Embodiment 1
[0025] Location: Dongwangzhuang Village, Shuibosi Township, Datong City, Shanxi Province, with an altitude of 1050m, an annual average rainfall of 370-460mm, and an evaporation rate of 1876mm. The strong evaporation period is in spring and autumn, with an annual average temperature of 7.0°C and a frost-free period of 138 days.
[0027] 2. Sowing field preparation: Autumn plowing, the plowing depth is 18-25cm, timely harrowing after plowing, the plowing stubble is well buried, the ground is flat, and there is no missing plowing and no rubbish. Autumn plowing is carried out every other year. In the year when the land is not plowed, use a tractor with a tiller to remove stubble.
[0028] 3. Sowing method: single seed sowing.
[0029] 4. Seeding rate: The suitable density is 3500-4000 plants / mu.
[0030] 5. Fertilization amount: 3.40kg of pure nitrogen, 1.25kg of phosphorus, and 2.30kg of ...

Abstract
The invention discloses a mechanized high-yielding efficient cultivation method for spring maize. According to the method, a one-change, two-improvement, two-increase, three-prevention and two-timely new technology is adopted; one-change means changing a planting method, and the original precision sowing is changed to single-grain sowing; two-improvement means improving land preparation quality and sowing quality so as to achieve no land missing, no clod, good ploughed stubble digging and burying, flat ground surface, proper-soil-moisture sowing, consistent seed level, no reseeding and no seeding absence; two-increase means reasonably increasing density and reasonably increasing a fertilizing amount; three-prevention means disease prevention, insect prevention and weed prevention, the disease prevention adopts an integrated control technique which is based on selecting a disease resistant variety, gives priority to chemical control and is assisted by agricultural health-care measures; for insect pests, the insect prevention is superior to insect elimination, so that early prevention and early elimination should be carried out; field weed control mainly comprises two critical periods, i.e., before seedling emergence and after seedling emergence, i.e., carrying out soil sealing before seedling emergence and carrying out stem and leaf treatment after seedling emergence; and two-timely means timely intertillage and timely harvesting. The yield of the maize is increased greatly.
Description
technical field [0001] The invention relates to the field of corn cultivation, in particular to a mechanized high-yield and high-efficiency cultivation method for spring corn. 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 expand the ...
