Abstract
Disclosed is a sweet potato and corn interplanting method. The method is implemented in late April every year and comprises the steps of (1) performing ridging after field tillage; (2) planting sweet potato plantlets at ridge tops, covering the roots of the sweet potato plantlets with soil of 5-8 cm to expose plantlet tips out of the soil for 3-5 cm, wherein the interval of the sweet potato plantlets is 18-25 cm; (3) planting corn in a mode of 2-3 seeds per hole, covering soil and enabling the interval between every two holes to be 25-30 cm. Tested by multiple experiments, the sweet potato and corn interplanting method can increase the net yield of corn by 50% under the condition of maintaining the yield of sweet potato, thereby increasing the income of grain for peasants and enhancing the economic benefits of dry lands. Further, according to the sweet potato and corn interplanting method, plantlet mulching is utilized to maintain moisture and temperature of breeding fields; restored nursery breeding is utilized to improve the emergency rate and to ensure orderly supply of the sweet potato plantlets, so that the labor intensity of the peasants can be reduced.
Description
Technical field
The present invention relates to a kind of agricultural plantation technology field, particularly the cultivation method of a kind of sweet potato and interplanting corn.
Background technology
For implementing the policy that " the many receipts of high yield " and " bringing in bigger crops by expanding the snow area " develop simultaneously, suit measures to local conditions, giving priority to.Without waste available area, to reform cropping system, should extend the areas for multiple cropping, carry out intercropping, improve culture technique, it is main for improving per unit area yield, mix interplanting between implementation crop and extend the areas for multiple cropping, to improve land utilization rate, an importance of Ze Shi China present stage cropping system reform.
Corn, also known as maize, celestial wheat, maize, maize, ear of maize, is important cereal crops and important feed resource, is also cereal crops that whole world gross yield is the highest, more taller than rice yield.Corn is annual gramineae herbaceous plant simultaneously, and during plantation, the occupation of land time is longer, and corn line space when planting is also comparatively large, and for this reason, Maize Seedlings also has remaining space greatly to can not get good utilization.Comparatively speaking, cause unit are economic benefit relatively low.And sweet potato is also annual herb plant, crawl in the majority on the ground during growth, the space utilization rate of top, plantation arable land is lower.
In recent years, the reduction year by year of corn/sweet potato cultivated area, in the cultivated land resource utilized, ubiquity the low problem of development of exploitation level, and arable land cropping index is not high is one of reason that development of exploitation level is low.Sweet potato interplant corn not only extends effective utilization in soil in time, and spatially achieves solid growth.The pattern of companion planting cultivation improves arable land cropping index effective method, but traditional sweet potato/corn intercropping and interplanting growing and cultivation method can not improve the economic benefit in arable land.
Crops interplant technology, is utilize the Time and place of plant growth harvest poor, wants benefit, increase substantially labor productivity to solid, alleviates the new technology that crops strive ground contradiction.Technology and the model study of carrying out sweet potato/corn intercrop thing interplanting are developed, the raw material not only solving biomass energy and the dull season eaten, and be one and take into account energy security, grain security, make full use of soil, to raise the multiple-cropping index, the significance such as short agriculture increasing both production and income.
Summary of the invention
The object of the invention is for existing nonirrigated farmland sweet potato and corn intercropping and interplanting growing and cultivation method is unreasonable, the technical problem, the nonirrigated farmland sweet potato providing a kind of output high, time saving and energy saving and the corn intercropping and interplanting growing and cultivation method that yield poorly.
Technical scheme of the present invention is as follows:
A cultivation method for sweet potato and interplanting corn, in annual plantation the middle ten days and the last ten days in April, comprises following steps:
(1) ridging is carried out by after ploughing soil;
(2) get the sweet potato seedling that length is 15 ~ 20cm, the top, ridge in step (1) is planted, and plants sweet potato shoot root portion and covers soil 5 ~ 8cm, seedling Caudad is exposed earth 3 ~ 5cm, every strain sweet potato seedling spacing 18 ~ 25cm;
(3) seeding corn, every cave kind 2 ~ 3 maize seeds, blinding, spacing 25 ~ 30cm between two caves.
Wherein, the sweet potato seedling described in step (2) is that the cultivation of sweet potato block forms, and step is:
(4) mixedly on soil farmyard manure 78000 ~ 97500Kghm is executed
-2, carry out rear ridging of turning over, row spacing 87 ~ 93cm, the high 28 ~ 31cm in ridge;
(5) ditch is backed down in ridge, by pretreated potato block in starting seeding, every potato interblock gap 13 ~ 19cm, blinding 3 ~ 8cm, seeding bonnet mulch film to early April by the end of March;
(6) after germination and emergence, rupture of membranes, waters and urges seedling, cuts Miao Fuyu as height of seedling >=30cm;
(7) garden of collecting seedling is educated again in the nonirrigated farmland of the close water source of selection, fertile soil, and fertilising plays the wide ridge of 1.0m after turning over, and ditching by spacing in the rows is 17 ~ 20cm transplanting, when sweet potato seedling grows to 20 ~ 30cm, be seedling;
Wherein, a line corn is planted every 2 ~ 3 sweet potato ridges, ridge in step (3).
Wherein, corn planting described in step (3) is on the face, ridge that 1/2 ridge at the bottom of ridge is high.
Wherein, the potato block pretreatment described in step (4) soaks 10 ~ 12min for potato seed being placed in 25% carbendazol wettable powder, 500 ~ 700 times of liquid or 50% topsin wetting powder, 400 ~ 600 times of liquid.
Wherein, the ridging described in step (1) is by 12000 ~ 15000Kghm on soil
-2fertilising post-trenching, ditch base fertilizer 400 ~ 500Kghm
-2, execute rear ridging, ditch base fertilizer earth renovated, sweet potato distance between the ridges 0.8 ~ 1.3m.
Wherein, after cutting seedling in step (6), Nitrogen Top Dressing urges seedling, generally executes urea 150Kghm
-2.
Wherein, the fertilising described in step (7) is for executing the quality fertilizer 22500 ~ 30000Kghm that becomes thoroughly decomposed
-2, urea 60 ~ 75Kghm
-2, superphosphate 300 ~ 375Kghm
-2, potassium sulfate 225 ~ 300Kghm
-2make base manure.
Wherein, 10 ~ 14d intertill and clean tillage after transplanting in step (7), by 75 ~ 90Kghm
-2the short Miao Kuaifa of fertilising.
Beneficial effect of the present invention:
The inventive method takes the row spacing of rational spacing in the rows and sweet potato/corn intercropping and interplanting, greatly enhance the cropping index in nonirrigated farmland, the present invention is verified by test of many times, the output of pure corn yield increasing 50% when yield of sweet potato is constant, add the income of peasant's grain, improve the economic benefit in nonirrigated farmland.Further the present invention uses plastic film, keeps moisture and the temperature of nursery; Adopt multiple Seedlings nursery nursery to improve emergence rate, ensure the neat supply of potato seedling, alleviate the labour intensity of peasant.
