Problems solved by technology

[0008] So far, under dense planting conditions, there has been no breakthrough in planting methods that not only ensure the stable yield per unit area of ​​wheat, but also take into account the triple effects of steam reduction, water saving, and weed control by mulching with plastic film.

example 1

[0015] Example 1: Take winter wheat cultivation as an example. Before sowing, fill the soil moisture and apply sufficient soil fertilizer, turn tillage and rotary tillage after the moisture content, and mix the soil and fertilizer evenly; use selected winter wheat seeds, sow at a depth of 2cm, level the soil surface after sowing, and make a field with a width of 8m and a length of 10m. Then cover the white degradable microfilm with a thickness of 0.004mm and a width of 2m; the film is evenly covered with a layer of soil with a particle size of less than 1cm and a thickness of 2cm. There are no overlaps and no gaps. Before emergence, the covering soil on the membrane will crust when it rains, and it will be suppressed to break the compaction. During the jointing stage of the wheat, 60mm of water was poured, and nitrogen fertilizer was applied appropriately in combination with the water.

example 2

[0016] Example 2: Take winter wheat cultivation as an example. Before sowing, irrigate enough soil moisture, apply sufficient soil fertilizer, and directly rotate tillage after the soil moisture, and mix the soil and fertilizer evenly; use selected winter wheat seeds, sow at a depth of 2cm, level the soil surface after sowing, and make a furrow with a width of 8m and a length of 10m; Then cover a black degradable film with a thickness of 0.006mm, a carbon black content of 3%, and a width of 1m; the film is evenly covered with a layer of soil with a particle size of less than 1cm and a thickness of 1cm. The film and the topsoil under the film are tightly combined without overhead. There is no overlap and no gap between the sheets of mulch. There was no precipitation before emergence, and the precipitation was 80mm in spring, and there was no irrigation and no topdressing.

example 3

[0017] Example 3: Take spring wheat cultivation as an example. Before sowing, apply enough base fertilizer, and directly rotate till after mixing the soil and fertilizer, mix the soil and fertilizer evenly, and sow with appropriate moisture after rain; use selected spring wheat seeds, sow at a depth of 2cm, level the soil surface after sowing, and make a field with a width of 8m and a length of 10m. Then cover the white degradable microfilm with a thickness of 0.004mm and a width of 2m; the film is evenly covered with a layer of soil with a particle size of less than 1cm and a thickness of 2cm. There are no overlaps and no gaps. There is no precipitation before emergence, and the precipitation is used to produce the whole process of rain feeding without topdressing.

Abstract

The invention discloses a film mulched wheat planting method achieving automatic seedling emergence, weeding and evaporation reducing purposes. The planting method is suitable for automatic seedling emergency and water-saving cultivation of film mulched wheat in arid and semi-arid zones. The planting method is characterized in that by the use of the stronger puncturing functions of embryos of the wheat under the dark condition, and the characteristics of small weed seeds and poor embryo puncturing capability, the ground is leveled after planting, and then a degradable micromembrane with the thickness being smaller than 0.004 mm or a degradable black mulching film with the thickness which is less than or equal to 0.006 mm is subjected to full-field covering, and a key technical method that the film is covered with soil with the thickness of 1 to 2 cm, the total of the sowing depth and the soil covering thickness is less than or equal to 5 cm is adopted, so that the purposes that the wheat punctures the film automatically to realize seedling emergence, the weeds cannot puncture the film and is killed due to yellowing, and the full-field plastic film mulching inhabits soil moisture from evaporation efficiently to achieve water conservation and weed control are achieved. The planting method is simple to operate and convenient to implement, can ensure the unit area yield of the wheat, and can improve the moisture utilization efficiency of the wheat and eliminate harm caused by wheat weeds.

Description

technical field [0001] The present invention relates to a new crop planting method, which is especially applied to the cultivation of winter wheat and spring wheat to reduce evaporation, save water and prevent and eliminate weeds in the field. A new experimental method. Background technique [0002] (1) The problem of water saving in wheat production needs to be solved urgently [0003] The main wheat production areas are located in the northern arid area, with a long growing period and a stable dry season. When the temperature rises in spring, the soil water evaporates vigorously. At the same time, the country’s rigid demand for wheat production and the increasingly severe arid climate in recent years and groundwater resources are becoming increasingly depleted. The contradiction between water supply and demand in wheat production is extremely acute. Plastic film mulching is the main technical means of saving water in crop production at present, but the traditional mulchi...
