Abstract
According to the requirement of high yield, all nutrients for the whole growth process of early rice or late rice are compounded scientifically with natural nutrient carrier and through modern fertilizer producing process, special large-grain or bar compound fertilizer is produced. The special compound fertilizer is applied completely before the transplantation of rice and mixed with soil through tillage process, and after that no topdressing is applied.
Description
The present invention relates to a kind of fertilizer compounding process and fertilizing method that is suitable for paddy rice, paddy rice is only used a fertilizer in one season can satisfy the required in life nutrition of paddy rice.
Fertilizer practice is the important component part of rice cropping system.China is maximum in the world Rice Production state, and at the fertilization of rice technical elements, China scientific worker has set up many kinds of fertilizer practices, has played crucial effect to improving China's rice yield.To the seventies, China's fertilizer type increases, and particularly chemical fertilizer is widely-used, and the fertilizer of using in China's Rice Production is main by application of organic fertilizers, then to use chemical fertilizer.The scientific worker is according to the requirement of crop to fertilizer, guarantee a season paddy rice requirement of lasting balanced nutrients in life, requirement accomplishes that early stage is not long suddenly, not early ageing of later stage, therefore, the fertilizer practice of research is the method for applying fertilizer stage by stage, promptly combines with topdressing with base manure, generally make base manure, and other quick-acting chemical fertilizer of simple substance is as topdressing with farm manure, green manure and slow-releasing chemical fertilizer and volatility nitrogenous fertilizer etc.Mix at base manure and the branch that topdresses, 40～60% nitrogenous fertilizer is made base manure, and 60～40% nitrogenous fertilizer topdresses, and phosphate fertilizer is generally made base manure, generally is that organic potassic fertilizer is made base manure to potash fertilizer, and chemical potash fertilizer topdresses; To topdressing, according to upgrowth situation and the nutritional need of crop, use at different growth times, be divided into tillering fertilizer, ear manuer and granulated fertilizer etc.These paddy rice requirements of topdressing to different growing way types and different times are not quite similar, sometimes because of using the improper paddy rice underproduction that causes.
China double cropping of rice area peasant adopt a kind of be accustomed to way promptly about 50% nitrogenous fertilizer and phosphate fertilizer use as base manure, about 50% nitrogenous fertilizer and whole potash fertilizer are in inserting back 5～7 heaven-made tillering fertilizer top applications.Present widely used paddy rice compound fertilizer also is by the base manure and the way of combining of topdressing, the method of this top application of topdressing at the tillering fertilizer in paddy rice fertility early stage because nitrated, nitrogen volatilization and loss etc., nitrogenous fertilizer is lost in a large number, influenced the utilization ratio of nitrogenous fertilizer, also polluted environment.Therefore set up a kind of both simple to operate, be easy to generally to promote but the fertile consumption reduction of province is arranged, the novel fertilization of rice technology of saving cost is very necessary.
The present invention is to provide the compounding process of a kind of double cropping of rice once whole-layer fertilizer applying method and compound fertilizer special in purpose, provide the materialization product for promoting the double cropping of rice once whole-layer fertilizer applying method, thereby make Rice Production fertilising process oversimplify, simplify fertilizer application frequency, reduce recruitment, can reduce the fertilizer loss again, improve utilization rate of fertilizer, save production cost, realize the volume increase of double cropping of rice big area balance.
Realize that principle of the present invention is, according to double cropping of rice early rice or the requirement of late rice output, required main nutrient is in life once prepared, add the natural nutrient carrier,, make the fertile or bar-shaped fertilizer of macrobead fertilizer nutrient absorption and maintenance, once apply in the soil, nutrient slowly discharges in macrobead fertilizer or the bar-shaped fertilizer, has so both reduced fertilizer loss, has guaranteed nutrient supply again.
Content of the present invention is: the compounding process of double cropping of rice once whole-layer fertilizer applying method and compound fertilizer special; be with paddy rice main nutrient in life; be that its available nutrient total amount is 30～45% fertilizer and trace element; with 5～10% natural nutrient carrier; by stirring; the granulation supervisor is made macrobead or bar-shaped compound fertilizer special, before rice transplanting in disposable being manured into soil.Comprise full nitrogen nutrient content 18～23% in the available nutrient total amount, effectively P
2O
53～7%, water-soluble K
2O is 9～15%; Degree of lacking according to different soils type trace element; as go into trace element; with fertilizer, trace element etc.; add the natural nutrient carrier,, make macrobead or Rod shaped fertilizer as zeolite, wilkinite, sepiolite, glaukonine, sulphur, medical stone etc.; particle diameter is generally 3mm～5mm; in being manured into soil, mix and stir when plowed soils, this fertilizer has slow releasing function.
Advantage of the present invention be (1) with two season early rice or the required in life main nutrient of late rice all be formulated in the special-purpose fertilizer of single fertilization method, once apply and guarantee one season of paddy rice fertilizer nutrient needs, no longer implement other program of topdressing, saving man-hour; (2) add the natural nutrient carrier in the fertilizer formula, can control fertilizer slow release, reduce and run off and volatilization, save fertilizer, reduce environmental pollution; (3) can add an amount of trace element according to the different soils type, replenish the soil nutrient deficiency, bring into play fertilizer efficiency to greatest extent, make high crop yield, reach the purpose of high-yield and high-efficiency.
Embodiment: this example is one of them representative instance, summary of the invention is not limited.Geographic reddish yellow mud paddy soil in the Hunan, Hunan, soil fertility is above the average, and the per mu yield of this soil double cropping of rice early rice reaches 500kg, according to the present situation of Rice Production, determines the quantity of mu fertilise, and then fertilizer formula is that full N is 16～18%, effectively P
2O
5Be 5～6%; water-soluble potassium is 9～12%; total available nutrient is 33～39%; add the trace element contain the soil disappearance such as Zn, B, Cu, Si; mix, stir with the wilkinite of natural nutrient carrier 5～10%, sepiolite, medical stone etc., make macrobead or Rod shaped fertilizer, use 45～60 kilograms for every mu by fertilizer processing technology and equipment; plowed soils before rice transplanting is in being manured into soil.After inserting paddy rice, no longer other fertilizer need be used, the early rice nutritional need in one season can be satisfied.
Claims (3)
1. one kind is suitable for double cropping of rice once whole-layer fertilizer applying method and compound fertilizer special compounding process; it is characterized in that the main nutrient of paddy rice in one season; be that its available nutrient total amount is the natural nutrient carrier of 30～45% fertilizer and trace element and 5～10%; by stirring, granulation supervisor; make macrobead or bar-shaped composite fertilizer special; particle diameter is generally 3～5mm, before rice transplanting in disposable being manured into soil.
