Description
Technical field
The present invention relates to the non-irrigated seedling field of early rice, more specifically relate to a kind of method of seedling culture under dry condition, be particularly useful for the seedling culture under dry condition of southern china (the particularly middle and lower reach of Yangtze River one band) double rice cropping system, also be applicable to the non-irrigated seedling of the single cropping rice and semilate rice and ratoon rice.
Background technology
Rice cropping divides live and two kinds of forms are transplanted in seedling.Direct-seeding Rice with a long history formed two kinds of supporting technologies of water direct seeding and direct-sowing dry, and the countries and regions many less the people have obtained extensive use, have obtained the effect that significantly saves labor.But have a large population and a few land, unit yield and the high countries and regions of cropping index, at present still based on the seedling transplanting.
Japan begins the paddy drought seedling technical research from nineteen thirty-five, and by research, the problem that having solved Direct-seeding Rice can not early sowing, rotten and dead seedlings easily takes place watery ricenursery has received that early sowing is early inserted, premature ripening and alleviate the effect of later stage low temperature harm.Nineteen sixty-five, the non-irrigated seedling-cultivation technique of Japan is promoted and is peaked, and non-irrigated seedling is used area and accounted for more than 95% of rice cropping area.
China from the beginning of the fifties to the eighties, large-area applications be that watery ricenursery is transplanted.Watery ricenursery causes mashed kind of seedling rot and dead seedling because the seedbed is in the water layer for a long time, and the soil aeration performance is poor, after planting bud paddy takes root and holds up pin slow, and root growth is bad, thereby causes affecting adversely farming, influence cultivation season, makes whole year production passive.In order to alleviate the rotten and dead seedlings of two season early rice, the intermediary and later stages sixties begin application " water-raised seedling cultivation ", and this is to preventing the rotten and dead seedlings of two season early rice, early sowing, early insert, relax season contradiction and the raising per unit area yield played important function.But remaining, water-raised seedling meet in strong seedling and concerning of strong root that the low temperature overcast and rainy day time, rotten and dead seedlings still took place and the not solution of problem that the stiff seedling in back is not sent out is early inserted in early sowing in problem, early spring.The drought seedling is to grow seedlings on the seedbed, nonirrigated farmland, regulates and control the water demand of rice shoot with water, to reach the strong seedling purpose of the strong root of strong seedling, strong stress resistance.At the beginning of the seventies, a band is economized in Hunan, Zhejiang etc., takes the lead in having attempted " non-irrigated seedling seedling balled transplanting technology ", but unresolved because of key technology, operating technology is lack of standardization, and the seedling quality of breeding is relatively poor, the output effect is not remarkable, how long has not just disappeared in a flash so do not use on producing.The beginning of the eighties and the beginning of the nineties, " cold ground drought is educated seedling thin planting technology " and " the rice shoot with rsgun and wide planting high yield technique " of Japan successively introduced in Zhejiang and Hunan.Develop into " plastic floppy disk seedling throw plant technology " in recent years again, overcome basically in the past that the dry bed soil layer is thin, water retention capacity difference and soil fertility is low and cause the thin and weak drawback of seedling growth, prevented the rotten and dead seedlings problem basically.But, non-irrigated seedling that grows up at present (educating hereinafter to be referred as general drought) and plastic floppy disk seedling throw to plant also its shortcoming and defect, for example, general drought is educated and is just existed the difficulty of pulling up seedlings, and the plastic floppy disk seedling just exists problems such as cost height, troublesome poeration, labour intensity are bigger; During sowing,, still exist mashed kind, seedling rot, dead seedling problem as the low temperature overcast and rainy day sky time of a specified duration partially.

| Drought is educated the general drought of new method and is educated water-raised seedling | 95.40 93.50 80.16 | 91.18 88.16 56.15 | 4.32 4.56 5.45 | 15.25 16.39 18.76 | 4.43 4.49 5.00 | 2.90 2.74 2.67 | 79.55 72.36 13.24 | 14.8 12.6 6.7 | 3.6 3.4 2.2 |
Sowing on March 20th, 1996, March 24 emerged, and March 26, daily mean temperature was the 7.2-12.2 degree to low temperature overcast and rainy day on continuous 9 days of April 3, belonged to the seedling culture under dry condition temperature time on the low side.Transplant preceding 2 days examination cold resistances of rice shoot and quality in table 4: the emergence rate that drought is educated new method rice shoot is 95.4%, educate and water-raised seedling difference high 1.9% and 15.2% than general drought, percentage establishment of seedling, it is 91.8% that drought is educated new method, educate and water-raised seedling difference high 3.02% and 35.03% than general drought, show drought educate new method rice shoot emerge the back under the natural stress conditions of continuous 9 days low temperature overcast and rainy days, rice shoot has stronger cold-resistant advantage.From seedling quality, leaf age and height of seedling are drought and educate new method and be lower than general drought and educate and water-raised seedling.Though hundred strain dry weights are droughts educates new method and is lower than general drought and educates and water-raised seedling, but from the sturdy degree of rice shoot, then be that drought is educated new method and is higher than general drought and educates and water-raised seedling, adding stem foot wide also is that drought is educated new method and is higher than general drought and educates and water-raised seedling, this explanation drought is educated new method seedling growth slowly and steadily and surely, the quality height.The white root that drought is educated new method rice shoot is 14.8 of every seedlings, is higher than general drought and educates and water-raised seedling.The band tiller rate that drought is educated new method rice shoot is 79.55%, is higher than general drought and educates and water-raised seedling.This has illustrated that drought educates that new method rice shoot has stronger root system vigor and with the short tiller advantage of root.
6, seedbed scientific management: water management adheres to that drought educates drought pipe, and the rice seedling bed is held the railway carriage or compartment ditch successfully and enclosed ditch, accomplishes that the ditch ditch communicates, and guarantees that rain stops not water breakthrough.When the fertile mud layer in fine no rain of a specified duration seedbed is now white, adopt furrow irrigation (70%-80% that the water irrigation ditch is dark) moistening seedbed.Temperature treatment fine day, seedbed temperature in the shed reach 30 when spending, and take off film aeration-cooling (temperature drops to about 25 degree and is advisable) at the two ends, seedbed, in case high temperature (35-38 degree) " burning seedling " and cause rice shoot excessive growth.Hardening rice shoot three leaves are taken off the film hardening after wholeheartedly, can transplant in hardening 5-7 days.
