it is treated with seed coating agent. Potassium sulfate, magnesium sulfate, zinc sulfate, α-sodium naphthalene acetate growth regulator, EDTA-2Na chelating agent, humic acid, peat, fungicides, and insecticides for mixed seed dressing treatment. After 3-6 hours of boredom, mix in the fungicide, and sow the seeds immediately after the seed dressing is completed;

[0022] According to the moisture situation after flood irrigation, choose to sow in early or mid-May; the sowing rate is 1.0-2.0kg / mu; plant in a row, the width of the row is 120-140 cm, and the height of the row is about 20 cm. ~150 cm, the narrow ro...

Embodiment 2

[0025] Select the corn variety Tiantai No. 10. In the middle of March, flood the saline-alkali land with flood water once, with an irrigation volume of 100m3 per mu, and let it dry for 1 to 1.5 months. 2 times, the soil and fertilizer are mixed, the rake is pressed to keep the moisture, and the ground is leveled; before the corn is sown, it is treated with a seed coating agent. Spice powder, indole acetic acid, potassium sulfate, magnesium sulfate, zinc sulfate, α-sodium naphthalene acetate growth regulator, EDTA-2Na chelating agent, humic acid, peat, fungicides, insecticides for mixed seed dressing treatment , mix in insecticide first, mix in bactericide after pile vexed 3-6 hours, sow seeds immediately after seed dressing treatment; the actinomycetes weight part of described seed coating agent is 0.2, and described jelly-like bacillus 0.2 parts by weight, 0.2 parts by weight of the described Azospirillum, 2 parts by weight of the diatomaceous earth, 1 part by weight of the s...

Embodiment 3

[0029]Choose the corn variety Danyu 86. In the middle of March, flood the saline-alkali land with flood water once, with an irrigation volume of 100m3 per mu, and let it dry for 1 to 1.5 months. Mix soil and fertilizer, rake pressure to keep moisture, and level the ground; before sowing corn, treat it with a seed coating agent. Powder, indole acetic acid, potassium sulfate, magnesium sulfate, zinc sulfate, sodium α-naphthalene acetate growth regulator, EDTA-2Na chelating agent, humic acid, peat, fungicides, insecticides for mixed seed dressing treatment, Stir in the insecticide first, mix in the bactericide after 3-6 hours of heaping, and sow the seeds immediately after the seed dressing is completed; 0.2 parts by weight, 0.2 parts by weight of the described Azospirillum, 2 parts by weight of the diatomaceous earth, 1 part by weight of the spice powder, 0.1 parts by weight of the indole acetic acid The parts by weight of the potassium sulfate, magnesium sulfate and zinc sulfa...

Abstract

The invention discloses a cultivation method for improving corn yield in saline-alkali land. The method comprises the following steps: irrigating the saline-alkali land for flooding for once in the middle of March, wherein the irrigation volume for per mu is 60-100 m<3>, airing for 1-1.5 months until the surface of earth is dry enough to allow people to step on, applying 1000kg-1500kg of miscellaneous manure or 50kg-55kg of compound fertilizer per mu, then performing rotary tillage for 1-2 times to mix soil and the fertilizer, pressing by using a harrow and preserving soil moisture, and leveling the surface of earth; treating corn by using a seed coating agent before the corn is seeded, wherein the seed coating agent comprises actinomycin, bacillus mucilaginosus, azospirillum, diatomite, spicy powder, heteroauxin, potassium sulphate, magnesium sulfate, zinc sulfate, an alpha-pimacol growth regulator, an EDTA-2Na chelating agent, humic acid and turf; mixing bactericide and insecticide with seeds for treating the seeds, namely, firstly adding the insecticide, and then adding the bactericide after piling for 3-6 hours; and immediately seeding after the seed mixing treatment is finished.

Description

technical field [0001] The invention relates to a high-yield cultivation method for corn, in particular to a cultivation method for increasing the yield of corn in saline-alkali land. Background technique [0002] my country is a populous country, and corn is one of the three major food crops. Corn production occupies a very important position in my country's agricultural production and national economy. The development of corn production has great practical significance for increasing farmers' income, ensuring national food security and even economic security. Although the total annual production of corn in my country has developed rapidly, the total annual production of corn is insufficient, and there is still a large gap with the market demand of my country's corn, and a large amount of imports is required every year. Affected by the lack of per capita agricultural land resources in my country and the adjustment of agricultural planting structure, it is difficult to exp...
