Description
Technical field
The present invention relates to a kind of machine-transplanted rice cultivating seedlings in dry land method.
Background technology
Transplanting is one of the technology of promoting mainly of Rice Production, and the quality of rice shoot is directly connected to plants quality, a quantity of living and colony quality, is the key link that determines output.Be different from hand and plant rice, machine transplanting of rice rice shoot is grown rather than is grown directly upon on seedling bed in seedling dish, due to the poor-performing (matrix seedling is all the more so) of seedling dish water conservation, the non-irrigated seedling-cultivation technique operation easier in machine transplanting of rice seedling that is applicable to hand cultivation rice is larger, and what therefore machine transplanting of rice seedling generally adopted is flood irrigation water-raised seedling pattern.
Practice in recent years shows, machine transplanting of rice rice flood irrigation water-raised seedling technology exists some significantly not enough, the one, and too high, time-consuming to the requirement of seedling plate flatness.If seedling plate flatness is inadequate, while pouring water, there will be deep mixedly, some places have flooded seedling, some places are also not upper, and to water, this problem in large rice seedling bed is more outstanding, and this will cause seedling growth uneven, even do not sprout, the phenomenon such as rotten bud, dry kind, have a strong impact on the quality of seedlings; And high-level seedling plate must, through loaded down with trivial details operations such as " upper water is tested flat ", " a kind of farm tools are flat repeatedly ", also will often be taken off cloth while pouring water to check, water management difficulty is large, time-consuming; The 2nd, while adopting organic substrate seedling, easily there is " floating seedling " phenomenon of seedling blanket emersion seedling dish.Make because seedling raising ground substance adopts agricultural organic waste more, unit weight is low, and the in the situation that of moisture deficit, pour water (flood irrigation), if excessive velocities or water level are too high, will cause the situation of seedling piece emersion seedling dish, and after water level declines, easily lack of water is suffered from drought; The 3rd, upper water speed is slow, and efficiency is low, time-consuming.The 4th, long-term soaked make muddy, the sunken pin of seedling plate, unfavorable farm work.The 5th, water resources consumption is large, and availability is low.Although and the non-irrigated seedling raising method seedling effects such as industrial sprout cultivation, hard place seedling are better, cost is high, is difficult to large area and carries out.
Therefore, explore more light letter, efficiently, the machine transplanting of rice seedling irrigation technique of water saving, abridged edition is imperative.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of machine-transplanted rice cultivating seedlings in dry land method.
The present invention solves the technical scheme that its technical problem adopts: a kind of machine-transplanted rice cultivating seedlings in dry land method, comprises the following steps:
A, seed bed preparation: the dry aeration type seedling plate that does on rice seedling bed, offer seedling ditch, enclose ditch;
B, presoaking and germinating;
C, micro spray irrigation system are installed: stem system, Heavenly Stems and Earthly Branches pipeline and fine-spraying belt are installed on rice seedling bed;
D, balance sowing: comprise balance and sowing;
E, seedling management: look the spray irrigation of rice shoot situation.
Further, Heavenly Stems and Earthly Branches pipeline comprises main and arm, and main two ends are connected with stem system, arm respectively, arm two ends are connected with main, fine-spraying belt respectively, one end of fine-spraying belt is connected with arm, and the other end is drawout laterally, and the end of the other end is tightened with tightrope.
Further, main is the steel wire mesh frame polyethylene compound pipe of 100～120 mm dias, and arm is the polyethylene pipe in 70～90 millimeters of folding footpaths, and fine-spraying belt is the oblique five hole fine-spraying belts in 40～50 millimeters of folding footpaths, and the spraying swath of fine-spraying belt is 3～6 meters.
Further, the method for balance is that laterally pendulum four is arranged seedling dishes, is divided between two two groups, and every group is close to, and is provided with the interval of laying fine-spraying belt between two groups of seedling dishes.
Further, arm and main junction are provided with arm valve, and fine-spraying belt and arm junction are provided with fine-spraying belt valve.
The invention has the beneficial effects as follows: 1, overcome flood irrigation water-raised seedling to the too high deficiency of seedling plate flatness requirement.Owing to being sprinkling irrigation, water droplet, even if seedling plate is smooth not, also there will not be the irregular phenomenon of pouring water from top to bottom, and seedling plate has saved the loaded down with trivial details operations such as " upper water is tested flat ", " a kind of farm tools is flat repeatedly " while making, saved recruitment cost; 2, overcome the deficiency that flood irrigation water-raised seedling there will be " floating seedling " phenomenon.Owing to being sprinkling irrigation, water droplet, while adopting organic substrate seedling, even if seedling blanket is more dry, also there will not be the situation of emersion seedling dish from top to bottom; 3, compared with flood irrigation water-raised seedling, the speed of pouring water is fast, can adopt a small amount of irrigation method repeatedly, avoid seedling plate because soakedly becoming muddy for a long time, fall into pin, plate is hard, the farm work such as convenient laxative; 4, micro spray irrigation belongs to water-saving irrigation technique, and water utilization rate is high, and waste is few; 5, fine-spraying belt installation, use, easy removal, used supporting special coiler, easily moves and take care of, and compared with other sprinkling irrigation equipments, cost of investment is low; 6, irrigation effect is good, and seedling quality is high, and rice shoot regularity is high, and well developed root system, dish are bolted close, and the compatibility of seedling blanket and rice transplanter is good.
