Intercropping plant technology in view of also not having at present a kind of paddy rice and Chinese sorghum the invention provides a kind of paddy rice and Chinese sorghum intercropping plant method, can improve grain yield greatly.
The technical scheme that the present invention solves its technical problem is: a kind of paddy rice and Chinese sorghum intercropping plant method, in same paddy field, except winter and early spring, carry out two boiled water rice intercropping two season of spring and autumn of morning and evening Chinese sorghum, perhaps ripe single cropping rice intercropping two season of a spring and autumn Chinese sorghum;
In the winter time or early spring, as Chinese sorghum plantation row, the ridge is high 30 centimetres～40 centimetres along the parallel ridging of plantation row of paddy rice, trapezoidal cross-section; The width of paddy rice plantation row is 2: 1 or 3: 1 with the width ratio of Chinese sorghum plantation row;
Chinese sorghum sowed at the beginning of 4 months or transplanted on the ridge spring, early sent out with plastic mulching is short, and the spring planting density of Chinese sorghum is 4.5 strains/m
2～6.5 strains/m
2, gather in the crops mid-July; Chinese sorghum late July in autumn is utilized Chinese sorghum regeneration, late October maturation, the autumn Chinese sorghum planting density with the spring Chinese sorghum planting density identical;
Sooner or later two boiled water rice intercropping two seasons of spring and autumn are during Chinese sorghum: early rice by the end of April～rice transplanting at the beginning of 5 months, late July results; Late rice is in rice transplanting in the last ten-days period in July, and gather in the last ten-days period in October,
During one ripe single cropping rice intercropping two season of spring and autumn Chinese sorghum: the single cropping late rice is live or insert mid-June kind at the beginning of late May～6 month.
Concrete, early, late rice can select river in Zhejiang Province Xian 15, peaceful 88 kinds respectively for use, the single cropping rice selects peaceful 81 or excellent 12 kinds in river in Zhejiang Province for use; Chinese sorghum can be selected Red Star for use No. 1.
Paddy rice is poured water based on moistening irrigation, and this is identical with the irrigation technique of paddy rice in the prior art, does not repeat them here.Planting patterns is identical separately separately with paddy rice, Chinese sorghum for the field Routine Management, also repeats no more at this.
Beneficial effect of the present invention is: make paddy rice, the alternate ribbon plantation of Chinese sorghum, break through water, Dry crop simultaneously in the forbidden zone of paddy field plantation, take full advantage of paddy field light, temperature, the time null resource and farming object height, short intercropping vertical cultivation limit row advantage, be a kind of height intensive, improve the new cropping system of cereal crops output significantly.Generally speaking, producing more food about 18～44%, is the highest a kind of planting type and the technology of current increases in grain production amplitude.Concrete economic results in society are as follows:
(1). water consumption is low.The main cause that the intercropping culture water consumption is low is that Chinese sorghum is planted in " dry farming band ", irrigates plane and evaporation discharge and reduces.
(2). the output height.Paddy rice, Chinese sorghum intercropping culture, water, drought have alternately been improved the permeability of paddy soil, redox potential raises, be conducive to growth and the growth of rice root, also good moisture, soil, illumination, space have been created for the growth of Chinese sorghum, both have all obtained good limit row superiority condition, and temperature, light, water, soil, space-time are fully used.Result of the test shows, purely do 490 kilograms in per mu yield early rice, 520 kilograms of late rices, add up to 1010 kilograms, be under 2: 1 the intercropping situation at the width ratio of the width of paddy rice plantation row and Chinese sorghum plantation row, 390 kilograms in per mu yield early rice, 415 kilograms of late rices, spring 190 kilograms of Chinese sorghums, autumn 205 kilograms of Chinese sorghums, add up to 1200 kilograms, 190 kilograms of mu volume increase, rate of growth 18.8%.Purely do 625 kilograms of per mu yield single cropping late rices, 505 kilograms of intercropping per mu yield single cropping late rices, spring 190 kilograms of Chinese sorghums, autumn 205 kilograms of Chinese sorghums, add up to 900 kilograms, rate of growth 44.0%.
(3). economic benefit: early, 2932 yuan of the pure work of late rice mu incomes, and 3364 yuan of intercropping, mu increases 432 yuan; 1875 yuan of the pure work incomes of single cropping late rice, 2542 yuan of intercropping, mu increases 667 yuan.
(4) embodiment
Below in conjunction with embodiment the present invention is described in further detail.
