Abstract
The invention relates to a sugar cane seedling plant and sound seedling cultivation method, which is provided aiming at that the sugar cane hybrid seed is tiny, and has comparatively light thousand seed weight, less nutrient content and villus; when cultivating the seedling, the seed is susceptible to fungi and has low germination rate, the seedling is weak and susceptible to diseases, and so on. The goal of cultivating sugar cane seedling vigorous and healthy plants is realized through the implementation of eight technical steps of the improvement of seedbed matrix, the improvement of seedbed structure, the seed disinfection and sparse seeding, the control of temperature and preservation of humidity to promote germination, the control of temperature and preservation of humidity to promote growth, timely fertilizer application, shading and seedling training, defoliation and chemical control to promote robustness. The seedling plant cultivated by applying the method has flourishing root system, dark leaf color, and vigorous and healthy plants, and is easy to be transplanted in fields; and the field transplantation survival rate of the seedling plant under the same conditions is raised by 10 to 15 percentage points.
Description
Technical field:
The present invention relates to a kind of sugar-cane tree-seedling strong seedling cultivation method.
Background technology:
Sugarcane is the important sugar [yielding of China, Sugarcane Superior Variety to the contribution rate of sucrose industry more than 60%.The new variety of sugarcane that current China cultivates mainly utilizes between kind, the hybrid seed between hybrid screens, but the sugarcane hybrid seed is tiny, and it is few to include nutriment, can not must grow seedlings earlier directly at field sowing.And, brought difficulty for the cultivation of seedling because the sugarcane thousand grain weigth is light, villous, nutrient are few.Adopt the conventional seedbed system method often to cause seed easy infection mould, emergence rate low, cultivate that seedling is weak, susceptible is died of illness and died.
Summary of the invention:
The purpose of this invention is to provide a kind of sugar-cane tree-seedling strong seedling cultivation method, it can effectively solve in the present culturing sugarcane seedlings process, and hybrid seed easy infection mould, emergence rate are low, cultivates the problem that seedling is weak, susceptible is died of illness and died.
The present invention is achieved through the following technical solutions:
The present invention is according to the characteristics of sugarcane hybrid seed, in conjunction with crop seed sprout growth rule, at the sugarcane seed characteristics, the seedbed seedling-cultivating method breaks traditions, by the enforcement that improves medium of seedling bed, improves seedbed frame, short rudiment is preserved moisture in seed disinfection light seeding, temperature control, temperature control is preserved moisture growth promotion, short strong eight technical steps of experienced seedling, leaf-cutting and chemical control that apply fertilizer, shade in good time, realize cultivating the purpose of the healthy and strong plant of cane seedlings, major technique is as follows:
1. matrix treatments: matrix components is organic matter, the immature soil, general calcium, dried, the crushing that will be that the organic matter of main component is exposed to the sun earlier with the farmyard manure,, organic by volume: the immature soil=1:1 mixing, the cloth bag of packing into the aperture for after 0.5cm iron sieve sieves, carrying out temperature is 122 ℃ of steam high-voltage sterilizing 2h, kill soil bacteria and weed seed, dry then obtain in the middle of the material, by volume in the middle of the material: general calcium=5:1 mixing is as seedling medium, general calcium must sieve, and the sieve aperture is 0.2cm;
2. prepare in the seedbed: hard wood is done growth * wide * height be the wooden frame of 50cm * 40cm * 11cm, place on the high brandreth of ground 120cm, the preprepared matrix of packing into, standby as the seedbed, before the sowing that its water spray is extremely wet, the seedbed is arranged in the greenhouse with spraying sunshading facility;
3. seed disinfection light seeding: it is 5min in 0.2% mercuric chloride solution that the sugarcane seed is soaked in concentration, filtered through gauze, wrings out, and adds 500mL matrix and rubs scattered out.According to seed germination rate, be sowed in the wooden frame, light seeding is good, every frame has 280～350 seedlings, sowed seed after, thin cover matrix, spray permeable;
4. the temperature control short rudiment of preserving moisture: cover and add a cover film, heat and moisture preserving with wet gauze; At after planting preceding 2 days, the maintenance indoor temperature was at 28～36 ℃; After planting 3～4 days, for keeping soil moisture, should spray water 1 time, and spray 0.5% carbendazim at interval in 2 days and prevent that mould from taking place, till rudiment finishes in the morning;
5. the temperature control growth promotion of preserving moisture: when the seedling as 80% reaches 2～3 leaves, connect the thin film and only carry out coverage shading and preserve moisture, keep indoor temperature at 22～40 ℃ with gauze; For keeping soil moisture, should respectively spray water 1 time in morning and afternoon, and spray 0.5% carbendazim at interval in 2 days and prevent that mould from taking place, grow to 5～6 leaves up to seedling;
6. fertilising in good time: when treating that seedling grows to 6～7 leaves, can spray, satisfy the seedling nutritional need with 0.05% urea; Grow to 8～9 leaves to seedling, the minority seedling begins to tiller, and is that the composite fertilizer of 10:10:10 melts to liquid waters pouring with N:P:K, replenishes the required nutrient of seedling comprehensively;
7. experienced seedling shades: when treating that seedling grows to 7～8 leaves, wooden frame is shifted out the greenhouse, place under the vacant lot of building the sunshade net, carry out adaptive training, make seedling smoothly transit to outdoor natural environment;
8. leaf-cutting, chemical control are short strong: after seedling carried out the transition to natural environment, sunlight was abundant, the liquid manure abundance, and it is comparatively rapid grow, at this moment should note trimming blade, and spraying concentration is the multiple-effect short MET of 4mg/L, promotes the seedlings root growth, cultivation strong sprout.
The beneficial effect that the present invention has is as follows:
Sugar-cane tree-seedling strong seedling cultivation method provided by the invention row simple to operate, easy, cost are low, convenient management, can grow seedlings by mass.Use cane seedlings well developed root system, leaf color depth, robust plant that this technology cultivates, be easy to field-transplanting.Under equal conditions, the field transplanting survival rate can improve 10～15 percentage points.The seedling manufacturing enterprise that this technology is fit to cane breeding unit and specialty promotes the use of.
Embodiment:
Sugar-cane tree-seedling strong seedling cultivation technology provided by the invention, only need the seedling manufacturing enterprise of cane breeding unit and specialty to possess minimum facilities such as seedling cultivation greenhouse, jumbo autoclave and brandreth, and eight operating technology steps that provide in strict accordance with the foregoing invention content part are implemented, can cultivate the healthy and strong plant of sugarcane, transplant the land for growing field crops, be used to screen new variety of sugarcane.
