Embodiment 1

[0020] A light, simplified and high-efficiency intercropping pattern of corn and green manure of the present invention comprises the following steps:

[0021] S1. Set up the field structure in early spring, the width of corn is 110cm, the width of arrowhead pea is 70cm, and the distance between crops is 23cm;

[0022] S2, sowing arrowhead peas after covering, planting 4 rows in each zone, row spacing 18cm, hole spacing 24cm, 5-7 seeds in each hole, and planting corn after arrowhead pea seedlings are complete, planting 3 rows in each zone, row spacing 40cm, The distance between plants is 21cm, and one seed is planted in each hole;

[0023] S3. Use 50ml of 72% 2,4-D butyl EC at the flowering stage of arrowhead peas, mix with 35kg of water, spray evenly to kill and cover the ground on the spot, wait for the stems and leaves at the bottom to decompose slowly, release nutrients, and use the ground to cover at the same time Inhibit evaporation and reduce temperature, reduce water l...

Embodiment 2

[0032]The steps of Example 2 and Example 1 corn and green manure light simplified high-efficiency intercropping mode are the same, the only difference is that in S1, the width of corn is 105 cm, the width of arrow pea is 68 cm, and the distance between crops is 21 cm; Plant 4 rows with a row spacing of 17 cm and a hole spacing of 23 cm. Plant 5 seeds in each hole. After the arrowhead pea seedlings are ready, sow corn. Plant 3 rows in each row with a row spacing of 38 cm and a plant spacing of 20 cm. Plant 1 seed in each hole.

[0033] Among them, in S1, the basal fertilizer was applied before the field deployment, and the arrowhead pea was applied with 88kg / hm of pure nitrogen 2 , pure phosphorus 43kg / hm 2 ; Apply pure nitrogen 80kg / hm to corn 2 , pure phosphorus 133kg / hm 2 .

[0034] All the other are identical with embodiment 1.

Embodiment 3

[0036] The steps of Example 3 and Example 1 corn and green manure light simplified high-efficiency intercropping mode are the same, the only difference is that in S1, the width of corn is 115 cm, the width of arrow pea is 72 cm, and the distance between crops is 25 cm; Plant 4 rows with a row spacing of 19 cm and a hole spacing of 25 cm. Plant 7 seeds in each hole. After the arrowhead pea seedlings are ready, sow corn. Plant 3 rows in each row with a row spacing of 42 cm and a plant spacing of 22 cm. Plant 2 seeds in each hole.

[0037] Among them, in S1, the basal fertilizer was applied before the field deployment, and the arrowhead pea was applied with 92kg / hm of pure nitrogen 2 , pure phosphorus 47kg / hm 2 ; Apply pure nitrogen 82kg / hm to corn 2 , pure phosphorus 137kg / hm 2 .

[0038] All the other are identical with embodiment 1.

[0039] The following will be described in detail in conjunction with specific embodiment 1.

[0040] The invention provides a light, simpli...

Abstract

The invention relates to the technical field of the agriculture planting, more specifically to a corn and green manure light-simplified efficient intercropping mode. The mode comprises the following steps: S1, laying a field structure at early spring, wherein the corn zone width is 105-115cm, the common vetch zone width is 68-72cm, and the crop spacing is 21-24cm; S2, seeding the common vetch after film mulching, seeding four lines at each zone, wherein the line spacing is 17-19cm and the hill spacing is 23-25cm, and seeding for 5-7 grains at each hill; seeding the corn after completely seeding the common vetch seedlings, seeding three lines at each zone, wherein the line spacing is 38-42cm and the row spacing is 20-22cm, and seeding 1-2 grains at each hill; S3, applying 50ml of 2,4-D butyl ester missible oil in volume fraction of 72% at the full-bloom stage of the common vetch, mixing with 35kg of water, uniformly spraying, and covering on the earth surface in place after killing; S4,ploughing the common vetch into soil as green manure at the autumn ploughing; and S5, performing shifting cultivation on the corn zone and the common vetch zone at the second year. Through the efficient intercropping mode disclosed by the invention, the growth period inter-zone nutrient transfer and next-year inter-zone crop rotation are utilized, and the problem that the dependency on the chemical nitrogenous fertilizer in the corn traditional production can be solved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a light, simplified and high-efficiency intercropping mode of corn and green manure. Background technique [0002] Corn is the largest food crop in my country and even in the world, and its high-yield characteristics play an important role in solving food security problems. However, the year-by-year decrease of arable land area and the continuous increase of food demand make the amount of chemical fertilizers used in corn production remain high, but the large-scale use of chemical fertilizers has not continued to increase corn production, but has caused serious ecological and environmental problems, such as soil degradation, groundwater Negative environmental effects such as pollution and greenhouse gas emissions have put corn production under unprecedented pressure. Seeking green input has become an important way to ensure high yield and high efficiency of corn. ...
