Description
Technical field
The present invention relates to the implantation methods of crops, and in particular to a kind of implantation methods of drip irrigation interplanting corn soybean, category
In agricultural plantation technology field.
Background technology
Corn is grain, feed, processing, the polynary purposes crop of the energy, has act in China's agricultural production and national economy
The effect of sufficient weight.Arid is probably the most important factor for limiting crop yield in the world, in northern China due to prolonging
The drought stress that irrigation or irregular precipitation are caused late seriously governs high crop yield stable yields.
North Xinjiang in 1996 introduces drip irrigation technique, and Xinjiang is creative to be combined engineering teaching and Agricultural Water Saving, shape
Into the drip irrigation under film with New function, and corresponding product is developed, with water saving, section is fertile, save land, save machine power, section
Manually, heat, suppress weeds in field growth, keep and improve soil granular structure, raise labour productivity and can be in good time, suitable
Amount meets requirement of the crop each breeding time to water and nutrient, improves water, fertilizer, the air and heat growing environment of plant growth etc. comprehensively all
Many advantages.
The characteristics of drip irrigation technique is due to its high-efficiency water-saving and promoted the use of a large area in Xinjiang, end the end of the year 2015, drip irrigation
Technology has promoted 2,790,000 hectares in Xinjiang, and 80% area is there are about at present using drip irrigation Fertigation technology, is achieved well
Economy and ecological benefits.
Corn drip irrigation technology is that Condition in North Xinjiang is directed to actual production demand, on the basis of drip irrigation for cotton technology, overlay film kind
A kind of new irrigation technique that planting technology is combined with drip irrigation technique, is the revolution to cereal crops irrigation method.Liquid manure
It is the material guarantee of agricultural sustainable development, is the basis of increases in grain production, while water and fertilizer is arid, semiarid zone influence agricultural
The key constraints of production, therefore improve the important management objectives that water and fertile utilization rate are agricultural productions.But drip irrigation bar
With there is larger difference in the liquid manure supplying mode under part, irrigate has larger difference with fertilizer practice and pattern on other Irrigations
It is different.
Plant is tall and big, and breathing and photosynthesis are strong, are typical C4 crops, soybean plant strain is relatively short and small, compares happiness
The moon, the two has different adaptability to strong light.Two kinds of crop interplantings play the role of mutually to utilize, learn from other's strong points to offset one's weaknesses, improve yield.
The content of the invention
It is an object of the invention to provide a kind of respective per unit area yield yield height, the kind of the obvious drip irrigation interplanting corn soybean of benefit
Plant method.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
A kind of implantation methods of drip irrigation interplanting corn soybean, it is characterised in that comprise the following steps：
Step1：Site preparation
The preceding deep placement base fertilizer of sowing simultaneously flattens ground；
Step2：Seeding corn and pipe laying
Corn is planted using width between-line spacing, wide row width 85cm~100cm, narrow row width 60cm~75cm, in narrow row
Two drip irrigation zones, drip irrigation zone and corn seeding row distance 8cm~12cm are laid, is sowed using bunch planting pattern under film, hill spacing 34cm,
Per 3, cave, sowing, pipe laying, plastic film mulch and earthing are completed using seeder；
Step3：Sow soybean and pipe laying
Soybean is interplanted in drip irrigation corn wide row, and a drip irrigation zone, drip irrigation zone both sides are laid in the middle of drip irrigation corn wide row
1 row soybean of each sowing, soybean planting line-spacing 15cm~20cm, hill spacing 30cm~40cm, per 2~3, cave；
Step4：Seedling stage field management
Corn is supplied water with soybean using independent water band, after planting, is connected hollow billet on the stringing of field, is oozed Miao Shui, according to
Soil moisture content is per 667m2Corn drips 12m3~18m3, per 667m2Soybean is dripped 6m3~10m3, apply that respectively to ooze seedling special with water droplet
Fertile 1.5kg~3kg；
Step5：Growth phase field management
Soybean row soil moisture content is kept between the 65%~80% of maximum field capacity by drip irrigation, in drip irrigation mistake
Topdressed in journey with appropriate amount of water；
When corn shoot upper blade is rolled, start the first water of corn row and irrigate, corn row is kept by drip irrigation afterwards
Soil moisture content is topdressed between the 70%~85% of maximum field capacity during drip irrigation with appropriate amount of water；
Step6：Harvest
When soybean and corn reach the respective harvest best opportunity, harvested, afterwards corn stalk returning to the field, Second Year
Without the rotation of crops, directly wrong row plantation in situ.
Foregoing implantation methods, it is characterised in that in Step2, drip irrigation corn wide row width 90cm, narrow row width
70cm, drip irrigation zone and corn seeding row distance 10cm.
Foregoing implantation methods, it is characterised in that in Step3, soybean planting line-spacing 18cm.
Foregoing implantation methods, it is characterised in that in Step4, water dropper on drip irrigation belt flow is controlled according to the soil texture, husky
Loam corn drip irrigation band dripping end flow control 2.4L/H~2.8L/H, soybean water dropper on drip irrigation belt flow control 2.6L/H~
3.0L/H, loam corn drip irrigation band dripping end flow controls to exist in 2.2L/H~2.6L/H, the control of soybean water dropper on drip irrigation belt flow
2.4L/H~2.6L/H, clay corn drip irrigation band dripping end flow is controlled in 1.8L/H~2.2L/H, soybean water dropper on drip irrigation belt flow
Control is in 2.0L/H~2.4L/H.
Foregoing implantation methods, it is characterised in that in Step5, are irrigated for the water of corn row first, according to soil moisture content
Per 667m2Drip 25m3~30m3, Fertigation.
The present invention is advantageous in that：
(1) corn is C4 crops, and plant is tall and big, like strong light, and soybean plant strain is relatively short and small, it is cloudy to compare happiness, and the two is to strong
Light has different adaptability, after corn and soybean interplanting, and corn is that soybean blocks strong light, there is provided cool place, soybean
In the presence of demand of the corn to strong light can't be influenceed, so corn and soybean each obtain higher per unit area yield yield, benefit
Substantially；
(2) corn is supplied water with soybean using independent water band, it is ensured that the two respective liquid manure supply, has been provided for volume increase
Effect is ensured；
(3) corn is planted using width between-line spacing, by corn stalk returning to the field after harvesting, the directly in situ wrong row kind of Second Year
Plant, has not only conserved arable land, and has realized same arable land inside and led stubble well.
