Problems solved by technology

The purpose of moisture preservation is achieved, but the straw decomposition and crop emergence are carried out at the same time, competing for nutrients, and the straw decomposition is not complete, which seriously affects the emergence of the next crop; at the same time, it brings inconvenience to irrigation and causes a waste of water resources
[0006] 3. It is labor-intensive, time-consuming, and land-consuming to remove straw from the field, which has rarely been adopted by farmers.
[0007] 4. Straw burning causes resource waste, environmental pollution, ecological damage, and affects traffic and people's lives at the same time, which has become a major public hazard

Embodiment 1

[0030] A cultivation method for furrow and ridge cultivation, comprising the steps of:

[0031](1) In spring, after harvesting mature fruits of winter and spring crops, set wide and narrow rows on the uniform ridge cultivation field, with a width of 50-90 cm and a narrow row of 30-40 cm, furrows are made on the wide rows with a depth of 35 cm, and the winter and spring crop straw Bury or pulverize and fill in the ditch, about 2.1 tons of straw can be placed in the ditch. Fertilize once in the ditch before returning to the soil after burying the straw. 2 o 5 In terms of potassium active ingredients in K 2 In terms of O, its active ingredient ratio is: 20:10:15. ) compound fertilizer 45 kg / mu; ditch soil backfill. The amount of irrigation per mu in the ditch is 60m 3 ;Due to the high rainfall during this period, most of the runoff and infiltration rainfall will flow into the furrows, which will accelerate the decomposition of the straw in the furrows, release mineral nutrie...

Embodiment 2

[0036] Corn / Wheat Rotation

[0037] 1) At the beginning of June in spring, after the harvest of mature wheat fruits, set up wide and narrow rows on the ridge cultivation field, with the width of 90cm and the narrowest of 40cm, plow furrows on the wide rows with a depth of 35cm, and bury or crush wheat straw into the furrows , Mu Shi in the ditch (N-P 2 o 5 -K 2 O=20-10-15) 45 kg of compound fertilizer; backfill the ditch soil; irrigate 60m per mu in the ditch 3 .

[0038] 2) Sow 2 rows of corn on the narrow row close to the furrow, with a spacing of 10-15cm. During the corn jointing stage and the grouting stage, water needs to be watered twice, all of which are poured into the furrows, and the amount of water for each time is 60m 3 / mu. Routine weeding and spraying. The root system of corn is close to the furrow, and the extension of the root system can absorb the water in the furrow and the nutrients released by the straw decomposition. The variety of corn is Zhengda...

[0045] Corn / February Crop Rotation

[0046] Corn is used as the main crop in summer and autumn, and Er Yue Lan is used as a kind of winter green manure. It is cultivated in winter and spring, and the seeds are harvested in June of the following year. Set wide and narrow rows, the ridge surface (narrow row) is 40cm wide, the furrow (wide row) is 60cm wide, and the furrow depth is 35cm, bury winter green manure Eryuelan straw, apply per mu in the ditch (compound fertilizer refers to: nitrogen, phosphorus, potassium compound Fertilizer, its pure nitrogen is calculated as N, and the active ingredient of phosphorus is calculated as P 2 o 5 In terms of potassium active ingredients in K 2 In terms of O, its active ingredient ratio is: 20:10:15. ) 45 kg of compound fertilizer; backfill the ditch soil; irrigate 60m per mu in the ditch 3 . At the beginning of May, the corn seeder planted 2 rows of corn on the ridge, with a plant spacing of 10-15cm; used herbicides to kill weeds in ...

Abstract

The invention discloses a furrow straw ridge cultivation method. According to the method, ridge wide and narrow row annual alternate planting is carried out in summer and autumn and in winter and spring, and straws in rows are alternately furrowed and buried in the planting rows, wherein the wide and narrow rows include narrow rows with the row spacing of 30-40 cm and wide rows with the row spacing of 50-90 cm. Most rainwater flows into furrows through runoff and infiltration, and irrigation and fertilization are carried out in the furrows. By the adoption of the furrow straw ridge cultivation method, the problems that the seedling emergence rate is low and diseases and insect damage are caused easily as straws cover the earth surface or the straws are not completely decomposed are solved, the straws are completely decomposed and efficiently returned to the field all year round, and soil fertility is improved. Meanwhile, due to the fact that irrigation and fertilization are carried out in the furrows, water storage and soil moisture conservation are facilitated, and the water and fertilizer utilization efficiency is improved. The furrow straw ridge cultivation method is wide in application range, double-crop rotation is carried out every year, and the planting method is scientific.

Description

technical field [0001] The invention relates to a method for planting two crops a year, in particular to a method for cultivating summer and autumn / winter and spring crops in furrows and ridges. Background technique [0002] Crop straw is a by-product of agricultural production and an important fertilizer resource because of its large quantity and wide distribution. During the growth of crops, a large number of nutrients are taken from the soil. Straw returning can effectively replenish organic matter. The dynamic balance of soil organic matter accumulation and mineralization can be maintained by returning straw to the field: ①Enhance soil fertility and water retention. ②Promote the formation of soil aggregate structure and improve physical properties. ③Promote the physiological activities of plants and microorganisms, and have the functions of preserving moisture and inhibiting the growth of weeds. (That is, the organic acid produced when the straw decomposes can neutra...
