The Comparison Test Of Mulberry Variety And Study About Corresponding Cultivation Techniques Of Husang-32 In Ningxia Irrigated Area

It is close that relation between good and bad of Mulberry varieties yield and quality of Mulberry leave.then proceed to affect economic benefit of sericulture production.ln recent years,as change to management way of improved varietization,standardization,intensiveization,specialization,scalization of sericulture production in Ningxia Irrigated Area.screening good varieties and summarize corresponding cultivation techniques of Mulberry variety is a important study task.At present.cultivated variety in Ningxia Irrigated Area is Husang-32 .which is extended in the 1980s,cultivation management is very extensive.cultivation standard isn't uniform.difference of management and technique is very big only they think present benefit.In order to carry forward elaboration of sericulture economic benefit and sericulture Industrialization in Ningxia Irrigated Area,according to demand of sericulture production.we have selected good varieties that are tested comparisonly by common cultivated technique management from Shanxi,Shandong,Hebei,Jiangsu, and Zhejiang so that varieties which suit Ningxia Irrigated Area will be sieved.then apply in production.At the same time.corresponding cultivation techniques of Husang-32 will be studied.too so that it is spreaded.Therefore this study has put 7 high yield high quality .stronger resistance good Mulberry varieties , and summarized a series of corresponding cultivation techniques of Husang-32 by experiment,measurement,investigation in Mulberry field and analysis and study experiment result are as follow:1.Through comparison of comprehensive characteristic.analysis and appraise,Xuan-792,Husang-32, Husang-197,Shan-305,Poluo,Huangsang-14,Shendong-l suit cultivation term in Ningxia Irrigated Area,we should extensive organizely2.Autumn planting Mulberry is sprout earlier.grow faster.leaf weight of 666. 7m Mulberry higher than spring planting Mulberry.But difference of leaf weight of 666.7m²Mulberry betweet Autumn planting Mulberry and Spring planting Mulberry isn't quite clear.So there should extend Spring planting in Ningxia Irrigated Area.3.Leaf weight of 666. 7m² Mulberry through experiment result,which take 1200 Mulberry trees each 666. 7m² and low trunk form.is higher than other cultivated pattern.So we should extend this low trunk cultivated pattern.4.0ne-way planting Mulberry tree in number and length of Mulberry branch each Mulberry tree.leaf weight of 666. 7m" is higher than width.So we should extend one-way planting Mulberry tree in countryside of Ningxia Irrigated Area except using mechanize.such as.company.farm and so on.5.There don't suit Summer cut of Mulberry branch in Ningxia Irrigated Area. We should make Spring cut and Chuqian cut.Yield of Mulberry field leave is higher than Spring cut to Lun cut and Chuqian cut.but techniques of Lun cut and Chuqian cut is difficult6. 666. 7m² MuIberry each year in Ningxia Irrigated Area apply 17.4-26.6kg pure N fertileizer to soil but pure N each 666. 7m² Mulberry tree per annum cann't top 26.6kg,or the branch of Mulberryexcessive growth, and it will effect leave yield of mulberry. At the same time,666. 7m²Mulberry each year in Ningxia Irrigated Area apply to 17.4-19.7kg prue N and 9.2kg pure P₂O₅ is the best.7. P fertilizer effects growth of Mulberry branch.The experiment prove.the more increase P fertileizer, the more strong of Mulberry branch.Draw water degree of the Mulberry branch decrease gradually.8. Intercroping watermelon contribute to Mulberry growing,then,intercropping soya beans and non-intercroping.About intercropping alfalfa,in accordan with specific conditions.Mulberry cann't intercrop maize and wheat resolutely.Meanwhile,we have made a deepgoing approach and analysis to selective area to introduced Mulberry varieties.and relation between selective Mulberry varieties and evaluated index,pattern of cutting Mulberry branch and labour production efficiency.apply fertilizer and Mulberry leave yield,Mulberry cultivated density and pattern of Mulberry.raising silkworm experiment and Mulberry leave quality.specific...
