Embodiment

[0024] Embodiment (full film-covered planting)

[0025] Field selection: Tartary buckwheat does not have strict requirements on soil and stubble, and it is suitable to choose clay, loam, and sandy soil in terraced fields, rivers, and plateaus. Generally, flat land below 15° is selected; avoid heavy cropping for more than 2 years, the most suitable The previous crops were potatoes, legumes, rapeseed, flax, wheat, etc.;

[0026] Deep plowing and moisture storage: After the previous crops are harvested, loosen them with a subsoiler and plow 30-40cm deep.

[0027] Soil preparation-fertilization: After the soil is thawed in the second year, use a rotary tiller to plow the land at a shallow depth of about 20cm, and generally apply high-quality decomposed farmyard manure at a rate of 22.5-45.0t / hm in combination with land preparation 2 、N 40kg / hm 2 ,P 2 o 5 30kg / hm 2 、K 2 O 20kg / hm 2 . Level the surface, so that there is no stubble on the top and bottom, the ground is flat a...

Embodiment 1

[0052] Example 1 Hole planting with full film covering soil has a significant impact on the yield, water consumption and water use efficiency (WUE) of tartary buckwheat.

[0053] In the 3-year experiment, the yield of full film-covered soil hole-sowing was significantly higher than that of traditional open field (P-2 , an increase of 7.26% compared with the traditional open field; the yield of full-film-covered soil hole-sowing is 2158.22kg·hm -2 , an increase of 95.25% compared with the traditional open field; the yield of full-film-covered soil hole-sowing in wet years is 2712.78kg·hm -2 , an increase of 11.46% compared with the traditional open field; the three-year average yield of full-film-covered soil hole-seeding is 638.41kg·hm more than the traditional open field -2 , an increase of 33.42%.

[0054] In Example 1 and Comparative Example 1, there was no significant difference in the water consumption of tartary buckwheat between treatments in normal water year and shor...

Abstract

The invention discloses a green synergistic planting method for bitter buckwheat in dry land, and relates to the technical field of agricultural planting. The method includes covering the whole bitterbuckwheat planting land with a full biodegradable mulch film; covering the mulch film with soil; performing sowing on the mulch film with soil by simple mechanized hole seeding; performing normal field management, harvesting after the buckwheat is mature, retaining the mulch film after harvesting and timely sowing the next crop. The method adopts a high-efficiency cultivation technique integrating the whole land mulch film + film covering with soil + hole seeding + no-tillage and multi-crop planting, and the whole film covering hole seeding technique can effectively improve soil water content, increase soil accumulated temperature, promote growth and development, improve the utilization efficiency of water resources, achieve high yield and stable yield of the bitter buckwheat in semi-aridarid crop area and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for green and synergistic planting of tartary buckwheat in dry land. Background technique [0002] Buckwheat belongs to Polygonaceae (Polygonaceae), a dicotyledonous plant, divided into two types: sweet buckwheat and tartary buckwheat. It is resistant to barrenness, has a short growth period, and has high nutritional value. people's attention. Buckwheat is the main miscellaneous grain crop on the Loess Plateau in Northwest China. Buckwheat in Gansu Province is mainly distributed in the dry-farming areas of East and Central Gansu, with an annual sown area of ​​60,000 hectares. [0003] However, due to the lack of rainfall in semi-arid areas, uneven distribution of rainfall, frequent seasonal droughts, and lack of attention to planting, the yield of tartary buckwheat is low and unstable. The yield per mu is about 100kg, and the comparative benefit is low. ...
