Description
Technical field
The invention belongs to rice cultivating technique fields, and in particular to a kind of rice morning fringe inhibitor and its application.
Background technique
Rice morning fringe refers to rice stem during nursery, just has begun ear differentiation, after rice transplanting, less than heading
When, just the phenomenon that the heading of booting ahead of time.Rice morning fringe is that stem is first eared, and plant height becomes short, and fringe becomes smaller, stem booting
Also in tiller, tiller number is not reduced side stem, and spike of rice generally becomes smaller, and it is late that heading has morning to have, irregular.
It is improper that the reason of rice morning fringe, has plenty of cultivation technique, and some are climatic factors, has irresistible property.Such as exist
The product containing steroids is used for multiple times in the seedling cultivation of rice middle and later periods, stimulates rice seedlings reproductive growth, may result in rice morning
Fringe；Application rate is excessive when seedling cultivation of rice, and rice shoot is crowded and excessive growth, can result in premature heading；Since preceding crop such as receives at the originals late
Rice seedling age is too long because caused by, can result in rice premature heading.If rice seedling, meet the harm of continuous thermal extremes with
Afterwards, rice seedlings may appear in is transferred to reproductive growth in advance on seedbed, just will appear early fringe after transplanting；Rice seedling is excessive
Arid can result in rice and shift to an earlier date ear differentiation, form early fringe.
Traditional remedial measure mainly has: (1) applying booting in time at tiller stem booting initial stage in the rice field for having early fringe to occur
Fertilizer；(2) discovery has the rice field of premature heading, can spray the growth promoting type foliar fertilizer containing humic acid in rice tiller stem booting, promote
Big fringe is formed into tiller stem；(3) before and after the heading of rice tiller stem, potassium dihydrogen phosphate is sprayed, promotes eary maturity of rice.These measures be all
Crop field after shoot transplanting equipment carries out, and not only takes a lot of work laborious, but also produce little effect.
Summary of the invention
In view of this, reducing or preventing rice morning fringe existing the purpose of the present invention is to provide a kind of rice morning fringe inhibitor
The generation of elephant, it is ensured that normal growth and development after rice seedling transplanting reduces production loss caused by due to early fringe occurs.
In order to achieve the above-mentioned object of the invention, the present invention the following technical schemes are provided:
The present invention provides a kind of rice morning fringe inhibitor, the effective components including following mass concentration: 0.4~0.6g/L
