Problems solved by technology

[0004] In recent years, the use of no-tillage seeders has been promoted for no-tillage sowing under conditions of corn stalk stubble and a small amount of straw mulch, which has reduced the burning of corn stalks. Due to farming problems, it is difficult to ensure the quality of sowing. However, straw baling and other methods for straw removal from the

Embodiment 1

[0029] A no-tillage operation method for full-scale collection of straw and mulching, which takes two years as a cycle, including the first year and the second year of implementation.

[0030] The first year of implementation includes the following steps:

[0031] Step 1. Land plot selection: Suitable for mechanized operation areas, the cultivated soil layer is greater than 40 cm, the land slope is less than 10°, and the cultivated layer has no obstacles such as stones and tree roots.

[0032] Step 2. Straw treatment: use 4-row corn harvesters such as John Deere and Bravery to harvest corn, turn the straw returning machine on the corn harvester, crush the corn stalks in the harvested field into about 10 cm, and sprinkle them on the cultivated land surface.

[0033] Step 3. Straw collection: In autumn, use 40-60 horsepower tractors to hang rear-mounted 2-row or 4-row straw collection machines and other equipment to clean and collect the corn stalks scattered on the ground to f...

Embodiment 2

[0041] A no-tillage operation method for covering rows with full amount of straw, with a cycle of two years, including the first year and the second year of implementation.

[0042] The first year of implementation includes the following steps:

[0043] Step 1. Land plot selection: Suitable for mechanized operation areas, the cultivated soil layer is greater than 40 cm, the land slope is less than 10°, and the cultivated layer has no obstacles such as stones and tree roots.

[0044] Step 2. Straw treatment: If it is harvested manually, the corn stalks stand in the field, and the 904 tractor can be used to hang a separate straw returning machine to crush all the straws standing centimeters in the field into about 10 centimeters and sprinkle them on the surface of the cultivated land.

[0045] Step 3 + Step 4, Straw collection + autumn subsoiling: use 604 or 704 tractors, hang 2 rows of straw collection machines in front of the tractor, and hang 2 rows of subsoilers at the back ...

Abstract

The invention discloses a total collecting and covering no-tillage operation method for corn straw, and belongs to the field of agriculture. The total collecting and covering no-tillage operation method comprises the steps of step 1, selecting land blocks; step 2, treating straw; step 3, collecting straw in rows; step 4, performing deep scarification in autumn; step 5, performing no-tillage sowing; step 6, performing reduced application of herbicides; step7, performing deep scarification at the seedling stage; and step 8, managing diseases and insect pests, so as to form a crop rotation mode for alternative operations in two years for a straw mulching leisure zone and an agrarian zone. According to the total collecting and covering no-tillage operation method, the problem between total straw returning to fields and sowing can be effectively solved, the rate that the protective cultivation straw is returned to the fields is increased to 100%, the method has obvious operations for preservation of soil moisture for north in spring, the sowing effect and the rate of emergence are guaranteed, the yield increment effect is obvious, straw returning to fields can protect the black lands, and the method is a strong measure for constructing agricultural sustainable development.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a no-tillage operation method for covering all rows of straw. Background technique [0002] At present, the processing method of corn planting technology is to return a small amount of straw to the field and burn a large amount of straw. This method seriously pollutes the environment, resulting in soil compaction and a decrease in microbial content. A large number of agricultural crop resources are not fully utilized. [0003] Crop straw contains a large amount of organic matter such as cellulose, hemicellulose, and protein, as well as mineral elements such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and is one of the important fertilizer sources for agricultural production. Returning crop stalks as fertilizer can effectively increase the content of soil organic matter, improve soil, and improve soil fertility. It is especially important for ...
