Abstract
The invention discloses a method for controlling Asiatic corn borers through species diversity planting of canes and corns. The method comprises the following steps of: interplanting the corns on ridge edges of plant canes or ratoon canes; selecting the canes from local mainly-popularized improved varieties, seeding winter-planted canes from the beginning of November to January of the next year, seeding spring-planted canes from the beginning of February to the end of March, and then seeding the corns, wherein the line spacing of the canes is 90-100cm, about 150000 buds of the corns are planted on per hectare of a land, the density is kept to be up to 82500-90000 productive tillers/ha, the corns with early-maturing, short-straw and compact-plant type varieties are selected; digging ponds and sowing at the ridge edges of the canes, wherein the pond spacing is 35-40cm, two plants are planted in each pond, and the planting density is kept to be up to 27000-33000 plants/ha. The effect for controlling the Asiatic corn borers through the species diversity planting of the canes and the corns is up to 60-70%.
Description
Technical field
What the present invention relates to is the method for a kind of sugarcane corn diversity growing control Asiatic corn borer.
Background technology
Crop interplanting interplanting is in the existing long history of China, China agricultural 1985-1995 10 in the period of, it is 70% that the cropping system measure improves the contribution rate that output is improved.Why China can create world's miracle with the population of having supported the world 22% less than the arable land in the world 7%, also inseparable with the intercropping and interplanting multiple cropping.This species diversity intercropping and interplanting has resources such as intensive utilization arable land, labour, nutrient, moisture, light and heat, improves its availability, reduces damage by disease and insect, realizes the advantages such as high-yield and high-efficiency of agricultural.
Corn is the second largest crop that China's cultivated area, gross yield and per unit area yield all are only second to paddy rice, Yunnan, Sichuan, Heilungkiang, Jilin, Liaoning, the Inner Mongol, Hebei, Shandong, Shanxi, Shaanxi, Henan, etc. the corn seeding area in 11 provinces all at 1,000,000 hm
2More than, total sowing area is 2172.91 ten thousand hm
2, account for 80.56% of the total sowing area of national corn.Corn borer is the primary pest of corn, and is very big to output and quality influence.General time spring corn is injured and the underproduction about 10%, and outbreak year can make the corn underproduction more than 30%, brings about great losses.
Corn borer is the primary pest of corn, and it is the main existing a lot of reports of method for integrated control that its pests occurrence rule reaches with the chemical control.Like Liu Xiaofeng, Wang Jun report Xinmin City, Shandong corn borer pests occurrence rule and Preventing Countermeasures; New feature and Preventing Countermeasures that Sun Jianwu report Lingbi County, Anhui Province corn borer is taken place; The generation of report corn borers such as Li Lizhi with observe and predict; Li Zhengyue and the application of Lu Meirong report effective accumulated temperature method in Yunnan Asiatic corn borer Ostrinia furnacalis (Guenee) research, the Yu Hongbin report is with the method for oophagous trichogrammae control of maize snout moth's larva; But the method with the crop diversity growing is prevented and treated Asiatic corn borer also is not reported at present.
With the chemical pesticide control is main integrated control technique: utilize the light that becomes, the chemotaxis of corn borer, before the corn borer adult lays eggs, trap and kill; Protection utilizes oophagous trichogrammae, the strict natural enemies such as fly, white muscardine fungi of posting to control corn borers in the farming operation; Prevent and treat with chemical pesticide during big the generation.But be prone to pollute environment, people, animal safety is threatened.
Summary of the invention
Technical problem to be solved by this invention is that the deficiency that is directed against prior art provides a kind of crop diversity growing that utilizes to control the corn primary pest---the method for Asiatic corn borer.
Technical scheme of the present invention is following:
The method of a kind of sugarcane corn diversity growing control Asiatic corn borer, the interplanting corn on the limit, ridge of new plant cane or stubble cane; Sugarcane selects for use the locality to promote mainly breeding, and the winter plants sugarcane first arrival in November and sows by the end of January next year, and the first arrival in February of spring planting sugarcane is sowed by the end of March, sows corn then; The sugarcane line space is 90～100cm, about per hectare kind 150000 buds, guarantees that density reaches 82500～90000 productive tiller/ha; Corn is selected the kind of precocity, short bar, plant type compactness; Play pool sowing in limit, sugarcane ridge, the pool is apart from 35～40cm, and 2 strains of every pool guarantee that planting density reaches 27000～33000 strains/ha.
The inventor discovers that the effect of sugarcane corn diversity growing control Asiatic corn borer reaches 60～70%.
Embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
Sugarcane corn diversity growing is interplanting corn on the limit, ridge of new plant cane or stubble cane.Sugarcane selects for use the locality to promote mainly breeding, the Guangdong sugar 93/159 wide like new horizontal sliding.Winter plants sugarcane first arrival in November and sows by the end of January next year, and the first arrival in February of spring planting sugarcane is sowed by the end of March, sows corn then.The sugarcane line space is 90～100cm, about per hectare kind 150000 buds, guarantees that density reaches 82500～90000 productive tiller/ha.The kind (like cultivated source early No. 1, single No. 4 of meeting etc.) of precocity, short bar, plant type compactness selected by corn or the place precocity is sweet, the glutinous corn variety sowing.Play pool sowing in limit, sugarcane ridge, the pool is apart from 35～40cm, and 2 strains of every pool guarantee that planting density reaches 27000～33000 strains/ha.
Sugarcane corn diversity growing has improved land utilization rate, has controlled corn borer, has reduced production cost, has protected agroecological environment simultaneously again.The inventor discovers that the effect of sugarcane corn diversity growing control Asiatic corn borer reaches 60～70%.
Be injured 31.83 of several decreased average of hundred strain blades are compared in sugarcane corn diversity growing field with corn nonoculture field, control efficiency is 69.91%; The lobus cardiacus phase strain rate of being injured reduces 11.07%, and control efficiency is 61.14%; Moth bar rate reduces 15.74%, and control efficiency is 76.5%; The female fringe rate of being injured reduces 10.8%, and control efficiency is 42.08%.
Sugarcane and corn are all gramineous plants, and the both is a long-stalked crop, but both are different to the requirement of temperature and illumination; Sugarcane only is adapted at the torrid zone and the plantation of south subtropics monsoon climatic region; But at 13 ℃ of germination and emergences, but poor growth, the righttest germination temperature is 30～32 ℃; Require tillering stage daily mean temperature more than 20 ℃, tiller for 30 ℃ and contain most; 12～18 ℃ of shooting stages can slowly extend, and optimum temperature also is 30 ℃; Maturing stage requires temperature gradually to fall, with 13～18 ℃ be advisable [13].The breeding time of sugarcane is long, and is very slow at the low temperature growth period of hot-zone, and the inferior suitable warm area of its growth has been the thermophilic district of corn growth, and the breeding time of corn is short in addition.Therefore can when sugarcane emerges, interplant early ripening maize (about 100 days breeding times), treat that sugarcane length arrives before the envelope row, corn is ripe and harvested.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
