Abstract
The invention provides an efficient mechanical topdressing method for rice field in a cold region and relates to a mechanical topdressing method. The invention is mainly used for solving the problems that fertilizer in the existing rice seedling transplanting and fertilizing machine absorbs moisture in a topdressing process, moistened fertilizer can easily block a fertilizer applying pipe and normal mechanical topdressing is difficultly carried out and the problems that topdressing frequency is high and topdressing effect is poor in the traditional topdressing process. The efficient mechanical topdressing method for the rice field in the cold region is realized by the following steps: firstly, preparing a bulk blending fertilizer, wherein the bulk blending fertilizer is composed of a quick-acting nitrogen fertilizer and a controlled release nitrogen fertilizer; secondly, the bulk blending fertilizer is applied when a rice seedling transplanting machine is used for transplanting rice seedlings. According to the efficient mechanical topdressing method for the rice field in the cold region, the quick-acting nitrogen fertilizer and the controlled release nitrogen fertilizer are mechanically topdressed in one step when the rice seedlings are transplanted, the problems that fertilizer absorbs moisture, moistened fertilizer blocks the fertilizer applying pipe and normal mechanical topdressing is difficultly carried out are solved, and the bulk blending fertilizer containing the controlled release nitrogen fertilizer is topdressed in one step, so that the requirement of rice on nitrogen from a rice seedling transplanting period to a mature period is met; meanwhile, fertilizer is applied in one step by adopting the rice seedling transplanting and fertilizing machine, so that fertilization is simplified and efficient. The efficient mechanical topdressing method for the rice field in the cold region is applied to the agricultural technical field.
Description
Technical field
The present invention relates to a kind of mechanization topdressing method.
Background technology
Nitrogen is one of critical limitation factor of crop yield raising.How making nitrogen application and crop need nitrogen to match is the focus of studying both at home and abroad.In order to realize high crop yield, the target of nutrition efficient, international plant nutrition research institute has proposed the best nutrient management principle of " 4R ".When fertilising, definite total amount of science; Execute in best period; Select the suitableeest kind; Execute in place.At present, the best nutrient administrative skill that the U.S. is representative of take has in the world realized " 4R " principle substantially, and domestic also there is a big difference.The mechanization degree particularly applying fertilizer in China's Rice Production is minimum, and mostly base manure is to spread fertilizer over the fields behind the whole ground of water, and then rotary tillage, cannot really accomplish the deep placement of nitrogenous fertilizer.Chasing after nitrogen is just top application completely, this fertilization mode causes nitrogen to lose in a large number, and also there is the irregular problem of Term Fertilization in artificially applying fertilizer, cause partial fertilizer excessive or not enough, bring very large difficulty to farmland standardized management, become the key issue that restriction rice yield and nitrogen efficiency further improve.
Although existing rice transplanting fertilizer distributor can carry out machinery, topdress, the easy moisture absorption of urea in the process of topdressing, easily stops up fertilising pipe after fertilizer deliquescence, become the main limiting factor of mechanization top dressing technique application.More crucial, using of rice field ear manuer can only be by manually completing, and this has become the bottleneck problem of Paddy fields mechanization.
Summary of the invention
The object of the invention is in order to solve the easy moisture absorption of existing rice transplanting fertilizer distributor fertilizer in the process of topdressing, after deliquescence, easily stopping up fertilising pipe causes machinery to topdress being difficult to normally carry out, and traditional problem of weak effect often of topdressing, and the cold region rice efficient mechanical topdressing method providing.
Cold region rice efficient mechanical topdressing method is to realize according to the following steps:
One, the preparation of bulk blended fertilizer: bulk blended fertilizer is comprised of instant nitrogenousfertilizer and Controlled Release Nitrogen Fertilizer, instant nitrogenousfertilizer 80kg/ha～120kg/ha, Controlled Release Nitrogen Fertilizer is 60kg/ha～100kg/ha, wherein instant nitrogenousfertilizer is comprised of amidonitrogen, ammonium nitrogen and zinc fertilizer, the mass ratio of ammonium nitrogen and amidonitrogen is 1:(0.9～1.1), in Controlled Release Nitrogen Fertilizer, the mass fraction of nitrogen is 35%～45%, and in zinc fertilizer, zinc element accounts for 0.3%～0.5% of bulk blended fertilizer quality;
Two, use bulk blended fertilizer: in rice transplanting, use bulk blended fertilizer, specifically carry out in the steps below: the bulk blended fertilizer that preparation in step 1 is obtained is placed in the fertilizer groove of rice transplanting fertilizer distributor, rice transplanting fertilizer distributor adopts side deep fertilizing method to apply fertilizer.
First the present invention changes the formulation of fertilizer, the bulk blended fertilizer of no longer directly applying urea or containing urea, and use, contain the bulk blended fertilizer that the instant nitrogenousfertilizer that formed by amidonitrogen, ammonium nitrogen and zinc fertilizer granulation and Controlled Release Nitrogen Fertilizer form, the ratio of this detecting ammonium nitrogen in fertilizer and amidonitrogen is 1:(0.9～1.1), so both can effectively solve the problem of fertilizer deliquescence in the process of topdressing, can effectively control the pH value of rice field water layer again, reduce nitrogen loss; Use simultaneously a certain proportion of Controlled Release Nitrogen Fertilizer (in Controlled Release Nitrogen Fertilizer the quality of nitrogen element account for rice transplanting to the total nitrogen element quality of executing in maturation 25%～40%), 60d～the 90d of the bulk blended fertilizer that the present invention prepares after rice transplanting still can discharge a certain proportion of nitrogen, thereby played the effect of using ear manuer.
Beneficial effect of the present invention: when 1, cold region rice efficient mechanical top dressing technique of the present invention adopts rice transplanting, one-time mechanical chases after the method for instant nitrogenousfertilizer and Controlled Release Nitrogen Fertilizer, has solved and has stopped up fertilising pipe after fertilizer moisture absorption, deliquescence and cause machinery to topdress being difficult to the problem of normally carrying out.2, the method that the present invention's disposable machinery when rice transplanting chases after instant nitrogenousfertilizer and Controlled Release Nitrogen Fertilizer can also reach with tradition and impose the effect that ear manuer is identical, meet the paddy rice demand to nitrogen throughout one's life, no longer impose ear manuer, the real mechanization of having accomplished Paddy fields, adopts rice transplanting fertilizer distributor single fertilization to make simple to operateization of applying fertilizer.Although the Controlled Release Nitrogen Fertilizer that 3 the present invention use can increase cost, to compare with the cost of employing artificially applying fertilizer in traditional Paddy fields process 2～3 times, cost of the present invention does not increase, so this technology does not increase production cost.4, compare with 2～3 top dressing techniques of traditional paddy rice, the present invention's disposable machinery when rice transplanting chases after instant nitrogenousfertilizer and Controlled Release Nitrogen Fertilizer, can improve rice yield 10%～15%, increases by 20 percentage points of utilization rate of nitrogen fertilizer, can make every mu to increase income more than 100 yuan.
