Abstract
An ultralow-density cultivation method for hybridized rape features that its planting density is greadly decreased to less than 500 plants per Mu without changing existing planting and manage ment modes. Its advantages are robust rape (5-9 cm for diameter and 2 m for height), and high yield of rapeseed (250 Kg/Mu).
Description
Technical field
The present invention relates to the cultivation method of a kind of crops, exactly is a kind of cultivation mothod for planting hybrid cole in ultra-low density.
Background technology
Rape is one of primary raw material of oil prodution industry, is all extensive economic crops of plantation of the whole world, and in China's southern area govern-house-variety of oil crop especially.
For improving the output of rape seed, pay close attention to the improvement of rape variety for many years mostly, and played positive effect, such as No. 2, cross-bred rape Qin of the current general popularizing planting of China oil, kinds such as No. 7, Qin oil, the per mu yield rape seed reaches 100 kilograms, has increased significantly than traditional kind.The plant hybrid vigour of cross-bred rape is strong, and its field plant density decreases than traditional category, however, no matter is live or seedling raising and transplanting at home and abroad, its planting density all more than every mu 20,000 strain, have in addition up to 30,000 strains.This domestic scholars was once advised reducing planting density, be reduced to about 10,000 strains of every mu of plant.
Summary of the invention
Rapeseed cultivation has live and transplants dual mode, the former comprise sowing and emerge after field management, as thinning, water, fertilizer, plant protection etc., the latter comprises sowing, grows seedlings, and transplants and field management.Technical problem to be solved by this invention is: use existing good Hybrid, under the prerequisite that does not change plantation and management mode, by reducing the method for planting density significantly, not only the per unit area yield of rape seed is greatly improved, and the overall economic efficiency of rapeseed cultivation also is significantly improved.
Planting density of the present invention is an every mu of rape plant number≤500 strains.This extremely-low density kind method for planting makes rape individual plant proterties reach the level of ultralimit, and collar is sturdy, 5～9 centimetres of diameters, and 2 meters of plant heights are up to 2.2 meters.Receive beyond thought high yield effect simultaneously, the rape seed per unit area yield reaches 250 kilograms/mu, is 2.5 times of present cross-bred rape average yield.In addition, plant needed other inputs, as the worker, the time, kind, fertilizer, medicine etc., become all that multiple is underground to fall, cost reduces significantly.Extremely-low density kind method for planting helps improving the cropping index in soil.Because plant spacing is low, when suitable adjustment spacing in the rows when adding wide row space, going up idly of line-spacing, utilize rape light leak in winter effect to interplant other crops, as, garlic, radish, the spring potato, spinach, coriander, April green grass or young crops, watermelon etc.Interplanting one side liquid manure is shared and has been improved economic benefit, helps the synergy that performance brings out the best in each other between crop on the other hand, such as, garlic can reduce the damage by disease and insect of rape, and the effect of blocking of rape makes the vegetables of interplanting more tender and crisp.Or the like.The overall economic efficiency of this method is 4 to 5 times of conventional method in a word.
Embodiment
With the transplanting is example, and the vegetable seed kind through sowing, is grown seedlings and transplanted to 13 true leaves, survives the back field management until results.
Every mu of several 500 strains of plant when 1, transplanting.
Every mu of several 250 strains of plant when 2, transplanting.
