Analysis Of Tabacco Straw Reusing In Fields Effect And Balance Fertilize Technology In Jiahe Town

According to the status of the tabacco-plating field ,this issuse focus on the analysis of improving the field quality and balance fertilize tecnology.1 .the straw coverage could help modify the tempreture of the field layer during all the living time ,which keep the field warm when cold and get rid of heat when it is getting hot.this tempreture modification effection is helpful for the field to keep and save espercially in hot season .the effcetion are better put 500kg per mu than put 300kg in mu. it is almost no differ when we comparing the way of straw coverage and burying with no straw Reusing in fields during Mission period.but the straw output are much rich when straw Reusing and all- Reusing better than half,half prior no Reusing during full-grow time,blooing time and mature tiem. the way of straw coverage and burying could rich the tabacoo output and out-value ,price and the portation of middle-to-high level tabacoo.comparing all the ways of straw Reusing,put 500kg per mu gain the best effects and the best add portation.2. organic fertilize is good for improve the quality of the tabacco. when utilize organic fertilize 125kg,tabacco-specizing fertilizer 50kgs, tabacco-specizing seedling-rising fertilizer 5kgs, potassium persulfate 20kgs per acre,they effection would be better than any other way of re-using.3.in the enviroment of the field of the Jiahe tabacco-planting,some fertilizer like boron, magnesium, molybdenum is helpful for the the booming and mature of the tabacoo.adding 0.5-1kg boron, 10-15kg magnesium per acre,and 0.5kg boron-molybdenum combine fertilizer after housing,the output of the tabacco could add 7-20 kgs ,3-7%in middle-high tabacco portation,0.1-0.3 yuan per kilogram in price.the effection is outstanding for the aspet of output-adding and quality-upgrade.4.During balance fertilize period,Jiahen not only should pay attention to keep balance use of nitrogen, phosphorous, potassium,but also should attach more attention to the balance of macroscopic element and micro element .as for the way of fertilizing,Jiahe should combine the way of belt-fertilize and cave-fertilize,that is we called double layer or 101 fertilize method. In double layer fertilize,basic fertilizer take up 70% of the total.at the start period of shaping compartment and bulge,first should dig hole between the compartment ,then combine the remining base fertilizer and fire-land gray ,animal shit, stack them together for 15 to 20 days ,finally put them into the hole diged.altanatively,we could combine fire-land gray ,animal shit and mix them well,then put into the hole before 7-10 day before plant begins,it would be much better experienced rain.so that avoid the tabacco young plant to be burned. 101 fertilize method,base fertilizer take up 70%,the portation would be 4:3:3.firstly,we combine the base fertilizer and fire-land gray ,animal shit,and mix them well ,then put them into the cave 5-7 days before plant starts. 15cm height hole should be digged both sides near center holes,after 30% base ferlizer used respectively,then fill the hole.step-fertilizer take up 30% of the all,to be finished by 3-4 times within 35-40 days after plant.the first time fast-effect nitrogen shoud be done after plant,and for the second ,and third time step-special fertilizer should be used ,then fertilize special step- fertilizer and sulfuric acid potassium.in the case of production Jiahe tabacoo,9.5-10.5 kgs per acre would be advised for the fertilizer amount standard5. "puli"microorganism field modifier helps the foil getting loose ,which is good for the nutrient reach to the root parts,so that could be absorbed easily by the babacco plant.in all, puli"microorganism field modifier is helpful for adding foil fertilizer,fasten root growing,upgrading tabacoo disaster-resist ability,and adding the output, improving the quality ,which would be advised widely.6.the tabacco output ,quality,price are greatly improved afterr using the "jin bisheng"series fertilizer. 3-years experience shows that when use 200kgs I patten, 400kgsII-patten, 600kgsIII-patten"jingnbisheng" fertilizer per arce ,we found that it is no any harm to the tabacco growing,output and the quality but upgrade the output price and high-quality tabacco portaion ,greatly.
