Description

Rice on honda fertilizing method

Technical field:

The present invention relates to fertilization of rice administrative skill field, be specifically related to a kind of rice on honda fertilizing method.

Background technology:

Paddy rice originates in Tropical Asian, after China widely plants, propagates into all over the world gradually.According to diverse ways, paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.China scientist Yuan Longping makes a great contribution to the research of hybrid rice, is described as " father of hybrid rice ".The grain of rice that paddy rice is tied claims rice or rice after shelling.Nearly half population, all take rice as food in the world.The eating method of rice is varied, has rice, congee, rice cake, rice cake, rice noodles rice wine etc.Paddy rice, except edible, can also be made wine, refine sugar and make the raw material of industry, and rice husk, rice straw also have a lot of use.China paddy rice main producing region is mainly the Northeast, the Yangtze river basin, Pearl River Delta.Paddy rice institute knot is paddy in fact, claims rice or rice after shelling.Belong to direct economy crop.Or the mankind's staple food.

And Rice Growing needs multiple inorganic nutritive element, wherein maximum is nitrogen, phosphorus, potassium, fertile and unbalanced but each growing stage is inhaled, if irregular like this amount to fertilizer processes, will cause the situations such as the underproduction, death, brings direct economic loss.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency a kind of rice on honda fertilizing method that a kind of method is reasonable, enforcement is convenient, simple to operate is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

Rice on honda fertilizing method, is characterized in that: comprises the following steps,

Step 1, the short keyholed back plate reason of fetilizer for tillering: short tiller, the fetilizer for tillering of nitrogenous fertilizer total amount 30% will impose at twice, for the first time after turning green, in conjunction with 3cm water layer, heat short tiller management, 3/4 amount that imposes immediately fetilizer for tillering nitrogen is that mu chases after urea 4.73kg, make fertilizer efficiency reaction contain i.e. 6 leaves in tiller leaf position, for the second time by 1/4 fetilizer for tillering of remainder mu chase after urea 1.58kg and regulate and control to topdress according to rice seedling growing way,, Ye Sehuang rare to rice seedling, the short place of rice strain execute more; Control tiller, for ineffective tillering after controlling 8 leaves occurs, at 6 Leaf-Age-Periods, finish using of fetilizer for tillering, when stem tiller number reach plan stem number 80% time be that the phase is ended in effective tiller, in conjunction with dry field, control ineffective tillering, shine and occur fine fisssure to earth's surface, make colony's leaf look start to move back light, tillering speed slows down, and new tiller stops occuring as suitable;

The short control of step 2, ear manuer: grow half and execute ear manuer falling 2 leaves, in conjunction with intermittent irrigation 4cm water layer management, immediately 20% of Nitrogen Top Dressing total amount mu chase after urea 4.35kg, potash fertilizer total amount 30% mu chase after potassium sulfate 3.3kg; Guarantee that grain husk spends idiophase and meiosis stage and see fertilizer efficiency, can urge flower, protect flower, increase grain number per spike, short root, strong stalk resistant to lodging, it is yellow that now leaf look takes off the existing jointing that fades out, and the highest stem tiller has been controlled at 1.2-1.3 times of expection spike number, and invalid tiller tapers off, if 2 leaf phases did not occur that jointing was yellow, invalid tiller is not controlled completely, can delay when mirror leaf reveals point and impose ear manuer, guarantees the photosynthetic advantage of milk ripe stage functional leaf;

Step 3, the short control of granulated fertilizer: from beginning fringe to full heading time, this phase ineffective tillering is substantially become feeble and die and is tended towards stability, and complete expection plan ear stem number, management key is to support Gen Baoye, improve photosynthetic efficiency, enrich seed, to determine the output key period, in conjunction with the dry wet 4cm water layer management of irrigating, according to paddy rice growing way, Nitrogen Top Dressing total amount 10% i.e. mu imposes urea 2.17kg, now slow down wax ripeness end to stage of yellow ripeness blade take off light, prevent early ageing, to the maturing stage, still can keep 2 more than leaf photosynthetic greenery is keys of the short control of granulated fertilizer.

Beneficial effect of the present invention is: very clear of above-mentioned method statement, in the required work of doing of each period, and needed fertilizer, consumption etc., particularly in each time period, be described later in detail, staff is just difficult to make mistakes in the process of the method work according to above-mentioned like this, and can increase work efficiency.The inventive method is reasonable, enforcement is convenient, simple to operate.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

Rice on honda fertilizing method, is characterized in that: comprises the following steps,

Step 1, the short keyholed back plate reason of fetilizer for tillering: short tiller, the fetilizer for tillering of nitrogenous fertilizer total amount 30% will impose at twice, for the first time after turning green, in conjunction with 3cm water layer, heat short tiller management, 3/4 amount that imposes immediately fetilizer for tillering nitrogen is that mu chases after urea 4.73kg, make fertilizer efficiency reaction contain i.e. 6 leaves in tiller leaf position, for the second time by 1/4 fetilizer for tillering of remainder mu chase after urea 1.58kg and regulate and control to topdress according to rice seedling growing way,, Ye Sehuang rare to rice seedling, the short place of rice strain execute more; Control tiller, for ineffective tillering after controlling 8 leaves occurs, at 6 Leaf-Age-Periods, finish using of fetilizer for tillering, when stem tiller number reach plan stem number 80% time be that the phase is ended in effective tiller, in conjunction with dry field, control ineffective tillering, shine and occur fine fisssure to earth's surface, make colony's leaf look start to move back light, tillering speed slows down, and new tiller stops occuring as suitable;
