Description
Technical field
The present invention relates to fertilizer technology, particularly relate to the long-acting potassium sulfate type Chemical Mixed Fertilizer technology that a kind of sugarcane is special.
Background technology
Sugar is requisite during people live, and sugar is produced significant in Chinese national economy.Sugarcane is the important sugar crop of China, current China cultivation of sugar cane area about 2,000 ten thousand mu, output of sugar about 1,100 ten thousand tons, and its sucrose yield accounts for national sugar industry amount more than 90%, in China's sugar industry is produced, have very important status.
China sugarcane is cultivated mostly in arid hillside fields, and output is lower, and the impact of climate factor is larger.Twentieth century and earlier 2000s, sugarcane purchasing price is extremely low, and cane planting economic benefit is not high, even loses money in the bad weather time, has a strong impact on peasant planting enthusiasm, also has a strong impact on China's sugar industry Sustainable development simultaneously.In recent years, China works out a series of preferential sugarcane grower's policy, as subsidies for growing superior grain cultivators, loan subsidy etc., add that world's Price of Sugar is higher in recent years, thus purchase sugarcane price and also rise thereupon, the benefit that grows cane also progressively takes a turn for the better, cultivation of sugar cane area is stable, rising progressively, but compared with developed countries, China's cane planting economic benefit is still lower, ensure China's sugar industry Sustainable development, improve the road that cane planting economic benefit is certainty.
China's cane planting economic benefit is lower, relevant with several factors, and wherein Term Fertilization is unreasonable is an importance.Mainly there is following problem in current China sugarcane Term Fertilization: one be Term Fertilization often, fertilising cost higher.The sugarcane production cycle reaches 9-12 month, repeatedly will apply fertilizer and could meet sugarcane to nutrient requirement.Generally apply fertilizer 3 times aborning, namely base manure and secondary topdress, and particularly second time is topdressed, because sugarcane has looked higher, apply fertilizer very inconvenient, and labor intensive, thus fertilizer application frequency is reduced, cost-saving, be also the important measures improving cane planting economic benefit; Two is that utilization rate of nitrogen fertilizer is lower.Major cause is that China sugarcane is mostly used carbon ammonium, urea or contains urea and ammonia-state nitrogen composite fertilizer, because sugarcane production rainwater in mid-term is more, direct volatilization loss or transfer rapidly ammonia-state nitrogen volatilization loss to after these conventional nitrogen applications, or be converted into nitric nitrogen and leaching goes out Among the Sugarcane root and loses, thus conventional fertilizer effectiveness is short, and utilization rate of fertilizer is low; Three is that to use chloride fertilizer more.Due to former sugarcane low price, in order to save cost, what generally use in Fertilizer application is cheap Repone K, use Repone K year after year and not only make soil compaction, and reduce sugarcane yield and sugar degree, experimental study also proves, uses potassium sulfate and can significantly improve Sugar Content in Sugarcane than Repone K.In recent years, along with sugarcane price rises, potassium sulfate benefit is used higher than using Repone K; Four is that Sugarcane N P and K is uneven.Major embodiment is that nitrogen is too much, and potassium is very few.Sugarcane is the kind of plant needing potassium higher, and potassium deficiency not only reduces sugarcane yield, and affects Sugar Content in Sugarcane.
In fertilizer, active phosphorus is easily by soil fixing in soil, and phosphate fertilizer should be concentrated and use, and in fertilizer, phosphorus potassium nutrition element all can not volatilize and leaching and losing, and the phosphorus potassium nutrition element adsorbed in soil and the fixing phosphorus potassium nutrition element of part can utilizations absorbed by crops.Nitrogenous fertilizer then can be converted into ammonia and volatilization loss and ammonia and be converted into nitric nitrogen and leaching loss, thus will solve the too much problem of Term Fertilization number of times, mainly control nitrogenous fertilizer release rate, allow nitrogen at the interim slow releasing of sugarcane production.Current control nitrogenous fertilizer release rate method has coating, generates the urea formaldehyde of long molecular chain with formaldehyde reaction, adds urease inhibitor and nitrification inhibitor.Wherein add urease inhibitor and nitrification inhibitor nitrogenous fertilizer price the most cheap, production technique is also relatively simple, but suppress urea decomposition and ammonia nitrification effect also better.With the addition of urease inhibitor at present and nitrification inhibitor composite fertilizer has been used on the crops such as wheat, corn, soybean, paddy rice, but the special compound fertilizer for sugar-cane that with the addition of urease inhibitor and nitrification inhibitor have not been reported.
Nitrogenous source kind has material impact for fertilizer effectiveness, utilization rate of nitrogen fertilizer and fertilizer cost, and generally, acyl ammoniacal nitrogen fertilizer fertilizer efficiency is slightly slow, and nitric nitrogen is the most easily for sugarcane absorbs, fertilizer efficiency is the fastest, but price is high, fertilizer efficiency is short, and ammonia-state nitrogen fertilizer efficiency speed is between acyl ammonia-state nitrogen and nitric nitrogen.Thus on nitrogenous source is selected, select acyl ammonia-state nitrogen and ammonia-state nitrogen not only can reduce fertilizer cost as mixed nitrogen, can also accomplish long-actingly to combine with fugitive, improve utilization rate of fertilizer, meet sugarcane production and grow needs.
Existing large quantity research on sugarcane nitrogen phosphoris and potassium fertilizer ratio at present, most research results shows, Sugarcane nitrogen phosphoris and potassium fertilizer ratio (N: P
2o

2o) be advisable with 1: 0.3-0.6: 0.6-0.9, we also show in research, in sugarcane district of China, are applicable to Sugarcane nitrogen phosphoris and potassium fertilizer ratio comparatively suitable with 1: 0.3-0.5: 0.6-0.8.
Thus go wrong in China's sugarcane fertilizer; propose one and can reduce fertilizer application frequency; improve utilization rate of fertilizer; soil protection; meet again China's sugarcane district soil supplying nutrient capability and sugarcane to the fertilizer formula of nutrient demand; just become and improve China's sugarcane yield and sugar degree effective way, simultaneously also significant for raising China cane planting economic benefit.
