Abstract
The invention discloses a pollination method for hybrid rice breeding seed production by a fan, more specifically to a pollination method suitable for simplified breeding seed production of hybrid rice, i.e. a portable charging fan pollination method. The row spacing and column spacing of the rice field are both 5 cun (a unit of length of about 3.33cm), only male parents or female parents are planted to each column, and the planting proportion of the male parents to the female parents is 1:3. When the male parents and the female parents bloom, the male parents are blown by a fan at one side of the ridge, pollen of the male parents is blown to the place above the female parents and then falls evenly. Pollination is carried out once at an interval of 0.5h-1h by the fan, three times a day. The method can be more timesaving and labor-saving, lowers the labor intensity and cost, improves the utilization rate of the male parent pollen, and successfully promotes rapid development of the hybrid rice breeding seed production technology.
Description
Technical field
What the present invention relates to that a kind of fan carries out crossbreeding rice catches up with powder method, be more particularly the crossbreeding that gently simplifies of a kind of applicable hybrid rice catch up with powder method---powder method caught up with by portable charged fan.
Background technology
Current crossbreeding rice catch up with powder method to mainly contain dragline type to catch up with powder, catch up with powder, vertical row to catch up with powder three kinds of methods to bamboo pole along male parent pedestrian work bamboo pole.Dragline type catches up with the method for powder because labour intensity is little, time and labour saving, cost are low, be applicable to the application of large area crossbreeding, but because the elasticity dynamics of rope is little, elasticity is uneven, cause male parent can not loose powder fully, if catching up with misoperation in powder process, also can significantly reduce paternal pollen availability, affect the output of crossbreeding.Catch up with the method for powder owing to increasing the elastic vibration to male parent along male parent pedestrian work bamboo pole, thus substantially increase the availability of paternal pollen, and the effect of pollination can be significantly improved, but take a lot of work because this mode labour intensity is large, time-consuming, be not easy to apply on large area crossbreeding.The feature that vertical row catches up with powder method to combine dragline type to catch up with powder and catch up with this two kinds of modes of powder to have along male parent pedestrian work bamboo pole to bamboo pole, thus formed a kind of newly catch up with powder method.It refers to catches up with powder people to walk along the vertical direction of father and mother's one's own profession, and with long bamboo pole, (5 m) manually catch up with powder.The method more can accomplish time and labour saving than front 2 kinds of methods, reduce the availability of labour intensity and cost, effectively raising paternal pollen, it is the once improvement that crossbreeding rice catches up with powder method, but still have the space of continuing to improve, because people complete at most every day 2-3 mu catch up with powder workload, labour intensity is also larger, and operating efficiency also has much room for improvement.Human society progressive each time all with the innovation of instrument and utilize closely bound up, 21 century is the epoch that science and technology develops rapidly, much new-type instrument has been born, how to utilize these instruments go to find a kind of more can time and labour saving, reduce labour intensity and cost, effectively improve paternal pollen availability catch up with powder method, to developing rapidly of hybrid rice, there is great social effect.
Summary of the invention
The object of the invention is to solve the technical bottleneck of catching up with at present existing for powder mode, the crossbreeding providing a kind of applicable hybrid rice gently to simplify catch up with powder method---powder method caught up with by portable charged fan.The method can more time and labour saving, reduce labour intensity and cost, raising paternal pollen availability, successfully promoted developing rapidly of crossbreeding rice technology.
In order to solve the problems of the technologies described above, applicant is by finding multiple powder method repetition test of catching up with, and the technical solution adopted in the present invention can well reach goal of the invention.The technical solution adopted in the present invention is: a kind of carry out crossbreeding rice with portable charged fan catch up with powder method, it is characterized in that: rice field row, column spacing is 5 cun, often arranges and only plants male parent or female parent, father, the maternal ratio of planting are 1:3; When father, female parent are bloomed, drying facing to male parent with fan at ridge, evenly falls after the pollen of male parent being blown to maternal top, and half an hour was caught up with powder more once with fan at interval after 1 hour, caught up with powder every day three times.
Described field wide 8 meters and within, father, maternal ratio of planting along field cross direction are 1:6:1.The breeding of hybrid rice breeding of (little field, within the wide 8 meters of field), when father, maternal transplanting, plants male parent on the both sides of long ridge, plants female parent between Tanaka, remaining aisle of need not leaving a blank between father, female parent on a small scale; When father, female parent are bloomed, ridge while with fan facing to male parent blowing, ensure that the pollen of male parent enough blows between Tanaka by wind-force, but be no more than the ridge on opposite farthest, ensure that the pollen of male parent evenly falls after blowing to maternal top, take a round just can complete around ridge with fan when catching up with powder and catch up with powder.
More than described field wide 8 meters, plant male parent 6 arrange along field cross direction, maternal 18 arrange, empty row, and male parent 6 arranges, maternal 18 row, sky row, by that analogy, and empty col width 0.4-0.6 rice.Be applicable to the breeding of extensive breeding of hybrid rice.
Beneficial effect:
1, it is convenient that the charging fan that the present invention utilizes has charging, the advantage that easy to carry, easy to use, wind speed is controlled, wind direction is controlled, very conveniently uses in field.
2, in the present invention, hybrid rice father, female parent are planted concentrated, facilitate field rich water quality management, are applicable to later stage father, maternal unified harvesting simultaneously.
3, save time, saving of labor, convenient and swift, reduce labour intensity and labour cost, workable.If the breeding of hybrid rice of (little field, within the wide 8 meters of field) is bred on a small scale, only need installed rows travelling wheel below charging fan base, just can pushing away (drawing) charging fan on ridge, run a circle, catching up with powder without the need to going to the field just can complete; If produce upper extensive breeding of hybrid rice breeding, be separated by between two aisle 4 meters, and the common interval in powder method between two aisle of catching up with is 2 meters.What that is complete equal size field catches up with powder, the present invention the distance of process only have other to catch up with the half of powder method.Charging fan wind-force is powerful simultaneously, it is thorough that powder falls apart, catch up with powder only to need one time at every turn, do not need to repeat back and forth to catch up with powder, catch up with powder people to reduce again half on the basis of the above through distance, that is, catch up with powder by charging fan, catch up with powder people at every turn in field the distance of process be reduced to that other catch up with powder method 1/4, significantly reduce the labour intensity catching up with powder people.
4, catch up with powder people can control the wind direction of charging fan, fan is adjusted to the basic surface thereof 15-45 degree at male parent height, evenly drop on maternal column cap after allowing the pollen of male parent waft, improve Pollination Effect, improve outcrossing seed-setting rate.The method, for because of the not obvious and not good effect of having greatly improved of Pollination Effect that is that cause of father, female parent strain High Defferential, fully can improve Pollination Effect.Charging fan tilts upward and pollen can be blown to maternal top, overcomes that other producing method for seed rely on father completely, female parent strain High Defferential completes weak point existing for the pattern of pollination.
5, avoid artificially colliding male parent, cause pollen to be wasted.No matter be that dragline type catches up with powder, artificial bamboo pole catches up with powder or vertical row to catch up with powder method to bamboo pole, human body, rope and bamboo pole all can produce collision to male parent fringe portion, cause pollen to be wasted.Especially at male parent full-bloom stage, this artificial collision, waste pollen then more obvious.By charging fan, catching up with in powder process, only needing to catch up with powder people to run one time at ridge or manually catch up with on the aisle of powder, do not need same paddy rice directly to contact, reduce the probability of waste pollen.Inclination 15-45 degree is to blowing up paternal pollen simultaneously, also greatly reduces the situation of paternal pollen waste, improves the availability of paternal pollen.
6, alleviate the injured to father, maternal root, increase the utilization of paternal pollen.No matter be that dragline type catches up with powder, artificial bamboo pole catches up with powder or vertical row to catch up with powder method to bamboo pole, repeatedly step on back and forth owing to catching up with powder people, the damage of father, maternal root system can be caused, thus affect the absorption of paddy rice at the florescence to liquid manure, decrease effective pollen amount of male parent to a certain extent, reduce the vigor of pollen, also injured is caused to female parent simultaneously, affect female parent to bloom, reduce the probability of maternal column cap pollination.And portable charged fan catches up with powder method to catch up with powder method to compare with other, in small-scale (little field, within the wide 8 meters of field) breeding of hybrid rice reproductive process in, powder work is caught up with to complete on ridge, the possibility that people, fan directly do not contact with paddy rice, has stopped the damage artificially caused father, maternal root system; In production in extensive breeding of hybrid rice reproductive process, the distance of catching up with powder people to walk about in field is reduced to 1/4 of additive method, does not need fan directly to contact with paddy rice simultaneously, alleviates the severe degree of catching up with powder people to move in field.These factors greatly reduce the damage artificially caused father, maternal root system, guarantee father, the normal growth at maternal florescence, relatively add the vigor of paternal pollen amount and pollen, ensure that maternal normal flowering habit.
7, reduce the quantity in aisle, field, improve the utilization rate in soil.Catch up with powder method to compare with other, the aisle, field that portable charged fan catches up with powder method to use only needs the half of additive method, does not even need aisle, improves the service efficiency in soil fully, improves unit are hybrid seed yield.
8, portable charged fan catches up with powder method to be fall after paternal pollen being blown heaven in flakes by charging fan, the Pollination Effect ratio uniform of maternal unit are, can not bloom too early because of some areas a few strain male parent, excessively slow, pollen density is few or Pollen Activity is weak and cause neighbouring female parent to award less than powder, affects outcrossing.
