Abstract
The invention discloses a combo fertilizer applicable to paddy rice in upper Yangtze River and a fertilizing method thereof. The combo fertilizer is prepared from a base fertilizer, a tillering fertilizer, a jointing fertilizer and an ear-grain fertilizer. The base fertilizer is prepared from the following effective components in weight percentage: 16 to 20 percent of nitrogen, 13 to 17 percent of phosphorus pentoxide, and 6 to 8 percent of potassium oxide; the tillering fertilizer is prepared from the following effective components in weight percentage: 26 to 30 percent of nitrogen and 20 to 24 percent of phosphorus pentoxide; the jointing fertilizer is prepared from the following effective components in weight percentage: 13 to 16 percent of nitrogen and 32 to 36 percent of potassium oxide; the ear-grain fertilizer has the same effective components as the jointing fertilizer. The paddy rice combo fertilizer can satisfy the nutrient requirements of the paddy rice in different periods, is matched to a soil nutrient supply rule, and is beneficial to improve the paddy rice yield, improve the nutrient utilization rate and increase the profit; compared with farmer conventional fertilization, the yield per mu is increased by 46 to 101kg, the income per mu is increased to RMB 62 to 110, the utilization efficiency of a nitrogen fertilizer is improved by 28.1 to 35.0 percent, so that the combo fertilizer has higher actual application value.
Description
Technical field
The invention belongs to agriculture field, particularly to a kind of set meal fertilizer being applicable to Upper Yangtze River paddy rice and fertilizing method thereof.
Background technology
The Sichuan of Yangtze upriver areas, Chongqing, Guizhou, Yunnan Si Sheng (city), existing rice field area 4,670,000 hectares, and Monitoring of Paddy Rice Plant Area and per unit area yield all have downward trend in recent years, therefore, the rice yield and the nutrientuse efficiency that improve one's respective area have important strategic importance.Popularizing of the technology that applies fertilizers scientifically is the Upper Yangtze River rice district key that realizes high-yield and high-efficiency.But, due to peasant culture quality is low and planting scale little (rice field area occupancy volume is less than 334m per capita2) etc. the impact of factor to make Technique Popularizing popularize difficulty the biggest.There is the problem that nutrient supply is inconsistent with crop nutrition content demand rule in peasant household's fertilising, such as, shown by peasants participation result, major part peasant only executes twice fertilizer, and all in paddy growth early stage (transplanting in latter 15 days), the fertilizer needed for whole for paddy rice Growing season (Growing season of medium rice about about 150 days) has been executed, this often leads to Later growth and de-fertile phenomenon occurs.Additionally, this area peasant applies fertilizer there is inclined nitrogen fertilizer application, the situation that phosphorus potash fertilizer is under-supply, this does not mates with current soil nutrient status also pole.Thus, need the nutrient requirement characteristics according to paddy rice, soil nutrient supply situation and fertilizer efficiency reaction at present badly and develop paddy rice-dedicated fertilizer, and simplify fertilizer practice, being beneficial to peasant uses, and improves rice yield and the nutrientuse efficiency in Upper Yangtze River rice district.
Summary of the invention
It is an object of the invention to provide a kind of paddy rice set meal fertilizer being suitable for China's Yangtze upriver areas and fertilizing method thereof, nutrient needed for providing for paddy rice different times, for the applying fertilizers scientifically of Upper Yangtze River paddy rice, fertilizer utilization efficiency provides an effective solution route, 46-101 kilogram is increased production than peasant habit fertilising mu, mu increases income and reaches 62-110 unit, fertilizer utilization efficiency improves 28.1-35.0%, is of very high actual application value.
For achieving the above object, the technical scheme is that
A kind of set meal fertilizer being applicable to Upper Yangtze River paddy rice is made up of base fertilizer, tillering fertilizer, jointing fertilizer and fringe granulated fertilizer；
The active ingredient of described base fertilizer forms as follows by weight percentage: nitrogen 16-20%, phosphorus pentoxide 13-17%, potassium oxide 6-8%；The active ingredient of described tillering fertilizer forms as follows by weight percentage: nitrogen 26-30%, phosphorus pentoxide 20-24%；The active ingredient of described jointing fertilizer forms as follows by weight percentage: nitrogen 13-16%, potassium oxide 32-36%；The active ingredient of described fringe granulated fertilizer is identical with jointing fertilizer.
Further, the raw materials by weight meter composition of described base fertilizer is as follows: urea 27-38%, MAP 22-31%, granulated calcium magnesium phosphate fertilizer 28-30%, potassium chloride 12-13%, each weight percentages of components sum is 100%；The raw materials by weight meter composition of described tillering fertilizer is as follows: urea 48-52%, MAP 48-52%, each weight percentages of components sum is 100%；The raw materials by weight meter composition of described jointing fertilizer is as follows: urea 28-36%, potassium sulfate 64-72%, each weight percentages of components sum is 100%；The raw material composition of described fringe granulated fertilizer is identical with jointing fertilizer.
The fertilizing method of a kind of set meal fertilizer being applicable to Upper Yangtze River paddy rice is: every mu of dose is: within 1-2 days, use 25-30 kilogram of described base fertilizer before Yi Zaiing；Within after transplanting 7-10 days, use described tillering fertilizer 8-10 kilogram；Within after transplanting 45-50 days, use described jointing fertilizer 8-10 kilogram；After transplanting 65-75 days, after Flag Leaves in Rice is extracted out, use 8-10 kilogram of described fringe granulated fertilizer.
The beneficial effects of the present invention is:Paddy rice set meal fertilizer disclosed by the invention is the nutrient requirement characteristics according to China's Upper Yangtze River region paddy rice, Soil Nutrients in Paddy Field supply situation and fertilizer effect design, the nutrient demand of paddy rice different times can be met, coupling soil nutrient supply rule, improve rice yield, improve plant recovery of nutrient and additional income.Being shown by the field test of multiple spot, promote the early growth and quick tiller of tiller, increase effective tillering quantity, increase production 46-101 kilogram than peasant habit fertilising mu, mu increases income and reaches 62-110 unit, and fertilizer utilization efficiency improves 28.1-35.0%.The present invention is that the applying fertilizers scientifically of Upper Yangtze River paddy rice, fertilizer utilization efficiency improve, it is provided that an effective solution route, is of very high actual application value, and market application foreground is wide.
