Description
Technical field
The present invention relates to a kind of advantage utilizing wheat root dish to tie power strong in hybrid rice production of hybrid seeds seedling field improve and improve the method for transplanting colony quality.Together sowed by paddy rice and wheat, use wheat seed young root coring flourishing, dish knot power is strong, later stage is easy to curling not easily broken advantage and carrys out friendly machine rice transplanting seedlings root mutually coil knot in seedling-nursing flexible tray or hard disk, drive seedling block overall solid not fugitive, artificial easy curling easy transport Yi Shangji, after the machine transplanting of rice, can significantly promote rice shoot to turn green growth, short tiller increases fringe, effectively improves hybrid seed yield.The method can reduce seed rice consumption especially hybrid rice maternal breeding male sterile line sowing quantity, and cost-saving synergistic is obvious.
Background technology
In the staple food crop of China, paddy rice with have very important one seat.Due to wet rice cultivation cropping system, its production link is many, and seasonal strong, the amount of labour used is large.Special the especially blue or green strong labour of rural laborer goes down town in a large number and works and does business, and causes the labour's quantity being engaged in Rice Production fewer and feweri in recent years, and especially in the hybrid rice production of hybrid seeds, it is unrealistic that female parent is planted by pure craft in the land for growing field crops of thousands of mu.Therefore the efficient rice planting technology of dart transfer has adapted to this cultivation mode.
Paddy rice is due to the feature of kind self heredity, plate seedling raising to have packing power strong moulding for japonica rice, be easy to manual curling, transport, upper machine and transplanted by machine, and the especially maternal male sterile line of hybrid rice production of hybrid seeds seedling, dish knot power is more weak, curling easily broken mutually on seedling-nursing flexible tray or hard disk for seedlings root, transports fugitive, during upper machine, seedling block such as easily to split at the shortcoming, has a strong impact on quality and the effect of the machine transplanting of rice.In actual transplanting seedling process people often through increasing seeding quantity, increase the measure such as Planting Densities and improve and plant quality, waste time and energy, the male sterile line seed rice consumption in every mu of land for growing field crops even reaches 2.5-3kg, transplanting root system dish knot is still undesirable, in addition highdensity sowing quantity and faster leaf growth speed, very easily cause rice shoot to cover, transplanting colony quality declines on the contrary, be unfavorable for cultivating strong seedling, so affect transplanting plant after land for growing field crops colony quality and later stage hybrid seed yield.
The key difference of transplanting and traditional watery ricenursery or water-raised seedling is that thickness of sowing is high, the length of time rice seedlings grow is short (about 20 days), when planting, rice shoot has just been in three leaves wholeheartedly age at weaning, this stage must plant in time, plant that the too little root system of rice shoot is too short cannot go up machine too early, spending late the i.e. length of time rice seedlings grow longly will affect the early growth and quick tiller of planting rice shoot.Rational transplanting colony quality, should possess root system dish and tie power by force, coring is white, plays seedling fast, easy curling easy transport Yi Shangji, the feature that seedling plate is not easily broken, and after the machine transplanting of rice, rice shoot is turned green and tillered soon.
Through consulting, the method patent of invention of improvement transplanting seedling close with it has: CN1930936A is a kind of method ensureing transplanting strong sprout by controlling the amount of broadcasting.CN102498999A is a kind of method being improved production of hybrid seeds transplanting by cultivation steps such as fertilizer, water managements.CN202476172U is a kind of method changing seedling quality by improving seedling-cultivation plate device.CN102150657A is short tiller effect of turning green in a kind of later stage of improving transplanting by plant growth regulator (moulding root agent etc.).Above-mentioned disclosed patent is only for the method that common machine rice transplanting improves, comprise the measures such as seedling raising device, conditioning agent, culture technique, to some extent solve the transplanting seedling predicament of a certain particular aspects, but higher to the requirement of operating personnel, or early investment cost is larger.The present invention is obviously different from above-mentioned patent in mode and content, fully uses root system of plant influencing each other in soil, especially for hybrid rice production of hybrid seeds field, simple and clear, is easy to grasp, workable.
The present invention mainly develops: in hybrid rice production of hybrid seeds seedling link, by adding a certain proportion of wheat seed in seedling dish seeding process, utilize wheat young root dish to tie the strong advantage of power to assist to increase coiling of transplanting root system, rice shoot root system is helped mutually to coil knot moulding in dish, meet the requirement of transplanting to root system, both can reduce paddy rice sowing quantity, cost-saving, low-density growing environment is easy to again cultivate strong seedling in addition, be convenient to curling, transport and upper machine plant.Due to the growth characteristics of wheat after planting, wheat seeding cannot be taken root growth in paddy field, does not deposit competition that is fertile, water, to Rice Population without any negative effect, plants rear male sterile line colony and turn green soon, be easy to production of hybrid seeds colony early growth and quick tiller.
According to the observation and analyze, the quality improving hybrid rice production of hybrid seeds seedling link transplanting in early stage must be set about from colony quality in seedling stage aspect.In the transplanting premature rice stage, in appropriate seed rice, add the wheat seeds of some according to a certain percentage, simple and easy to do, cost is lower, workable, Be very effective, hybrid rice production of hybrid seeds transplanting colony quality can be improved, turn green rapidly after being beneficial to rice shoot transplanted by machine, tiller.Therefore patent of the present invention has significant cost-saving synergistic effect, possesses novelty, originality and practicality.
