Abstract
The invention relates to a hybrid rice planting method. Operating steps comprise: selecting seeds; determining seeding time and seeding quantity; fertilizing after the seeding; fertilizing first season rice at initial tillering stage; fertilizing the first season rice at initial booting stage; 20 days before first season rice harvest, performing fertilizing, weeding, water slurry management, pest and disease prevention and control, and other operations; performing fertilizing 10 days before the first season rice harvest; stopping water supply 5 days before the first season rice harvest; harvesting the first season rice; performing fertilizing about 5 days after the first season rice harvest, and adopting an irrigation way before ratoon rice heading and flowering, wherein the irrigation way is characterized by alternating wetting and drying, and mainly focusing on wetting; from the grain-filling period to the mature period, alternating drying and wetting, and mainly focusing on drying; and 7 days before harvesting, stopping water supply and performing the pest and disease prevention and control. The method is simple and easy to operate; because large temperature difference exists and no pesticide or little pesticide is used in growth period of ratoon rice, the produced rice is excellent in quality, excellent in taste, and the food safety is ensured; and furthermore, according to the planting method, a single season rice area is transformed into double cropping rice, thereby greatly increasing the unit area yield of hybrid rice and the production benefits of farmers.
Description
Technical field
The present invention relates to a kind of hybrid rice implantation methods.
Background technology
Improve paddy rice yield per unit area and be still one of key subjects of mankind nowadays needs solution, and current technology is only for the cultivation to improved seeds, it comprises sterile line of hybridized rice and maintainer reaches high yield with the raising of improved seeds and by seeding technique means respectively, the gene technology research of paddy rice is still taken at the primary stage, and (hybrid rice refers to and selects two in heredity, have different, the rice varieties that their merit again can be complementary simultaneously, hybridize, production has heterotic first generation crossbreed, for the production of).
The yield per unit area of existing hybrid rice is low.In addition, existing hybrid rice normally sows seedling in the first tenday period of a month in late April to May, becomes rice shoot through the time of about 1 month, to late May to early June by rice shoot rice transplanting in rice field, grow in 10 months, the first tenday period of a month be ripe.Such growing period, causes hybrid rice one to be only and can plant a season, limits the plantation frequency of hybrid rice.
Summary of the invention
For the deficiencies in the prior art, the present invention aims to provide a kind of hybrid rice implantation methods.
For solving the problem, the invention provides following technical scheme:
A kind of hybrid rice implantation methods, step is as follows:
Step a, seed selection, the seed of selection is " accurate two excellent 608 " Hybrid Rice Varieties that regeneration capacity is strong, anti-adversity good, output is high, rice is of fine quality;
Step b, determines to broadcast cultivation phase and seeding quantity: the suitable sowing time at the plantation family of seedling raising and transplanting is annual 25 ~ March 30 March, and seeding quantity is advisable with 1.5 kilograms, every mu of field, length of time rice seedlings grow 30-35 days; The Suitable Sowing Period at the plantation family of transplanting is annual 30 ~ April 2 March, and seeding quantity is advisable with 2 kilograms of sowings 25 ~ 28 dish transplanting one mu of field, about the 20 days length of time rice seedlings grow; The Suitable Sowing Period at direct-seeding planting family is annual 5 ~ April 8 April, seeding quantity every mu 2 kilograms;
Step c, after sowing, for accelerating Root Growth of Rice, promoting to tiller, strengthen paddy rice anti contravariance ability, direct-seeding planting family is spread fertilizer over the fields after 1 kilogram of efficient medium trace element slow-release fertilizer and appropriate composite fertilizer should be selected to mix thoroughly; The plantation family of seedling raising and transplanting and the plantation family of transplanting are spread fertilizer over the fields after 1 kilogram of efficient medium trace element slow-release fertilizer and appropriate weed killer herbicide or tillering fertilizer should be selected to mix thoroughly;
Steps d, the first rice crop early tillering stage, for promoting paddy rice effective tiller and improving rate of tillering panicle, shortens paddy rice length of internode, strengthens lodging tolerance, adopt trace element fertilizer 20 milliliters/mu and high-efficiency foliage fertilizer 20 milliliters/mu evenly to spray rice leaf;
Step e, at the first rice crop booting initial stage, for ensureing that paddy rice grows to heading flowering normal growth from booting, alleviating the impact that unfavourable weather is pollinated on paddy rice, reducing the generation of empty flat grain and lopsided grain, adopting antioxidant 50 milliliters/mu evenly to spray rice leaf;
Step f, first 20 days of first rice crop results, for strengthening photosynthesis, improve filling speed and quality, reach the object of results in advance, adopt physiological regulating control agent 50 milliliters/mu evenly to spray rice leaf, the mode of traditionally field management simultaneously carries out the work such as weeding, water starch management, damage by disease and insect prevention and control, emphatically paddy rice is carried out to the prevention and control of banded sclerotial blight, ensure that ratoon rice sprouts.
Step g, first 10 days of first rice crop results, after ensureing first rice crop results, the timely fast-germination of regeneration bud, every mu of use 20 kilograms of urea are taken advantage of to wet and are evenly spread fertilizer over the fields;
Step h, first about 5 days of first rice crop results, after mechanical harvest, toothing rice stub can erect in time, reduces mud and infects rice stub, promotes that regeneration bud is sent out multiple soon, increases To yield of ratooning crop, needs to cut off the water supply to paddy rice in time, ensures that field is dry and comfortable;
Step I, results first rice crop, for ensureing the quality and quantity that regeneration bud is sprouted, guarantees during results that paddy rice stubble height reaches 35 centimeters;
Step j, latter about 5 days of first rice crop results, every mu of use 5 ~ 10 kilograms of urea sprout poor location to regeneration bud, balance fertilizing is carried out in leaf look lighter location, ensure ratoon rice growth evenly;
Step k, adopt " horse race water " mode of filling before ratoon rice heading flowering, alternation of wetting and drying, to wet; Be grouted into ripe alternation of wetting and drying, based on dry, gather in the crops and cut off the water supply for first 7 days; Concrete condition is there is and prevents and treats in time in the extermination of disease and insect pest according to local plant protection departmental intelligence and field.
Beneficial effect: the present invention is not only simple to operation, and due to the ratoon rice growing period temperature difference greatly, not medication or few medication, so the rice of output is of fine quality, food flavor is fabulous, ensure that the safety of grain; In addition, this implantation methods makes single cropping rice district become double cropping rice, greatly improves the yield per unit area of hybrid rice and the productivity effect at plantation family.
