Abstract
The said technique is that maize of two or more varieties is mixed-planted or intercropped. The said technique can fully utilize the resource of soil, light, air, heat and water and increase the resistance of maize to diseases and insect pests as well as drought, waterlogging, wind, cold and other natural calamities. Comparing with available technique it can result in an increase of maize production by 10%.
Description
The invention belongs to the Maize Production technology.
Domestic and international existing corn planting technology generally adopts the single corn variety sowing of genotype unanimity.This Maize Production technology is emphasized the purity and the field regularity of colony.There is following shortcoming in it: (1) can not more make full use of resources supplIes such as land fertility and light, gas, heat, water.(2) certain fragility is arranged aspect disease, worm, drought, waterlogging, wind, the natural calamity such as cold resisting.(3) can not give full play to individual yield potential.
The objective of the invention is to, under the prerequisite that does not increase any production cost, increase corn yield, improve resistance and yield stability.
Main contents of the present invention are as follows:
1, kind equipping rules: select morphological differences complementation between unanimity breeding time, kind, resistance complementation, contemporary hybrid vigour is strong, yield potential the is big different corn single cross hybrid of two or more genotype, their seed is evenly mixed between back sowing or kind plant.
2, determining of kind number: according to the ecological condition of different regions and local main breed number what, natural calamity situation and soil, fertilizer, aqueous condition, cooperation advantage size etc. is determined suitable varieties of plant number between kind.
The determining of row ratio when 3, planting between seed mixed proportion during mixed planting or different kind: according to kind number and breediness, the capable ratio of planting between seed rate when determining mixed planting or different kind, and then according to the grain weight of each kind, the seed weight ratio that germination rate is identified for sowing.
Technique effect of the present invention is as follows:
Compare with the contrast of plantation single variety, the adaptability and the resistance of natural conditions is obviously improved, yield stability strengthens, and per unit area yield can increase more than 10%.Need not increase production cost, method is simple, easy operating.
The present invention can realize by following examples:
Embodiment 1
(1), in areas of Shenyang, according to morphological differences complementation between breeding time unanimity, kind, resistance complementation, contemporary hybrid vigour is strong, yield potential is big kind configuration requirement, select 5003 * E28,7945 * 5003 and B11 * 360 3 a corn single cross hybrid for use.
(2),, seed germination rate heavy and geometric ratio sowing requirement according to each kind grain, determine that the seed sowing weight ratio of 5003 * E28,7945 * 5003, B11 * 360 is 1: 1.2: 1.31, sowing after their are evenly mixed.
(3), cultivation management after planting and results: by existing routine techniques operation.
Embodiment 2
(1), in areas of Shenyang, according to morphological differences complementation between breeding time unanimity, kind, resistance complementation, contemporary hybrid vigour is strong, yield potential is big kind configuration requirement, select 5003 * E28, B11 * 360 two a corn single cross hybrid for use.
(2),, seed germination rate heavy and not geometric ratio requirement according to two kind grains, determine that 5003 * E28 and B11 * 360 field seeds sowing weight ratios are 1: 1.7, after fully mixing, sow.
(3), cultivation management after planting and results: by existing routine techniques operation.
Embodiment 3
(1), in the area, Tieling, according to morphological differences complementation between breeding time unanimity, kind, resistance complementation, contemporary hybrid vigour is strong, yield potential is big kind configuration requirement, select Shen Dan for use No. 3, No. 4 two corn single cross hybrid of Shen Dan.
(2), according to selected kind number and breediness, the capable ratio of field planting that No. 4, determine Shen Dan No. 3, Shen Dan is 2: 2, sowing according to a conventional method then.
(3), at tasseling stage, No. 4, Shen Dan is carried out artificial emasculation, divide secondary to finish.During castration, accomplish not damaged blade.Other measure such as field management is identical with routine techniques.
(4), ripe back mixing results get final product.
The effect of increasing production of miscegenation
The effect of increasing production of planting between different kind
Claims (1)
1, a kind of planting technology of corn yield increasing is characterized in that selecting morphological differences complementation between unanimity breeding time, kind, resistance complementation, contemporary hybrid vigour is strong, yield potential the is big different corn single cross hybrid of two or more genotype to carry out planting between mixed seeding or different kind.
