specific Embodiment approach 1

[0037] Specific implementation mode one: the high-yielding cultivation method of corn in the dry farming area of ​​the northern cold region of the present implementation mode is carried out according to the following steps:

[0038] 1. Subsoiling the soil and applying basal fertilizer

[0039] Select the 2nd to 4th accumulated temperature zones in the division of climate zones in Heilongjiang Province in the black soil region of Northeast China, that is, within the range of north latitude 46°01′~48°30′, east longitude 123°15′~133°30′, near the water source, front The stubble is the land of soybeans, wheat and flax, and the land is subsoiled by 25 cm to 30 cm before freezing in autumn, and then the subsoiled land is applied with 12 to 15 tons of base fertilizer per hectare; the base fertilizer is decomposed organic fertilizer;

[0040] Second, change the ridge

[0041] Change the traditional small ridge with a width of 65cm to a large ridge with a width of 130cm, and then trim...

specific Embodiment approach 2

[0064] Embodiment 2: This embodiment is different from Embodiment 1 in that: the cooked organic fertilizer described in Step 1 is decomposed cow dung. Other steps and parameters are the same as those in the first embodiment.

[0065] step

specific Embodiment approach 3

[0066] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that: the width of the coated film described in Step 5 is 140cm-150cm. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a high-yield cultivating method for corn, in particular to a high-yield cultivating method for corn in the dry-farming area of a northern cold region. The method aims at solving the problem that in the dry-farming area of the northern cold region in China, accumulated temperature is insufficient, spatial and temporal distribution of rainfall is uneven, and consequently, the yield of the corn is low. The method comprises the steps that 1, deep scarification, soil preparation and base fertilizer applying are carried out; 2, ridge changing is carried out; 3, seeding is carried out; 4, fertilizer is applied; 5, drip irrigation equipment is mounted, and film mulching and film breaking are carried out; 6, regulated deficit irrigation is carried out; 7, first-stage chemical treatment is carried out; 8, second-stage chemical treatment is carried out. Compared with a local traditional method, according to the method, the yield of the planted corn is increased by 50% to 100%, good reproducibility is achieved, and popularization is easy. The method is used for cultivating the high-yield corn in the dry-farming area of the northern cold region.

Description

technical field [0001] The invention relates to a high-yield cultivation method for maize in the dry farming area of ​​the northern cold region. Background technique [0002] There is only one earth in the world, and agricultural water resources are limited after all; with climate change, the degradation of cultivated land is showing aggravating trend; moreover, as the world population continues to increase and the global economy continues to develop rapidly, the demand for food will inevitably increase year by year, so , Relying on science and technology to increase grain yield per unit area and ensuring food security has always been the basic strategy for agricultural development in all countries in the world. [0003] my country has a large population, relatively poor agricultural land and water resources, the national economy has been developing rapidly, and the contradiction between man and land is very prominent; Premier Wen Jiabao pointed out in the government work re...
