Abstract
The present invention discloses a diversity corn and potato planting method capable of controlling corn diseases. Severe and mild corn blight can be effectively controlled. The present invention has the technical scheme that corn and potatoes are simultaneously cultured in the same field, the corn and the potatoes are intercropped in different rows, the corn is planted for 2 to 4 rows, and the potatoes are intercropped for 2 to 4 rows; the row spacing of the corn and the potatoes is from 30cm to 60cm, the potatoes are sown 20 to 35 days earlier than the corn, and corn varieties are all varieties whose height exceeds 1.5m.
Description
Technical field
The present invention relates to a kind of method of controlling maize diseases, its technical field belongs to the plant protection subject.
Background technology
In the time-honored agricultural production of China, the working people just has kind miscegenation and crop miscegenation in practice to reach better protection effect, obtains the experience of more voluminous amount.For example, corn and soybean miscegenation, corn and peanut miscegenation obtain the volume increase of grain; The part rural area on ground such as Sichuan, Chongqing, Yunnan, planting between peasant household knows corn and potato mixes can diseases prevention.For a long time, the phenomenon of these bio-diversity control damage by disease and insect does not obtain deep system research, does not have best cropping pattern yet, does not more disclose its inherent mechanism, thereby is not generally applied on producing as yet.
Summary of the invention
Main purpose of the present invention is the deficiency that overcomes existing method, and a kind of method that can effectively control corn northern leaf blight and southern leaf blight is provided, so that corn, potato raw production capacity enough high yield, high-quality, shape up efficiently.
This method is the planting type that keeps corn and potato in the piece of same field, between corn and the corn, the spacing in the rows between potato and the potato, line-spacing and density is cultivation method routinely all, and corn carries out intercropping with potato by the different rows ratio, corn planting 2-4 is capable, intercropping potato 2～4 row.Line-spacing between corn and the potato is 30-60cm, and potato is sowed 20-35 days in advance than corn, and corn variety is that plant height surpasses all kinds of 1.5 meters.
This method energy Sustainable Control corn northern leaf blight and southern leaf blight can alleviate disease hazard, reduces environmental pollution, improve quality, increasing both production and income.The main factor of corn/potato miscegenation control corn northern leaf blight and southern leaf blight is by two kinds of crop plant discrepancy in elevation, has formed three-dimensional plant group, has changed farmland microenvironment weather conditions, is unfavorable for that the generation of disease is popular; The result shows that the companion planting field is more later than planting field disease generation only, and generation speed is slower.Simultaneously, preserve and rationally use the variety of crops resource recovering, exploring sustainable agriculture will be of great practical significance.The application of this method has strengthened the stability of field ecosystem, has improved the anti-disaster ability of crops, reduces the agricultural chemicals usage amount significantly, and remarkable economical, society, ecological benefits and scientific meaning are arranged.
Embodiment
Select field in flakes, the planting type that keeps corn and potato, between corn and the corn, spacing in the rows between potato and the potato, line-spacing and density is cultivation method routinely all, line-spacing between corn and the potato is 30-60cm, potato is sowed 20-35 days in advance than corn, and corn variety is that plant height surpasses all kinds of 1.5 meters.Corn and potato adopt different rows than intercropping: its row can in the ranks change 2～4 than potato, intercropping 2～4 row corns.The line-spacing of corn is 30～60cm, and spacing in the rows is 30～50cm; The line-spacing of potato is 30～60cm, and spacing in the rows is 30～50cm.
Embodiment:
1, suitable corn of research and potato diversity growing are controlled main disease crop combination, determine the suitable multifarious best cropping pattern of crops.Through the multiple spot test, filtered out the diversity growing combination of 4 kinds of corn and 3 kinds of potato.Finished the test of 5 species diversity cropping patterns, A, 2 row corn covers, 2 row potatos; B, 2 row corn covers, 4 row potatos; C, 3 row corn covers, 3 row potatos; D, 4 row corn covers, 2 row potatos; E, the 4 row potato tests of 4 row corn covers.F, plant corn only.The result shows that the cropping pattern of 2 row corn covers, 2 row potatos is best to the corn southern leaf blight preventive effect, and the cropping pattern of 4 row corns, 4 row potatos is best to corn northern leaf blight preventive effect, and wherein the cropping pattern grain yield of 2 row corns, 2 row potatos is best.
Table one increasing both production and income and disease situation
2, in Kunming, ground such as Qujing, Red River, the mountain of papers different rows of having carried out corn and potato than, different cultivars to corn northern leaf blight and southern leaf blight, the control effect research of potato late blight.PRELIMINARY RESULTS shows, in Kunming, ground such as Qujing, Red River, the mountain of papers different rows of having carried out corn and potato comprises blade dewdrop, humidity, illumination and temperature than the field microclimate research of, different cultivars.Observe statistics from field microclimate, by of the increase of different planting proportions with the corn line number, the increasing of inner shade rate, humidity increases gradually, adopts after the diversity cultivation, and warm between plant, wet, illumination can reduce the condition that disease takes place with respect to clean kind of corn.
Table two field humidity, illumination, dewdrop situation
3, carry out large tracts of land corn potato and optimized the main disease experiment and demonstration of plantation control
In Kunming, area such as Qujing, the Baoshan, Red River, Yuxi finishes 116.2 ten thousand mu of corn and potato diversity companion planting experiment and demonstrations, experiment and demonstration is the result show: corn and the companion planting of potato diversity reach about 70% the control efficiency of corn northern leaf blight and southern leaf blight, mu produces more food about 10%, reducing the agricultural chemicals usage amount is more than 50%, increasing peasant income 50-80 unit has produced tangible economy, society and ecological benefits.
