2o prepares).Adopt rich water quality management mode of the present invention etc. to substantially increase tillering ability and the Grain Filling power of long length of time rice seedlings grow machine transplanting of rice seedling, number of productive ear and fringe examples explain are significantly improved, effectively increases long length of time rice seedlings grow machine transplanting of rice rice output.
Description
Technical field
The present invention relates to a kind of cultivation method improving long length of time rice seedlings grow machine transplanting of rice rice output, belong to rice cultivating technique field.
Background technology
Transplanting rice shoot is different from conventional hand rice transplanting seedling, and because its thickness of sowing is large, therefore seedling age elasticity is little, and require high to the transplanting length of time rice seedlings grow, usually require that the length of time rice seedlings grow is within 25 days, seedling quality is high, and suitable property of inserting is good, turns green fast after rice transplanting.But in late inbred rice district, due to the impact of preceding crop harvest time and adverse weather factor, ubiquity surpasses length of time rice seedlings grow phenomenon.Usually defining the rice shoot of the length of time rice seedlings grow more than 30 days is long length of time rice seedlings grow rice shoot.After long length of time rice seedlings grow shoot transplanting equipment, not only turn green slow, and tillering ability weakens, growth retardation, finally causes number of productive ear to reduce, fringe head diminishes, and has had a strong impact on rice yield.
At present, in production, conventional machine transplanting of rice rice culture method is:
Seeding stage manages: adopt watery ricenursery, keeps seedling ditch inner aqueous layer and furrow face to maintain an equal level.In 1 leaf 1 heart stage, use " wean is fertile ", urea 10kg is executed in every mu of rice seedling bed; 4d before transplanting, executes urea 7kg as " send and transfer fertilizer " for every mu;
Field management: 3-4 seedling is inserted in every cave, and land for growing field crops nitrogen application ratio is base manure: tillering fertilizer: ear manuer=5:3:2, and nitrogenous fertilizer amounts to purity nitrogen by 180kg/ha() to use, nitrogen, phosphorus, Potassium Fertilizer ratio are 2:1:2.
Above-mentioned cultivation method is more suitable for the of the right age rice shoot of the length of time rice seedlings grow within 25 days, but cannot meet the requirement of long length of time rice seedlings grow machine transplanting of rice rice high yield in production.
Summary of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art, by research and experiment, a set of new cultivation method is proposed, improve tillering ability and the Grain Filling power of long length of time rice seedlings grow machine transplanting of rice seedling, number of productive ear and fringe examples explain are significantly improved, effectively increase long length of time rice seedlings grow machine transplanting of rice rice output.
Technical scheme of the present invention is: a kind of cultivation method improving long length of time rice seedlings grow machine transplanting of rice rice output, is characterized in that,
(1) bed soil management
Get vegetable garden in degree of depth 15cm or rice field topsoil as seedling soil; Before fetching earth, every 120m
2topsoil (degree of depth 15cm) 140-160g fenaminosulf 80-120 doubly dilutes rear direct sprinkling; Sieve after fetching earth, make fine earth particle diameter between 2 ~ 4mm; N P and K (15%-15%-15%) composite fertilizer 0.1-0.2kg is evenly admixed in every 100kg fine earth after sieving;
(2) seeding stage management
Place seedling soil in seedling dish, the dark 2-2.5cm of soil, then sowing in dish, the outdoor seedling dish (hard disk) that stacks erects bud, when seedling growth extremely highly reaches 0.4-0.6cm, then seedling dish is carried to rice seedling bed carries out balance;
(starting after the balance of rice seedling bed) is based on " horse race water " before 1 leaf 1 heart stage, pours water and does not have seedling dish, then drained by water, emptying, in time coiling interior bed soil and become dry, again goes up water and does not have seedling dish, drain, so repeatedly;
During 11 heart stage of leaf, in seedling dish, use N P and K (15%-15%-15%) composite fertilizer (composite fertilizer's consumption is the 0.08-0.12% of seedling soil property amount), upper water after fertilising; Later stage does not apply fertilizer, and is beneficial to improve seedling age elasticity; Water management adopts alternation of wetting and drying method, that is: upper flat ditch-water (upper water does not have seedling dish), and after consumption is done naturally, then fill with flat ditch-water, consumption is dry naturally, so repeatedly; To transplanting front 3-4 days, filling with half ditch-water (ditch depth 20cm) restraining the growth of seedlings, being beneficial to the machine transplanting of rice.
(3) field management
Adopt rice transplanter to carry out rice transplanting, 6-7 seedling rice shoot in long age is inserted in every cave, and land for growing field crops nitrogen application mass ratio is base manure: tillering fertilizer: ear manuer=2:4:4, and nitrogenous fertilizer amounts to purity nitrogen by 270-290kg/ha() use; Nitrogenous fertilizer, phosphate fertilizer (amount to P
2o
5), potassium executes and (amounts to K
2o) be 2:1:1 with mass ratio; Phosphate fertilizer is made base manure 1 property and is applied, and base manure made by potash fertilizer and ear manuer divides 2 equivalent to apply;
Tillering stage foliage-spray 80mg/L uniconazole P, every mu of amount of application 23-27kg, uses 1 time altogether; Panicle spike primordium differentiation stage applying liquid siliceous fertilizer (H in liquid silicon fertilizer
4siO
4content is>=70wt%) 5.5-6.5kg/ mu, be watered filling root; Foliage-spray silicon solution (uses Na
2siO
3.9H
2o prepares, and concentration is 2.5-2.8mmol/L), use 2-3 time altogether, every 6 days 1 time, foliage-spray total amount is every mu of 35-45kg;
The same conventional method of water management, is specially: water depth 1-2cm in land for growing field crops during transplanting, accomplishes not float seedling, does not fall seedling, not empty seedling; Tillering stage, shallow water duty filled with (depth of water maintains 2.8-3.2cm); Naturally cut off the water supply during enough seedlings dry dry field, light dry field splits osculum to Tanaka, repeatedly dry field (pour water after falling to doing 3-4cm); Booting stage and flowering pustulation period adopt Dry-wet alternate irrigation mode (pour water after falling to doing 3-4cm), stop pouring water to ripe first 1 week.
Described long length of time rice seedlings grow rice shoot is the rice shoot of the length of time rice seedlings grow more than 30 days.
Preferably, before described step (1) fetches earth, every 120m
2topsoil (degree of depth 15cm) directly sprays with after 150g fenaminosulf 100 times dilution.
Preferably, the uniconazole P of described step (3) foliage-spray in tillering stage 80mg/L, every mu of amount of application 25kg.
Preferably, described step (3) panicle spike primordium differentiation stage applying liquid siliceous fertilizer (H in liquid silicon fertilizer
4siO
4content is 80wt%) 6kg/ mu, be watered filling root.
Preferably, Na in described step (3) foliage silicon fertilizer
2siO
3.9H
2o concentration is 2.65mmol/L; Its foliage-spray total amount is every mu of 40kg.
The invention has the beneficial effects as follows: adopt rich water quality management mode of the present invention etc. to substantially increase tillering ability and the Grain Filling power of long length of time rice seedlings grow machine transplanting of rice seedling, number of productive ear and ripening rate are significantly improved, effectively increases long length of time rice seedlings grow machine transplanting of rice rice output.
