Abstract
The invention provides a rape-corn-sweet potato interplanting method. The key points of the method is as follows: fine breeds are selected; after the preceding crops are harvested in the last ten-day period of October and the first ten-day period of November, the land is ploughed in time; a bedding with the width of 2m is prepared along the slope; a rape planting belt and a corn reserved belt are kept 1m width for each; the rape and corn will be respectively cultivated for 2 rows; holes are dug according to that the wide line spacing is 1.5 m, the narrow line spacing is 0.5 m, and the row spacing is 0.3 to 0.4 m before transplanting; a single plant is grown in a single hole; the planting density of the rape is 1600-2000 plants per Mu; after the rape is harvested, the sweet potato is grown in the rape belt for 2 rows; after the sweet potato is harvested, an annual interplanting production of the rape-corn-sweet potato in a dry land is finished. By virtue of the method, the benefits are obvious; the manpower resource for harvesting the crops is adjusted; cultivation and soil improving can be combined; seasonal land uncultivation after the wheat is reduced in spring is lightened; compared with the wheat-corn-sweet potato interplanting mode, the income of the rape-corn-sweet potato can be increased by 2343.75 Yuan/hm<2>; and compared with the winter slack-corn mode, the production value is increased to 5468.40 Yuan, and increased by 2250 Yuan.
Description
Technical field
The present invention relates to the cover operation mode of a kind of nonirrigated farmland how ripe cover operation mode, especially rape-corn-three ripe minutes belt wheel works in sweet potato nonirrigated farmland.
Background technology
Chongqing is one of type area of humid region, China south dry farming; Nonirrigated farmland multiple cropping development is very extensive; The vast farmers masses have gains in depth of comprehension to the nonirrigated farmland multiple cropping very much in long term production; Through, mix, mode such as cover, on traditional wheat/jade/sweet potato interplanting basis, innovated the many cooked mode in multiple nonirrigated farmland.The data that provides according to Chongqing City's statistical yearbook shows, since the Chongqing City is directly under the jurisdiction of from 1998 to 2007, whole city's wheat planting area reduced 534.9 ten thousand mu, has nearly 4,000,000 mu nonirrigated farmland interplanting wheat to withdraw from.Adjusting and reducing in a large number of wheat; Caused the constructive variations of traditional wheat-jade-sweet potato cover operation mode; If capture nonirrigated farmland interplanting wheat 1/4 of the area that decreases with the Wild cabbage type double-low rapeseed; Can increase 1,000,000 mu of rapeseed cultivation areas newly, 80,000 tons of the rape seed that raises productivity and improves the quality, this means a great to the effective supply that promotes whole city's increasing peasant income and vegetable oil.
It is with the obvious advantage to replace traditional wheat-jade-sweet potato oil with rape.Rape is done sth. in advance 5-10 days results than wheat, and the human resources that can regulate " three rob " time effectively reduce labor cost, improve the intensive cultivation level, help relevant high crop yields such as corn; Nonirrigated farmland interplanting rape also helps and beautifies the rural area, promotes the development of sight-seeing agriculture, promotes increasing peasant income; Rape is compared with wheat, and soil fertility is had good fertilization effect, can reach the purpose that combines with supporting; Rape substitutes the position of wheat in the how ripe interplanting in nonirrigated farmland as dominant crop, can alleviate whole city's wheat greatly and adjust and reduce back seasonality in late autumn the exposing of nonirrigated farmland of letting a piece of farmland go to waste, and reservoir area of Three Gorges water and soil conservation is had good action; Oil-jade-sweet potato interplanting increases income 2343.75 yuan/hm than wheat-jade-sweet potato cover operation mode
2, than winter slack-the corn pattern increases by 5468.40 yuan of the output values, increases income at 2250 yuan, increases income comparatively remarkable.
Oil/jade/sweet potato nonirrigated farmland cover operation mode is a kind of novel cultivated molding formula under the background that Chongqing City's dryland farming production is nervous in China's vegetable oil material supply and demand, country makes greater efforts to promote oil crop production; It is guaranteeing under the unmoved situation of grain-production such as corn, sweet potato; Increased income one season the branded oil vegetable seed, comprehensive benefit is high, to promoting whole city's vegetable oil material supply; Promoting that increasing peasant income have positive role, is that the molding formula is ploughed in a boundless nonirrigated farmland of application prospect.
Summary of the invention
The present invention is the method for a kind of rape-corn-sweet potato interplanting.Being intended to provides a kind of remarkable in economical benefits to the adjustment of current crop mix, and helps remedying the wheat area and adjust and reduce the back and seasonal novel multiple cropping cover operation mode of letting a piece of farmland go to waste occurs, and the technical measures of multiple cropping cover operation mode of the present invention are following:
A. select breeding for use.
B. specification requirement: late October, early November previous crops such as sweet potato receive the back and in time plough wholely, along opening the railway carriage or compartment in the slope, the wide 2m in railway carriage or compartment, rapeseed cultivation band, corn reserve and are with each loose 1m, rape, various 2 row of corn.
C. transplant density: press wide line-spacing 1.5m, narrow row before transplanting apart from 0.5m, spacing in the rows 0.3～0.4m beats nest, and every nest is planted individual plant, 1600～2000 strains of rape mu density in planting.
D. rape results back plants sweet potato 2 row at the rape band, promptly accomplishes a nonirrigated farmland oil-jade-sweet potato interplanting working year after the sweet potato results, and rape next year, corn are transplanted respectively on corn belt in previous year, the rape band, realizes that the nonirrigated farmland divides belt wheel to do.
Embodiment
A. select breeding for use: select compact, the high Wild cabbage type resistant to lodging of the plant type authorized ripe two low high yield rape breedings and hybrid maize breeding early for use, every mu of land for growing field crops is with rape kind 0.02-0.03kg, corn kind 1.5-2.0kg.
B. cultivate strong sprout: ground, seedbed is chosen in (1).(2) broadcast the back with the clear liquid dung railway carriage or compartment face of drenching, again with ash or the shallow lid of fine earth railway carriage or compartment face.(3) broadcast back chance autumn drought and want timely keeping crop seedling from drought.(4) in time prevent and treat cabbage caterpillar, aphid.
C. middle railway carriage or compartment band is planted: (1) late October, early November previous crops such as sweet potato receive the back and in time plough wholely, along opening the railway carriage or compartment in the slope, the wide 2m in railway carriage or compartment, rapeseed cultivation band, corn reserve and are with each loose 1m, rape, various 2 row of corn.(2) transplant the preceding wide line-spacing 1.5m of pressing, narrow row apart from 0.5m, spacing in the rows 0.3～0.4m beats nest, and every nest is planted individual plant, 1600～2000 strains of rape mu density in planting.
D. corn is selected the hybridization breeding for use, on March, the middle ten days fertile group grow seedlings, cultivate strong sprout, April on, transplant the middle ten days, the branch of noting during transplanting being loose in the rape shop holds together to the rape band is fluffy, the corn that helps revealing reservation is capable, the minimizing rape covers the moon of corn.
E. rape results back plants sweet potato 2 row at the rape band, promptly accomplishes a nonirrigated farmland oil/jade/sweet potato interplanting working year after the sweet potato results, and rape next year, corn are transplanted respectively on corn belt in previous year, the rape band, realizes that the nonirrigated farmland divides belt wheel to do.
