Problems solved by technology

However, in semi-arid areas, north winds are frequent and strong in winter and early spring, and the smooth surface of the mulch film cannot effectively bind the soil, which may easily cause the covering soil on the mulch to be lost, thereby affecting the effect of heat preservation and moisture conservation.
In addition, soil water storage, water absorption and heat absorption capacity are limited, and winter wheat cannot quickly enter the growth period after spring in the cold winter with long dry duration and low temperature, thus affecting the growth and development of wheat

Embodiment 1

[0023] A method for hole-sowing wheat in a semi-arid area, comprising the steps of:

[0024] ①Site selection: Choose plots with flat terrain, deep soil, good soil moisture, and middle-to-high fertility for planting. After the previous crops are harvested, stubble shall be removed in time and deep plowing shall be carried out with 50% phoxim EC 250-300ml mixed with water 30-40g. Soil treatment: 1-2 days after drying the field, finely harrow it to make it deep, fine, flat, and clean, and meet the standards of no soil clods, no stubble, no weeds, empty top and bottom solid, flat field surface, and good moisture content. In order to facilitate film sowing;

[0025] ②Fertilization: 3500-4000kg of heaped farmyard manure per mu, 10-12kg of pure N, P 2 o 5 8-10kg, kg 2 0.8kg is made base manure, and adopts soil bactericide to carry out disinfection;

[0026] ③Seed selection: Select drought-resistant, disease-resistant, high-quality and high-yield varieties, select seeds before so...

Embodiment 2

[0035] As a contrast, the soil moisture and fertilizer of the selected plots for planting are the same as the examples, and each influencing factor is comparable.

[0036] A method for hole-sowing wheat in a semi-arid area, comprising the steps of:

[0037] ①Site selection: Select plots with flat terrain, deep soil, good soil moisture, and medium-to-high fertility for planting. After the previous crops are harvested, stubble shall be removed in time and deep plowing shall be carried out with 50% phoxim EC 250-300ml mixed with water 30-40g. Soil treatment: After drying the field for 1-2 days, finely harrow it to make it deep, fine, flat and clean, and meet the standards of no soil clods, no root stubble, no weeds, empty top and bottom solid, flat field surface, and good moisture content. In order to facilitate film sowing;

[0038] ②Fertilization: 3500-4000kg of heaped farmyard manure per mu, 10-12kg of pure N, P 2 o 5 8-10kg, kg 2 0.8kg is made base manure, and adopts soi...

Embodiment 1 and 2

[0047] Embodiment 1 and 2 test planting winter wheat:

[0048] In the middle and late September of 2016, winter wheat varieties were planted in the semi-arid areas of central and eastern Gansu at the same time. After the same rainwater and weeding management, the length of wheat ears in the two fields was randomly measured and counted in early May 2017. The results It shows that the ears of wheat in the field of Example 1 increase by 0.15-0.22 cm compared with the same period in Example 2. After harvesting in mid-June, the comparison grains found that the grains of Example 1 are fuller, and the yield per mu increases by 12.8% year-on-year, which illustrates the method of the present invention. It has achieved good benefits and can be popularized and applied.

Abstract

The invention discloses a wheat hole sowing method of complete film earthing in a semi-arid area. The method comprises the steps of (1) land selection, (2) fertilization, (3) seed selection, (4) filmlaying and earthing, (5) sowing, (6) seedling stage management, (7) middle and late stage management, (8) pest and disease prevention and control, (9) timely harvesting and (10) film-maintaining and tillage-free successive planting, and is characterized in that in step 4, when film is laid and is covered by soil, after the film is covered by the soil with the thickness of 0.3-0.5cm, the film is also covered by a mixed material with the thickness of 0.5-0.4cm and then is covered by the soil again with the thickness of 0.2-0.1 cm; the mixed material is prepared from, by weight, 50-60 parts of field soil, 100-120 parts of wheat husk, 10-15 parts of humus, 8-12 parts of peat mould, 5-10 parts of coal ash and 5-10 parts of starch residue through mixing. The method reduces field pests and diseases, and can significantly improve the quality and yield of wheat, and test results show that the yield through the method is 12.8% higher than that of an existing complete film earthing wheat hole sowing method.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for hole-sowing wheat in a semi-arid area covered with soil. Background technique [0002] Wheat is the main food crop in the semi-arid region of central and eastern Gansu. Drought, water shortage and low temperature in spring are the main reasons for the low crop yield in this region. Especially in recent years, droughts have occurred frequently, widely distributed, and lasted for a long time, seriously restricting the high and stable yield of wheat. Film-mulching cultivation can significantly increase soil temperature, shallow soil moisture content and utilization rate, can effectively reduce the damage to crops caused by drought and low temperature in spring, promote normal growth and development of crops, and increase yield. However, film mulching will also have a negative effect on wheat growth under certain conditions. After film mulching...
