What are the technological innovations in soybean 45cm double-strip dense cultivation? What effect has it achieved?

Soybean 45cm double-strip dense planting cultivation technical innovation points

1, planting method to achieve innovation, to create a uniform plant of high light efficiency group structure

The traditional monopoly crop 65cm-70cm spacing narrowed to 45cm, the average spacing between rows of 32.5cm-35 cm narrowed to 22.5 cm, the spacing between the 6.8cm-8cm increased to 10cm-12cm, double row spacing 10cm-12cm, plant spacing is also 10cm-12cm. The average row spacing of 32.5cm-35 cm was reduced to 22.5 cm, and the plant spacing from 6.8cm to 10cm-12cm, and the spacing of small rows between double rows was 10cm-12cm and the spacing of plants was also 10cm-12cm, so as to build up the group structure of "equal spacing and even plants", and to ensure that the group advantage on the basis of the nutritional space of soybean group tends to be more reasonable. The scientific and technological research: this model, technical characteristics of the domestic has not been reported.

2, variety screening and application to achieve innovation, the realization of high density, high-yield cultivation technology new route

Change the conventional hi sparse planting in the high scales of the more bushy-type varieties for the semi-dwarf density resistant varieties of anti-pouring, at present *** screened out the Hopfon 42, red Feng 11, Kenfon 16, and so on a large number of the current varieties suitable for the technology. Conventional ridge crop hectares of 20-30 million seedlings to 35-45 million plants, an effective solution to the current soybean production per unit area of the number of seedlings is not enough drawbacks to break through the planting of existing varieties in the current production conditions, planting density is difficult to increase the forbidden zone.

3, the farming system to achieve innovation, integration of new drought-resistant soybean less plowing energy-saving cultivation technology system

Changing the traditional spring or the original ridge planting mechanized deep pine rotary or harrowing stubble for mechanized volts in the autumn to not have a ridge, reducing the soil scattered full-fledged area; change the traditional ridge seeding for the flat sowing ridge tube, with the sowing of the ridge with the sowing of the heavy compression after sowing. Drought protection picking, effectively cracked the long-standing problems of soybean production in our province in the spring a drought seeding to ensure that all the technical difficulties; change the traditional field management 3-4 times plowing for 2 times, to protect the soil structure; reduce the operation links, generally mu can reduce the mechanized cultivation fee 8.6-14.0 yuan.

4, technology integration and assembly to achieve innovation, leading the direction of development of new technologies for soybean production

Establishment of agricultural fertilizers and chemical fertilizers, N, P, K and the combination of microelements, to promote the combination of control, layered side of the depth of fertilizer fertilization of the best fertilizer combinations and fertilizer technology; to further improve the supporting integrated pest and weed prevention and control of the technical system; to achieve the Agricultural machinery and agronomy supporting. The application of existing rural 18 or 24 horsepower and other commonly used tractors can be realized traction operations, 2BTG-( 2 )3-type universal seeder to achieve precision seeding, conventional plow according to the requirements of the 45 cm row spacing can be completed deep pine trips ridging operations.
