Technology Of Hybridization And Reserving Seeds And System Of Popularization And Support On No Shell Mellen Seeds

No shell melon seed is a rare variation form.Because there's no shell,easily processing and eating and with the functions of officinal health cure,it has been developed and utilized quickly both at home and abroad in recent years.Based on analyzed,including the necessary conditions of targets completing quality and quantity and all sorts of limiting factors.In the thesis,many aspects about the pattern,orgnization and administration setup."company+ school+base+farmer" have been demonstrated.1.There is unique geographical advantages to develop no shell melon hybridization in Jiuquan city.Reserving seeds is the supporting industry of Jiuquan city and local farmers have higher quality in reserving seeds.Wine spring nature the term is superior,and the calories is ample,dry and little rain,day and night the difference in temperature is heavy, and breed of include the farm crop seed of pumpkin at inside the grain full.the pure degree is high.and the color and luster is positive,and the deep and enjoyable door is welcome. Through popularization works of 2000-2002 years,The technology is very popular among farmers because its economic benefits exceed nearly 3 times of field crop.such as maize, wheat,etc.Its net income is 11750 yuan/hm~2 and it has better increase production potential. In short,enlargement and popularization of no shell melon seeds is feasible.2.There are several limiting factors on popularization technology of no shell melon seeds:Firstly,the fierce market competition and the increase of farm production price have led to a series of problems.For instance,it is difficult to be carried out.enhances the difficulty to farmer's organization and management and inceases the production cost. Secondly,powdery mildew is threatening the increase of reserving seeds output,the output dropping 6-25%and even higher when endangering seriously.Finally.the couvade of specific variety combination spent too much time and had a great effect on output. Meanwhile,the problem lies in specific base.which has become the hidden trouble of realizing reserving seed's goal.3.The producing and organizing pattern of no shell melon seed's popularization is as follows:"company+school+base+farmer".In this pattern,Wuwei Golden seed comply acts as locomotive,the scientific and technological school of agriculture and forestry in Jiuquan is its technological carrier,and farmer is seen as the basic production unit.These three sections combine production,learning with researching and shape a system of popularization and cooperation,involved in producing,supplying and selling as a whole. The interacting communication and responsibility among sections make sure the output and quality target of reserving seeds.The part-work and part-study department of technological school is in charge of the popularization plan.which is divided into 9 stages,including project implement,seeding,management of seedling stage,harvesting,buying,identifying and paying.4.The pattern attaches importance to organizational system and technological system from beginning to the end.The former is composed of the structure of organization and management,the base,the establishment of typical demonstration spot and the skillful training to farmers,etc.During the course of reserving seeds,inspecting is viewed as a significant way to evaluate whether the farmers' field management and technical manipulation have reached demand and technical criterion.As the basis of assessing seed quality ranking,the inspecting course including two sides:field inspecting and seed testing after harvest.5.In 2003.the result shows that the planning target has been basically realized and achieved remarkable economic benefits.Through this kind of technology,the actual popularization area has extended to 67.3 hm~2.71520.0 kg regular seeds have been gained whose average output is 1070kg/hm~2,production value is 2.268,000 yuan.the profit is 576,000 yuan,the reserving seeds' income gained by farmers is 1,430,000 yuan and net income is 1,016,000 yuan.Besides,the project implement has improved their culture accomplishment,adjusted agricultural structure,realized the employment of suplurs workforce in country and participated in agricultural industrialization management.6.Jiuquan agriculture and forestry scientific and technological school is the pioneer of agro-extension,which meets the impersonal demand of current agro-extension subject pluralistic serving and has realized the system innovation of agricultural extension.7.The result of 2003 indicates that Jiuquan is an ideal area to hybridization.It is feasible that school adopted the pattern:"company-school+base+farmer".As long as the technology of reserving seeds and managing measures are in place,high-yield and high-quality goal can be realized,can increase economic efficiency notably and reduce the production cost.
