Description
Technical field
It is special-purpose fertile to the invention belongs to cotton water body seedling bed floating grow seedling, is specifically related to material composition and ratio, compound method, purposes and the scope of application etc. in this special-purpose fertilizer.
Background technology
At present, the raising seedling of cotton mode has two kinds, a kind of is substrate seedling, as the Yang Tie of academy of agricultural sciences, Henan Province steel etc. (cotton industrial breeding technique and high-yield and high-efficiency technical regulation [J] thereof. the Henan agricultural sciences, 2003 (9): the 23-24) substrate seedling of Chuan Jianing, realized the surviving rate more than 95% and 5～7d seedling-slowing stage (also shortening to some extent) behind the cotton seedling non-soil replanting, realized that also cotton seedling still can reach the dreamboat of These parameters at indoor storage 3d than nutrition pot; Mao Shuchun (cotton " two do not have two change " cultivation technique research new development [J]. Chinese cotton, 2004,31 (9): 29) wait industrial seedling rearing in " two changes of two nothings " cultivation technique of setting up." two do not have two change " cultivation is meant Cultivation of Cotton Seedlings Without Soil, carrier free (single seedling) transplant and the grow seedlings general name of batch production and transplanting mechanization technology, adopt agronomy and agricultural machinery combination, the a whole set of configuration of technology, product, commodity, market are used and the having a extensive future of commodity industrialization.This mode is easy and simple to handle, and sprout term disease is light, is adapted to industrial seedling rearing, but because water supply in media and nutrient content are limit, needs repeatedly moisturizing to take a tonic or nourishing food to build up one's health between nursery stage and divide, and is suitable for the following little transplantation of seedlings of 2 leaves, 1 heart.Another kind is a feeding block seedlings raising, use on a large scale in south at present, but feeding block seedlings raising technology consumption worker is many, according to statistics, the annual recruitment in cotton field, the culturing and transplanting seedlings stage accounts for 50%, the field management stage in mid-term accounts for 25%, receive flower and sell flower and account for 25%, therefore, the recruitment of growing seedlings too much makes plants cotton industry labour productivity and is difficult to improve.The contradiction of culturing and transplanting seedlings stage and food crop summer harvesting and sowing is the most outstanding, strives season, and struggle for the work force between farming and nonfarming sectors (Han Shijie, Yuan Chunxin, Cui Shiyou etc. about the thinking [J] of raising seedling of cotton batch production and transplanting mechanization. cash crop, 2000 (4): 12-13).Feeding block seedlings raising also exist problems such as the low and easily dead seedling of seedling rate (Zhang Yunsheng. the some problems of cotton nutrition culturing and transplanting seedlings are just discussed [J]. crop magazine, 1996 (1): 13-15).Because the feeding block seedlings raising of present single household is difficult to the Artificial Control natural condition, runs into low temperature easily, seedling rate is low, in addition, nutrition pot soil disinfection difficulty, soil carries germ, cotton seedling easy outburst in early stage anthrax, damping-off, overworked disease and eqpidemic disease etc.Produce the artificial emasculation pollination hybrid cotton that goes up positive big area popularizing planting now, improved output of cotton greatly, but seed needs artificial hybridization, seed production cost height, the price of seed is also high, if the low and seedling death phenomenon of seedling rate is arranged, will increase seedling cost.Feeding block seedlings raising needs management of weeds because soil system nutrition pot is general more fertile, if control improper, cotton seedling easily becomes high pin seedling, and also there is the alms bowl that easily looses in feeding block seedlings raising, and transplanting survival rate is low, transplanting is taken a lot of work and is transplanted the back and delay problems such as seedling length, and influence is early sent out and output.Cotton planting is from the seed sowing of the sixties in 20th century, to feeding block seedlings raising, the membrane covering of the eighties, experience half a century, the scientific research personnel has paid hard sweat, but since these growing and cultivation method is time-consuming takes a lot of work, labour intensity is big, drops into higherly, is difficult to guarantee reasons such as cotton seedling once all sprouts, influence the development of China's Cotton Production and the raising (Chen Zhende of output always, yellow person of outstanding talent. the research [J] of several frequently seen seedling medium main characteristic. soil, 1997, (2): 107-108).Therefore we explore new method for culturing seedlings and change the status quo, and adopt water floatation seedling method of cotton, and this method has been applied for national inventing patent (the patent number of accepting: 200510031883.3).And the key of cotton water floatation seedling is the nutritional needs that will solve cotton in seedling stage, promptly will work out the special-purpose fertile of cotton water body floating seedlings.The Cotton Research Institute researchist of Agricultural University Of Hunan has carried out the special-purpose fertile correlative study work of cotton water floatation seedling in 2003～2005 years, and it is special-purpose fertile successfully to develop the cotton water floatation seedling.
Summary of the invention
Technical problem to be solved by this invention is the needs to trace elements such as nitrogen, phosphorus, potassium macroelement and copper, zinc, iron, manganese, boron in cotton water floatation seedling seedling stage, solves the easy hypertrophy of cotton in seedling stage and the phenomenon of disease occurs.1.. this dedicated fertilizer is mixed with grow seedling nutritional liquid and carries out floating seedlings, can avoid repeatedly supplying water in the matrix rice seedling on upland field process and the loaded down with trivial details work of the liquid that supplements the nutrients, and bring pathogenic bacteria to the seedbed easily during the moisturizing of matrix rice seedling on upland field, and cotton seedling is fallen ill; 2.. the cotton in seedling stage over-ground part stem, the leaf growth-inhibiting substance that contain in this special-purpose fertilizer can prevent cotton excessive growth; The promotion material that contains can promote growth, makes seeding quality good, looks healthy and strong; 3.. the metal-salt that contains in this special-purpose fertilizer, can fertile medicine dual-purpose, the control disease in cotton seedling stage there is tangible effect; 4.. this special-purpose fertilizer can guarantee that cotton seedling individuality all can absorb the nutritive medium of same concentrations after being dissolved in water body, so cotton seedling growing way neat and consistent, and this is that matrix rice seedling on upland field and feeding block seedlings raising are not accomplished; 5.. the fertile water-soluble formation grow seedling nutritional liquid of this special use, after residual nutritive medium can being added water after the end of growing seedlings, be used to water cotton seedling, make peace root and stem of certain plants water or a water of living.At present in the feeding block seedlings raising chemical fertilizer excessive to use phenomenon serious, average utilization has only 35%, has not only caused the significant wastage of the energy, has also brought all drawbacks such as environmental pollution, the hardening soil simultaneously.The contrast traditional method, this special-purpose fertile by using, can increase substantially utilization rate of fertilizer, reduce environmental pollution etc.
