Abstract
The present invention discloses a control method of lodging for direct seeding-rape by using seed dressing with uniconazole, comprising the steps of preparing a liquid medicine by uniconazole technical and water with the ration of 1 : 200000 to 1 : 40000, seed dressing with a weight ration of liquid medicine and seeds between 1 : 8 to 1 : 12, sunning and seeding. The invention has the advantages of labor saving, cost saving, simple and convenient operation, solves the problems of poor security, low survival rate and poor height control effect caused by the seed dressing with paclobutrazol, effectively improves the lodging resistance of rape and increases the output, thereby providing good economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of method of direct-sowing rape control lodging, particularly a kind of method of utilizing uniconazole P seed dressing control lodging for direct seeding-rape.
Background technology
In recent years, along with a large amount of transfers of rural laborer, the direct-sowing rape development is rapid, but because direct-sowing rape density height, plumular axis easily elongates, and root system is pricked shallow down, and the later stage easily lodges, the not high shakiness of output.Though some areas are also used paclobutrazol to dress seed and controlled lodging, because the paclobutrazol drug effect is heavy, poor stability often causes the rape emergence rate to descend, and planting percent is on the low side, and then influences output and benefit.Also there are some areas to attempt using uniconazole P to spray and control lodging for direct seeding-rape in seedling stage (tri-leaf period), but this method is because in seedling spraying, can only control height, can not control the density of emerging, and it is limited to control high effect, and the lodging resistance of rape remains further to be improved, and effect of increasing production is desirable not to the utmost, increase operational sequence simultaneously, increase labour costs.
Summary of the invention
For overcoming the deficiencies in the prior art part, the invention provides a kind of method of utilizing uniconazole P seed dressing control lodging for direct seeding-rape, to improve the lodging resistance of rape, increase the output of rape.
The technical solution adopted for the present invention to solve the technical problems is: former medicine of uniconazole P and water are mixed with 1: 20000～40000 times soups, and soup and seed are dressed seed by 1: 8～12 weight ratio, dry the back sowing.
Beneficial effect of the present invention is: saving of labor's abridged edition, simple and easy to do has solved the paclobutrazol seed dressing, seed sprouting poor stability, the problem that planting percent is low; Solved in seedling stage (tri-leaf period) and sprayed uniconazole P, controlled the problem of high weak effect; Improve the lodging resistance of rape effectively, increased the output of rape, had good economic benefit and social benefit.
Embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment one:
5% commercial uniconazole P is mixed by 1: 1000 weight ratio with water, be mixed with 1: 20000 times of soup; The soup and the seed that are mixed with are dressed seed by 1: 12 weight ratio, after drying, sow with the conventional seed planting amount.Adopt the described method of present embodiment, its planting percent descends to some extent than the clear water sowing, but the seed dressing of the paclobutrazol of ratio 1: 20000,1: 30000 and 1: 40000 times of liquid is significantly improved; Seedling density descends to some extent than the clear water seed dressing, but the sowing of the paclobutrazol of ratio 1: 20000,1: 30000 and 1: 40000 times of liquid also is significantly improved; Quality indexs such as the rhizome of 7 leaf phase rice shoots is thick, height of seedling and single-strain fresh weight are significantly improved than the clear water seed dressing, than the paclobutrazol seed dressing of 1: 20000,1: 30000 and 1: 40000 times of liquid make moderate progress (seeing Table 1).Adopt the described method of present embodiment, it than the declining to a great extent of clear water seed dressing, also has obvious reduction than 1: 20000,1: 30000 and the paclobutrazol sowing of 1: 40000 times of liquid and the uniconazole P that sprayed tri-leaf period 1: 20000 in the individual plant in rape maturing stage lodging generation ratio; Individual plant effective angle fruit, every seed number per pod, thousand kernel weight and output have significantly increase than the uniconazole P that sprayed 1: 20000 in clear water seed dressing, tri-leaf period; Though individual plant effective angle fruit, every seed number per pod and thousand kernel weight, having slightly than the paclobutrazol sowing of 1: 20000,1: 30000 and 1: 40000 times of liquid increases or remains basically stable, and output obviously improves (seeing Table 2).
Embodiment two:
The commercial former medicine of 5% uniconazole P is mixed by 1: 1500 weight ratio with water, be mixed with 1: 30000 times of soup; The soup and the seed that are mixed with are dressed seed by 1: 10 weight ratio, after drying, sow with the conventional seed planting amount.Adopt the described method of present embodiment, its planting percent descends to some extent than the clear water sowing, but the seed dressing of the paclobutrazol of ratio 1: 20000,1: 30000 and 1: 40000 times of liquid is significantly improved; Seedling density descends to some extent than the clear water seed dressing, but the sowing of the paclobutrazol of ratio 1: 20000,1: 30000 and 1: 40000 times of liquid also is significantly improved; Quality indexs such as the rhizome of 7 leaf phase rice shoots is thick, height of seedling and single-strain fresh weight are significantly improved than the clear water seed dressing, than the paclobutrazol seed dressing of 1: 20000,1: 30000 and 1: 40000 times of liquid make moderate progress (seeing Table 1).Adopt the described method of present embodiment, its individual plant in the rape maturing stage lodges the generation ratio, declining to a great extent of clear water seed dressing also has obvious reduction than 1: 20000,1: 30000 and the paclobutrazol sowing of 1: 40000 times of liquid and the uniconazole P that sprayed tri-leaf period 1: 20000; Individual plant effective angle fruit, every seed number per pod and thousand kernel weight have significantly increase than the uniconazole P that sprayed 1: 20000 in clear water seed dressing, tri-leaf period; Though individual plant effective angle fruit, every seed number per pod and thousand kernel weight, having slightly than the paclobutrazol sowing of 1: 20000,1: 30000 and 1: 40000 times of liquid increases or remains basically stable, and output obviously improves (seeing Table 2).
