Embodiment 1
[0120] This example was demonstrated in 2015 in Xinjiang Production and Construction Corps Third Division 51 Regiment 16 Company 4# Tiaotian 116 mu of land, the first crop yielded 649.3 kg of grain per mu, the second crop yielded 5.41 tons of fresh grass per mu, and the profit per mu was 1371.5 yuan. Compared with single-cropping corn, the efficiency is increased by 34.6% to 44.3%, and the benefit is considerable, which is worthy of promotion in corresponding reclamation areas.
[0121] The specific cultivation steps are as follows:
[0122] (1) Soil selection: Select plots with smooth drainage and irrigation, deep soil layer, deep groundwater table, soil pH 7.6, soil quality above and below sandy soil, and soil organic matter above 1.1%.
[0123] (2) Variety selection: select Xinyu 69, a medium-early-maturing horse-tooth variety with a growth period of 100-105 days for the previous crop corn; choose medium-high stalk lodging resistance, density resistance and fertilizer resis...
Embodiment 2
[0148] This example was demonstrated in 2015 in Xinjiang Production and Construction Corps Third Division 51 Regiment 1 Company 2# Tiaotian 326 mu of land, the first crop yielded 601.8 kg of grain per mu, the second crop yielded 5.36 tons of fresh grass per mu, and the profit per mu was 1243.8 yuan. Compared with single-cropping corn, the efficiency is increased by 30.2% to 41.8%, and the benefit is considerable, which is worthy of promotion in corresponding reclamation areas.
[0149] The specific cultivation steps are as follows:
[0150] (1) Soil selection: Select plots with smooth drainage and irrigation, deep soil layer, deep groundwater table (below 8 meters), soil pH 7.0, medium loam soil, and more than 1.0% soil organic matter.
[0151] (2) Variety selection: Zhengdan 958, a mid-to-early-maturing half-dent variety with a growth period of 100-105 days, was selected for the previous crop corn; medium-high stalk lodging resistance (plant height 280-100 days) was selected ...

Abstract
The invention provides a grain and feed two-harvest per year corn culture method, which comprises the following culture steps of planting first crop of grain corn: selecting the corn variety before the seeding; performing land preparation seeding including base fertilizer application, land flattening and seed preparation; performing film mulching and seeding when the soil temperature in a position being 5 to 10 cm is stabilized at 10 to 12 DEG C; performing field management including seedling checking and seeding supplementation, cultivating and weeding, drip irrigation water and fertilizer management and plant diseases and insect pest prevention and control; performing harvesting; planting second crop feed corn: selecting the corn variety before the seeding; performing land preparation seeding including instant fertilization and land preparation after the harvesting of the former crop of grain corn and feed corn seeding; performing field management including final thinning, cultivating and weeding, water and fertilizer management, plant diseases and insect pest prevention and control; performing harvesting. The method provided by the invention is suitable for wide areas of south Xinjiang in Xinjiang region with the annual average temperature being higher than 10 DEG C, the accumulation temperature exceeding 4100 DEG C and the frost-free period exceeding 210 days. The method provided by the invention is suitable for large-range specified planting and has the advantages that the management is convenient; the production cost is reduced; the region light and heat resources are sufficiently used; the production efficiency and the benefits are improved; the grain and feed production can be ensured; the grain and livestock industry development can be promoted.
Description
technical field [0001] The invention relates to the technical field of agricultural crop cultivation, in particular to a method for cultivating corn with two crops a year for grain and fodder. Background technique [0002] Corn (Zea mays L.) belongs to the Poaceae Zea genus maize species, native to Mexico and Peru along the foothills of the Andes in Latin America. After Columbus discovered the American continent, he brought corn to Spain on his second return journey, and then gradually spread to all parts of the world, becoming one of the most important food crops. In my country, corn is the largest planted crop, an important source of food and feed, and has high application value. At present, with the development of animal husbandry in my country, the planting area of corn for both grain and feed is increasing year by year. [0003] Corn is one of the important food and forage crops in Xinjiang and even in the northwest oases, and plays an important role in agricultural...
