Problems solved by technology

[0002] In wheat-corn annual production, there are common problems such as excessive wheat stubble and improper straw treatment, which lead to low corn seeding quality and emergence rate, poor seedling uniformity, poor seed fertilizer isolation, and premature aging after defertilization in the later stage, which seriously affect the high yield of corn. efficient production

Embodiment

[0027] Example: such as Figure 1-5 As shown, the present invention is a planting method to achieve summer maize dense planting yield increase, comprising the following steps:

[0028] Step 1: Pretreatment: Harvest the wheat, and crush the wheat straw, and spread the wheat straw evenly in the corn planting field;

[0029] Step 2: Seed selection: use maize varieties with suitable ripening period, sow early in time, improve the quality of sowing, and adapt to local conditions;

[0030] Step 3: Sowing: Use the isotop profiled corn no-till precision seeder for sowing, and set up a number of tillage bins between the sowing rows, and each tillage bin corresponds to the front and back positions of the seeder;

[0031] Step 4: Fertilization: Using the precision co-sowing technology of seed fertilizer, 50% of the total nitrogen fertilizer and all phosphorus, potassium and zinc sulfate are applied as seed fertilizers, and irrigated 1 to 2 times, each time is 750 cubic meters / hm 2 , the remai...

Abstract

The invention discloses a planting method for realizing close planting and yield increase of summer corn, which comprises the following steps: step 1, pretreatment: harvesting wheat, crushing wheat straws, and uniformly spreading the wheat straws in a corn planting field; 2, seed selection: using a corn variety with a proper ripening period, early sowing in time, improving the sowing quality, and adjusting measures to local conditions; step 3, sowing: sowing by adopting an in-situ profiling corn no-tillage precision sowing machine, arranging a plurality of tillage bins between sowing rows, and arranging each tillage bin corresponding to the front and rear positions of the sowing machine. According to the planting method for realizing close planting and yield increasing of summer corn, a'in-situ profiling and air suction precision seeding 'technology and a'seedling strip arrangement and deep scarification fertilization' compound operation technology are adopted, and precise information regulation and control are assisted, so that precise regulation and control of seeding depth, single-grain precise seeding and layered deep fertilization are completed, and row spacing, seeding depth and fertilization depth are consistent.

Description

Technical field [0001] The present invention relates to the field of summer corn planting technology, specifically a planting method to achieve summer corn dense planting yield increase. Background [0002] In the annual production of wheat-corn, there are widespread problems such as high wheat stubble retention, inadequate straw treatment, resulting in low corn sowing quality and seedling emergence rate, poor seedling neatness, poor seed fertilizer isolation, and early aging of late defertilization, which seriously affects the high yield and efficient production of corn. Therefore, we have improved this and proposed a planting method to achieve increased yield of summer maize dense planting. Contents of the Invention [0003] In order to solve the above technical problems, the present invention provides the following technical solutions: [0004] The present invention is a planting method to achieve summer maize dense planting yield increase, comprising the following steps: [...
