Description
Technical field
The present invention relates to field of agricultural cultivation, particularly relate to Oryza sativa L. and protect tiller increasing fringe high yield fertilizer technology.
Background technology
At present China in rice cropping always custom (on textbook) use and carry out " front rush (base fertilizer+
Dressing of turnning green stage+tillering fertilizer), middle control (late tillering state does not applies fertilizer), rear mend (benefit executes ear manuer) " fertilising skill
Art, from field investigation for many years, observes, this fertilizing method, to rice tillering latter stage, because of Oryza sativa L.
Fertile amount deficiency, it is impossible to maintaining the effective supply of later stage fertilizer, it is green that Oryza sativa L. occurs that blade moves back too early, Ye Seluo
Huang, causes tiller amount not enough, and easily occurs Oryza sativa L. to move back wooden fork phenomenon, and number of productive ear is the most up to standard, causes Oryza sativa L.
The underproduction.
Meanwhile, in Oryza sativa L. " front rush, middle control, mend afterwards " on the basis of fertilizer practice, also two kinds common
Fertilizer practice, one is that early stage executes dressing of turnning green stage, tillering fertilizer more, and the later stage does not execute the method for ear manuer, early stage tiller
Though many, it is too quickly to easily cause Oryza sativa L. early stage growing way, and leaf is black green, and blade is excessive, and field covers, and ventilates
Light transmission is deteriorated, the most susceptible, and the later stage moves back tiller, moves back fringe seriously, is difficult to retain abundant effective fringe,
Cause the Oryza sativa L. underproduction；Two is too much to use base fertilizer (i.e. major part is fertile), the method the most not executing ear manuer,
Early stage is not enough due to upper strata, soil fertility, and performance fertilizer efficiency is poor, and Oryza sativa L. growing way is not enough, and tiller is few, effective fringe
Deficiency, later stage fertility is excessive too quickly, and Later Stage of Rice growing way is in great numbers, remaining green when it is due to become yellow and ripe late-maturing, is more easy to susceptible, because of life
Produce poor effect and the underproduction.
The fertilization of rice technology of above-mentioned three kinds of decades the most commonly used in current rice cropping period, without
Method meets rice cropping needs and adapts to the Oryza sativa L. actual demand rule to nitrogenous fertilizer, fertilizing method not with
Time all enter and reform innovation, cause its each in period fertilizing method optimize not, it is impossible to accomplish water
Rice protects tiller and increases fringe volume increase, the problem that there will be the underproduction on the contrary.
Summary of the invention
In view of this, it is an object of the invention to provide Oryza sativa L. and protect tiller increasing fringe high yield fertilizer technology so that institute
State and can significantly improve rice yield with fertilizer technology.
