Abstract
The invention relates to a special low-concentration slow release fertilizer for sugar cane. The nitrogen/phosphorus/potassium in the slow release fertilizer is 15:8:5. The invention can effectively the emergence rate, tillering rate and plant height of the sugar cane, and the test indicates that the emergence rate is enhanced by 0.9-1.7%, the tillering rate is enhanced by 2.3-4.2%, and the plant height is enhanced by 2.0-3.3cm; the slow release fertilizer can obviously enhance the agricultural yield of the sugar cane, and the test indicates that the unit yield of the sugar cane is enhanced by 0.8-1.5 t.hm<2>; the slow release fertilizer can obviously improve the quality of the sugar cane, and the test indicates that the field brix of the sugar cane is enhanced by 0.3-0.6% and the sucrose content is enhanced by 0.3-0.5%; and the invention reduces the number of times of fertilizer application, and lowers the labor cost. The special low-concentration slow release fertilizer for sugar cane is suitable to be applied to soil with medium sugar cane region fertilizers in tropical and subtropical zones in Southern China.
Description
Technical field:
The present invention relates to agricultural fertilizer, relate to specifically the special-purpose lower concentration slow release fertilizer of a kind of sugarcane.
Background technology
The features such as sugarcane is the important sugar crop of China, has growth cycle long, and turnout is high, and nutrient demand amount is large.Generally need to use base manure the whole production phase sugarcane, attack seed manure, attack evil fertilizer, attack the fertile and strong tail fertilizer of stem, could meet the needed nutrient of sugarcane production.In modern sugarcane agricultural, artificially applying fertilizer has become the most important measure of sugarcane production and high yield and high sugar cultivation.Yet the labour intensity that repeatedly applies fertilizer is large, time-consuming taking a lot of work, has been not suitable with the needs that modern Sugarcane Industry develops.Slow-release fertilizer has become the direction of countries in the world fertilizer industry Sustainable development.
Summary of the invention
The object of this invention is to provide the special-purpose lower concentration of a kind of sugarcane for the required various nutrients of sugarcane production fertile, adopt lower concentration slow-release fertilizer formula, the fertile bag of application fertilizer technology, make slow-release fertilizer there is higher effective nutriment in a fertilizer and lower cost, and do not use inorganic polymer etc. to be difficult for soil degrading material, non-environmental-pollution is the emphasis direction of sugarcane slow-release fertilizer future development.
The present invention is achieved through the following technical solutions its goal of the invention:
The special-purpose lower concentration slow-release fertilizer of sugarcane, slow-release fertilizer is by urea, monoammonium phosphate, fused(calcium magnesium)phosphate, Repone K and stopping composition are mixed, the mass ratio of nitrogenous, phosphorus, potassium be nitrogen: phosphorus: potassium=15:8:5; In slow-release fertilizer, each raw material by quality proportioning is:
Containing P
2o
5amount 49% and containing the monoammonium phosphate 1-85 of N amount 9%;
Containing P
2o
5the fused(calcium magnesium)phosphate 220-445 of amount 18%;
Urea 300-330 containing N amount 46%;
Containing K
2the Repone K 80-85 of O amount 60%;
Stopping composition 140-305.
Described stopping composition is that clay and filter mud mix by the mass ratio of 3:7.
This sugarcane lower concentration slow-release fertilizer that the present invention proposes, can make base manure and when cane planting, do that base fertilizer is disposable to be applied, and also can topdress sugarcane disposable applying in tillering phase, carries out cultivation and banking after using.
The present invention compared with prior art has following remarkable advantage: (1) can effectively improve sugarcane seedling rate, tillering capacity and plant height, and test shows to improve sugarcane seedling rate 0.9%-1.7%, tillering capacity 2.3%-4.2%, plant height 2.0-3.3cm; (2) can significantly improve the farm output of sugarcane, test shows to improve the per unit area yield 0.8-1.5thm of sugarcane
2; (3) can obviously improve the quality of sugarcane, test shows to improve degree of hammer into shape 0.3%-0.6% between sugarcane field, Sucrose 0.3%-0.5%; (4) reduce fertilizer application frequency, reduce labor cost.Be adapted at using on the medium soil of the semi-tropical sugarcane of South China Tropical district fertilizer.
Embodiment
Test explanation:
Test is established 2 and is processed 1 contrast:
Processing 1 is sugarcane lower concentration slow-release fertilizer, and nitrogen, phosphorus, potassium content are 15:8:5.During cane planting by the slow-release fertilizer of 15:8:5 according to 40 kg/ even applying in cane planting ditch per mu, when sugarcane enters the grand phase of growth in conjunction with cultivation and banking, the urea of N content 46% is imposed near sugarcane root system according to 40 kg/ mus, sugarcane is earthed up simultaneously, guarantee that fertilizer is covered by soil.
Processing 2 is sugarcane lower concentration slow-release fertilizer, and nitrogen, phosphorus, potassium content are 15:8:5.During cane planting by the slow-release fertilizer of 15:8:5 according to 60 kg/ even applying in cane planting ditch per mu, when sugarcane enters the grand phase of growth, in conjunction with cultivation and banking, do not topdress.
While contrast 1(CK1) being 10:10:5. cane planting for local market sale Nitrogen, Phosphorus and Potassium nitrogen, phosphorus, potassium content by the composite fertilizer of 10:10:5 according to 40 kg/ even applying in cane planting ditch per mu, when sugarcane enters the grand phase of growth in conjunction with cultivation and banking, the urea of N content 46% is imposed near sugarcane root system according to 40 kg/ mus, sugarcane is earthed up simultaneously, guarantee that fertilizer is covered by soil.
Plot experiment is 6 row districts, line-spacing 0.8 m, and long 10 m of row, community area 48 m2, repeat completely random district group test design for 3 times.Test is planted and topdresses, earths up unified time, and other field management measures are consistent.
The pilot survey sugarcane situation of emerging, tiller, enters elongating stage and measures sugarcane plant height, measures degree of hammer into shape between sugarcane field; The mensuration of sugarcane Sucrose adopts a polarimetry, and sugarcane juice pol, sugarcane pol, fiber divide, simple purity testing is with reference to < < cane sugar manufacture routine analysis method > >; Harvesting sugarcane Qi Duige community sugarcane carries out reality and produces mensuration.
Analysis of experiments result shows: with contrast 1 and compare, process 1 and to process 2 lower concentration slow-release fertilizer nitrogen used, phosphorus, potassium content be 15:8:5 fertilizer, on the number of emerging of sugarcane, all have impact significantly with seedling rate, but process 1 with processing 2 between not remarkable.Process 1 seedling rate and process CK1 raising 1.3%; Tillering capacity improves 4% compared with CK1; Sugarcane plant height elongating stage increases 2.4 m compared with CK1.Use lower concentration slow-release fertilizer nitrogen, phosphorus, potassium content is 15:8:5 fertilizer simultaneously, and ripening stage sugarcane yield and sugarcane quality are had to obvious facilitation effect.The sugarcane per unit area yield of processing 1 lower concentration slow-release fertilizer 15:8:5 used improves 0.9 t compared with CK1 output, between sugarcane field, degree of hammer into shape improves 0.4% compared with CK1, Sucrose improves 0.4% compared with CK1 output, the qualities such as sugarcane purity all have larger improvement, add up by analysis, process 1 and compare with processing 2, both difference aspect yield and quality is not remarkable.
By following examples, the present invention is further elaborated, but content of the present invention is not limited to described scope.
