Abstract
The invention discloses a mixed rice planting method capable of improving lodging resistance. The method is characterized by comprising the following six steps: seed selection, mixing, seedling raising, rice seedling transplanting, fertilizer application and harvesting. With the adoption of the method, the contradiction between high yield and lodging resistance of rice is effectively eliminated, the lodging resistance of the rice is improved while certain yield of rice is guaranteed, the yield of rice cannot be influenced by lodging, and the stability of the yield of rice is greatly improved.
Description
Technical field
The invention belongs to rice cultivating method technical field, be specifically related to a kind of Oryza sativa L. companion planting method improving lodging resistance.
Background technology
Oryza sativa L. originates in China, and before 7,000 years, Yangtze River in China basin is with regard to rice cultivation.According to different methods, Oryza sativa L. can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, Oryza sativa L. var. glutinosa Matsum. and non-Oryza sativa L. var. glutinosa Matsum..China scientist Yuan Longping is made that tremendous contribution to the research of hybrid rice, is described as " father of hybrid rice ".The Oryza sativa L. institute i.e. Oryza glutinosa of knot reality, Oryza glutinosa (grain) claims rice, scented rice, rice after shelling.Nearly half population in the world, all with rice for food.The eating method of rice is varied, has rice, congee, rice cake, rice cake, rice wine etc..Oryza sativa L. is in addition to edible, it is also possible to wine brewing, sugar industry raw material, and rice husk, rice straw can be as feedstuffs.China Oryza sativa L. main producing region is mainly the Northeast, the Yangtze river basin, Pearl River Delta.Belong to direct economy crop.The staple food of 1/3rd mankind the most in the world.Rice lodging refers to that the Oryza sativa L. of vertical growth occurs the most crooked because the natural cause such as hailstorm, heavy rain or external force affect, and even Herb is crawled and is poured on the phenomenon on ground.Lodging can make the yield of crop and quality reduce, results difficulty.When Oryza sativa L. seriously lodges, have a strong impact on yield, possibly even cause total crop failure.
In prior art, rice yield the most resistant to lodging is relatively low, and the lodging resistance in rice ability of a lot of high yields is relatively low, a contradiction is created between resistant to lodging and high yield, accordingly, it would be desirable on the premise of one can ensure that rice yield, improve the cultural method of lodging resistance in rice ability.
Summary of the invention
It is an object of the invention to provide a kind of Oryza sativa L. companion planting method improving lodging resistance, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of Oryza sativa L. companion planting method improving lodging resistance, specifically includes following steps:
S1, seed selection: choose the higher high-yield rice seed of a certain amount of yield and the strong rice paddy seed resistant to lodging of a certain amount of lodging tolerance；
S2, mixing: high-yield rice seed and rice paddy seed resistant to lodging are sufficiently mixed in certain proportion；
S3, nursery: mixed rice paddy seed was sowed in the rice seedling bed after whole ground with certain density in suitable season；
S4, rice transplanting: the rice shoot in rice seedling bed grows to certain height, be transplanted to rice shoot in rice field with certain density, and ensures that rice shoot layout is orderly；
S5, fertilising: during Rice Growing, base manure, fetilizer for tillering, ear manuer, granulated fertilizer are all with a certain proportion of nitrogen, phosphorus, potassium mixed fertilizer, prevent the nitrogenous fertilizer that applies too much and potash fertilizer is very few.
S6, harvesting: when spike of rice hangs down, golden yellow full time, it is possible to start harvest, utilize harvester, after spike of rice is involved in, directly spike of rice separated with rice stem, the spike of rice of just becomes Oryza glutinosa.
Preferably, the one-tenth after mixing between described high-yield rice seed and rice paddy seed resistant to lodging is grouped into high-yield rice seed 60-80 part, rice paddy seed 20-40 part resistant to lodging.
Preferably, described mixed rice paddy seed is sowed the density in rice seedling bed and is 90-110 gram every square metre.
Preferably, the height of described shoot transplanting equipment is 8-12 centimetre.
Preferably, described base manure, fetilizer for tillering, ear manuer, granulated fertilizer usage ratio are 5:5:1.5:0.5.
Preferably, in described nitrogen, phosphorus, potassium mixed fertilizer, ratio between N, P2O5 and K2O is 1:0.5:0.7.
The technique effect of the present invention and advantage: the Oryza sativa L. companion planting method of this raising lodging resistance, by to high-yield rice seed and rice paddy seed companion planting resistant to lodging, while can accomplishing to ensure certain high yield ability, it is effectively improved the lodging tolerance of Oryza sativa L., and owing to controlling the ratio between nitrogenous fertilizer and phosphate fertilizer, the lodging tolerance making Oryza sativa L. overall obtains a guarantee, therefore, the present invention effectively solve rice high yield and resistant to lodging between contradiction, while ensureing the certain yield of Oryza sativa L., improve its lodging tolerance, make it because of lodging, yield will not be impacted, substantially increase the stability of rice yield.
Accompanying drawing explanation
Fig. 1 is the method flow schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
The invention provides a kind of Oryza sativa L. companion planting method improving lodging resistance as shown in Figure 1, specifically include following steps:
S1, seed selection: choose the higher high-yield rice seed of a certain amount of yield and the strong rice paddy seed resistant to lodging of a certain amount of lodging tolerance；
S2, mixing: high-yield rice seed and rice paddy seed resistant to lodging are sufficiently mixed in certain proportion；
S3, nursery: mixed rice paddy seed was sowed in the rice seedling bed after whole ground with certain density in suitable season；
S4, rice transplanting: the rice shoot in rice seedling bed grows to certain height, be transplanted to rice shoot in rice field with certain density, and ensures that rice shoot layout is orderly；
S5, fertilising: during Rice Growing, base manure, fetilizer for tillering, ear manuer, granulated fertilizer are all with a certain proportion of nitrogen, phosphorus, potassium mixed fertilizer, prevent the nitrogenous fertilizer that applies too much and potash fertilizer is very few.
S6, harvesting: when spike of rice hangs down, golden yellow full time, it is possible to start harvest, utilize harvester, after spike of rice is involved in, directly spike of rice separated with rice stem, the spike of rice of just becomes Oryza glutinosa.
Further: between described high-yield rice seed and rice paddy seed resistant to lodging, the one-tenth after mixing is grouped into high-yield rice seed 60-80 part, rice paddy seed 20-40 part resistant to lodging.
Further: described mixed rice paddy seed is sowed the density in rice seedling bed and is 90-110 gram every square metre.
Further: the height of described shoot transplanting equipment is 8-12 centimetre.
