Description
Technical field
The present invention relates to a kind of rape rice shoot processing technology field, especially a kind for the treatment of process of rape blanket appearance seedling, belongs to agricultural technology field.Relate to and utilize common urea and growth regulatory substance Plant hormones regulators,gibberellins, be configured to certain density solution and spray rice shoot processing, to promote early to live after the land for growing field crops machine transplanting of rice of rape blanket appearance seedling.
Background technology
The planting patterns that culturing and transplanting seedlings rape adopts seedbed to grow seedlings, manually transplant always, this mode use artificial many, labour intensity is large, production efficiency is low.2009～2014 Yangzhou Universitys combine with Nanjing agriculture mechanize institute of the Ministry of Agriculture explores the novel cultivation mode of rape transplanting, combine with agronomy by agricultural machinery, cultivate rape blanket shape seedling, and carry out rape production mechanization with the rice seedling transplanter of improvement and plant, obtained remarkable break-throughs, having developed at present scientific research model machine can be at field effective operation.
Although being applicable to mechanize, blanket shape seedling transplants at a high speed, but because seedling density is large, Miao Ti little, generally only has 4 blade left and right, the few 4-5 leaf of dish seedling of educating than production ordinary method, therefore blanket appearance seedling machine is planted behind land for growing field crops, to shorten as far as possible seedling-slowing stage, promote early alive, thus effective vegetative period before extending the winter, before increasing the winter, increment contributes to more bud differentiation, is conducive to so finally obtain high yield.Blanket appearance seedling will be lived and have soon two requirements after being transplanted: the one, and the anti-ability of wound of planting of requirement rice shoot is strong, and the 2nd, rice shoot can send new root in time.Both relevant with carbon, nitrogen level in seedling body.The rooting ability of dish seedling depends primarily on the nitrogen level in body, because the growth of root must be take the nitrogenous compound such as protein, nucleic acid as basis, it is high that dish seedling body includes nitrogen level, and root cells propagation is fast, and rooting ability is strong.So improve rooting ability, must improve the nitrogen level of seedling body.But the dish seedling that nitrogen level is high, water content is high, and seedling is tender, and anti-planting hindered ability, plants rear blade and easily dries up.As for carbon element level, rooting ability is also had to suitable effect, because the main source of its energy while being root growth, it has also participated in the material composition of root, and but, to be not so good as nitrogen level close with the relation of rooting ability for it.Dish seedling anti-planted the carbon element level that overstrain is decided by seedling body, and carbon element level is high, and enchylema osmotic pressure is large, and bound water content is high, and seedling body is always strong, runs into Exposure to Sunlight wind after cultivation, and blade is difficult for withered.So, improve the anti-ability of wound of planting, must improve the carbon element level of seedling body.But this seedling rooting ability is poor, be difficult for alive.Therefore regulate carbon nitrogen equilibrium in plant body, make that machine transplanting of rice rice shoot is anti-plants overstrain and rooting ability is all more intense, rice shoot can be lived as early as possible, what kind of adopts urge control means and seem very crucial.
Because rape blanket appearance seedling density is larger, general density is at 5000～6000 strains/m2, and the blanket appearance seedling in seedling-cultivation plate generally will be controlled its growth, as carried out Dressing by uniconazole, reduces collar length; Rich water consumption can not be too much, otherwise plant water content is high, and anti-planting hindered ability etc.The Chinese invention patent application that related content can be 201210418971.9 referring to application number.Be not easy to send in time new root through controlling the blanket appearance seedling of processing after being transplanted to land for growing field crops, be difficult to fast quick-recovery growth, even occur that stiff seedling do not find to resemble.
Summary of the invention
The object of this invention is to provide the rice shoot treatment agent that can live as early as possible after being applicable to promote rape blanket appearance seedling to plant.This treatment agent configuration and easy to use, can effectively promote alive as early as possible of machine transplanting of rice rice shoot.
Technical scheme of the present invention is as follows: an a kind of blanket treatment agent in strong sprout that is applicable to promote that rape machine transplanting of rice rice shoot is early lived, formula is: Plant hormones regulators,gibberellins 1.25mg/L, common urea (N, 46%) 40g/L, potassium primary phosphate 150mg/L, four water-calcium nitrate 950mg/L, saltpetre 600mg/L, boric acid 3.0mg/L, supplies moisture and is fully dissolved to 1L.
Rape blanket appearance seedling treatment agent application method of the present invention is, machine is planted first 3～7 days, and every square metre of blanket shape seedling dish sprays 600ml.
Applied chemistry method of the present invention is processed blanket appearance seedling for 3～7 days before machine is planted, carbon element level and nitrogen level in the blanket appearance seedling body that can make to cultivate are all higher, can promote the early work of rice shoot that machine is planted, promote the effectively growth fast before the winter, thereby guarantee that machine transplanting of rice rice shoot can obtain high yield.It is low, effective that the present invention has input, and the feature that operation is simple is to be adapted at the front more satisfactory rice shoot treatment agent that rice shoot is sprayed of the machine transplanting of rice.Rice shoot surviving rate through treatment agent processing of the present invention is higher, and a recovery growth of living is fast.
Embodiment
Embodiment 1
Adopt the rice shoot treatment agent formula in foregoing invention content, the rape blanket appearance seedling treatment agent of producing 1000ml volume needs Plant hormones regulators,gibberellins 1.25mg, urea 40g, potassium primary phosphate 150mg, four water-calcium nitrate 950mg, saltpetre 600mg, boric acid 3.0mg, supplies moisture and is fully dissolved to 1L.
This test is revived this kind of oily 211(2008 by the authorization of new crop varieties validation board of Jiangsu Province take the cabbage type normal rapeseed kind of Yangzhou University's seed selection) as test materials.In the Chinese invention patent application that is 201210418971 by application number, method is cultivated blanket appearance seedling.Sowing time is on October 5th, 2013, after planting 18 days every square metre spray this rice shoot treatment agent 600ml, be equipped with rice shoot (CK) in contrast without treatment agent processing of the present invention simultaneously, within the 23rd day, on seedling-cultivation plate, carry out sampling and measuring individual plant greenery number, root length, nitrogen content, carbon content, plant fresh weight and dry weight, and carrying out land for growing field crops transplanting in the 23rd day, machine is investigated individual plant greenery number, root length, nitrogen content, carbon content, plant fresh weight, a dry weight and field rate alive on the 7th day after planting.Wherein carbon for nitrogen content elemental analyser (Vario MAX CN, Elementar Co., Germany) measure.
