Abstract
The present invention relates to Rice Cropping technical field, the method for a kind of Rice In Drought Rice Nursery ground matrix seedling specifically, comprise (1) rice seedling bed and select to prepare with seedbed; (2) matrix prepares; (3) presoaking and germinating and (4) are sowed and seedling management step; In the inventive solutions, because seedbed is the compacted zone of 4 ~ 5cm, paddy rice root system in process of growth cannot penetrate compacted zone, all root systems all grow in matrix, be easy to rice shoot to pull up when pulling up seedlings, when there will not be traditional seedling, root system penetrates deep layer and causes pulling up seedlings and damage the problem of a large amount of rice shoot root system; Compacted zone is at 1.3 ~ 1.4g/cm
-3in density range, the most of root system of rice seedling not easily penetrates and penetrates deep soil, but moisture, oxygen and nutritive element can move freely, ensure the normal growth of rice seedling, very little to root system damage when pulling up seedlings, survive after transplanting and be more prone to, reach and early send out early long, efficient effect.
Description
Technical field
The present invention relates to Rice Cropping technical field, the method for a kind of Rice In Drought Rice Nursery ground matrix seedling specifically.
Background technology
Paddy rice nursery method mainly contains the large type of water-raised seedling, dry rice seedling and watery ricenursery 3.Watery ricenursery subject matter is long-term waterflooding, and oxygen in soil is not enough, and rotten kind of seedling rot is serious, the easy excessive growth of rice shoot, and seedling quality is poor, and the method is only applied before the seventies in last century.Afterwards, be improved to water-raised seedling, develop dry rice seedling again subsequently; Water-raised seedling and dry rice seedling are the main method of raising seedling of the current Rice Production of China.
China's dry rice seedling technology is the raising rice seedlings technology that eighties of last century the seventies is introduced by Japan.Dry rice seedling is in whole seedling process, and soil conservation is moistening, and rice shoot is healthy and strong, well developed root system, and early a precocity, water saving abridged edition save rice seedling bed and the large feature of seedling age elasticity to have early sowing.And dry rice seedling has stronger physiological dominance: Dry Breeding Seedlings cell leakage is lower, cell viability is comparatively strong, cell bound water content and osmotic pressure high, retention ability is strong, and resistance against disadvantage is strong.Dry rice seedling has been carried out drought and has been educated drought pipe, have that leaf emergence rate is slow, rice shoot is sturdy, Bai Genduo, evident characteristics such as that white root rate is high, individual plant is tillered is many, tillering node rate is high, rice shoot dry matter content is high, and dry rice seedling can prevent the dead seedling of low temperature in early spring effectively, emergence rate and planting percent high.Turn green after shoot transplanting equipment fast, early send out early kept burning day and night aobvious.Dry rice seedling realizes rice high yield, stable yields, a technology increasing income, and test for many years shows, dry rice seedling than the average mu volume increase of water-raised seedling about 10%.
Tradition paddy drought seedling method selects suitable nonirrigated farmland, and hack of turning over, executes organic and inorganic fertilizer, after planting covers with soil, water.But, tradition paddy drought seedling method is directly in nonirrigated farmland soil farming seedling, rice shoot root system penetrates deep soil arbitrarily, cause rice shoot root system to fracture when pulling up seedlings or damage serious, and time-consuming taking a lot of work of pulling up seedlings, bring difficulty of pulling up seedlings, there is survival rate after causing shoot transplanting equipment land for growing field crops low simultaneously, rice shoot time of turning green is long, affects paddy rice and early sends out the early problem such as long.
Summary of the invention
The present invention is directed to traditional dry rice seedling seedling taking difficulty, hinder the root series of problems caused such as serious, the method for a kind of nonirrigated farmland matrix seedling is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of method of Rice In Drought Rice Nursery ground matrix seedling, comprises the steps:
(1) rice seedling bed is selected to prepare with seedbed: select the nonirrigated farmland of fertile soil, irrigation and drainage convenience, convenient management as dry rice seedling field, seedbed is done by 1.5 ~ 1.7m width, face, seedbed is higher than passageway 5 ~ 10cm, smooth compacting, make seedbed be middle high, surrounding is low, middle to surrounding be 8 ~ 12 degree domatic, seedbed compacting depth 4 ~ 5cm, bottom soil density is 1.3 ~ 1.4g/cm
-3;
Compacted zone is at 1.3 ~ 1.4g/cm
-3in density range, the most of root system of rice seedling not easily penetrates and penetrates deep soil, but moisture, oxygen and nutritive element can move freely, and ensures the normal growth of rice seedling.
(2) matrix prepares: dryland soil is through air-dry, the particle being ground into diameter 2 ~ 3mm is for subsequent use, then mix for dryland soil 65%, fertilizer 10%, peat 20% and vermiculite 5% by volume, the acid adjustment of acid adjustment material is adopted to be 5.0 ~ 5.5 to substrate pH, then the matrix prepared is laid on seedbed, thickness 4 ~ 7cm;
When actual seedling, in matrix, can add according to the fertility of soil the fertility that a certain amount of fertilizer improves matrix.
(3) presoaking and germinating: seed rice is put into clear water, add the carbendazim sterilization that mass concentration is 0.35%, seed soaking 24h, then seed rice is pulled out clean, put into clear water and soak 24 ~ 72h, seed rice is fully absorbed water, then temperature be 28 ~ 35 DEG C, humidity be the condition of 90% under vernalization, before seed rice cut, temperature controls at 32 ~ 35 DEG C, temperature is controlled at 28 ~ 30 DEG C after cut, stops vernalization when root grows to 0.2 ~ 0.6cm after vernalization 24h;
(4) sowing and seedling management: by the mode of sprinkling irrigation, matrix is fully absorbed water to before sowing saturated, then will the seed rice of bud have been urged to broadcast equably in matrix, vernalization seed rice 150 ~ 200g is sowed by every square meter according to variety type and length of time rice seedlings grow length, cover seed rice by matrix again, cladding thickness is about 5 ~ 8mm.
Compared with prior art, Advantageous Effects of the present invention is:
(1) in the inventive solutions, because seedbed is the compacted zone of 4 ~ 5cm, paddy rice root system in process of growth cannot penetrate compacted zone, all root systems all grow in matrix, be easy to rice shoot to pull up when pulling up seedlings, when there will not be traditional seedling, root system penetrates deep layer and causes pulling up seedlings and damage the problem of a large amount of rice shoot root system; Compacted zone is at 1.3 ~ 1.4g/cm
-3in density range, the most of root system of rice seedling not easily penetrates and penetrates deep soil, but moisture, oxygen and nutritive element can move freely, and ensures the normal growth of rice seedling;
(2) in the present invention, matrix is made up of loose peat, dryland soil, vermiculite and fertilizer, pH is 5.0 ~ 5.5, suitable especially Root Growth of Rice, rice shoot root growth is in matrix, very little to root system damage when pulling up seedlings, survive after transplanting and be more prone to, reach and early send out early length, efficiently effect;
