Description
Technical field
The present invention relates to the cultivation method of a kind of sweet potato, be specifically related to a kind of summer, high-yield cultivating method that sweet potato is planted in autumn planting, belong to agricultural cultivation technical field.
Background technology
Sweet potato has another name called sweet potato, Ipomoea batatas, pachyrhizus etc., and belonging to Convolvulaceae sweet potato genus sweet potato kind, is annual herb plant.Sweet potato happiness high temperature strong sunshine, according to test, between breeding time >=15 DEG C of accumulated temperature more than 1000 DEG C, breeding time, 100 ~ more than 120d, just easily obtained higher output.Yin Xia, autumn air temperature are from high to low, rainfall from more to less, whole breeding time is sunny, solar radiant energy is large, and effective accumulated temperature is many, and fertility prometaphase temperature is higher, be beneficial to cauline leaf growth, the fertility intermediary and later stages, day and night the temperature difference was large, and be beneficial to potato block and expand, the high yield for sweet potato creates good climatic factor.
Current agricultural planting industry utilizes the spatial distribution of the conceptual approach of location quotient 17 kinds of large classes of crops and the evolution of various places agricultural planting structure, has resolved reason and the power of Chinese agriculture pattern of farming distribution and variation from natural cause and economic factor two aspect.The Main Conclusions drawn is that the spatial distribution of Chinese agriculture pattern of farming is mainly determined by natural conditions, the result of change of its distribution then mainly economic behaviour; The quantity of the same land resources per capita of labor-intensive planting proportion is negative correlation, and the quantity of the same land resources per capita of planting proportion of land-intensive is proportionate; Urbanization and population development determine the distribution and variation of Vegetable produce, and urbanization also affects the change of the cropping index of various places.Propose government should strengthen countermeasures such as the status analysis of various market for farm products and information services.
Patent CN201310634217.3 discloses the kind cultivation technology of a kind of crops, be specifically related to the cultivation method of the super purple sweet potato of a kind of per mu yield ten thousand jin, super purple sweet potato is utilized to have growing way strong, resistance to lean, germinating morning, tender stem look purple is green, tendril is sturdy, damage by disease and insect is few, and to typhoon and heavy rain resistance, also comparatively slight by natural calamity, the features such as wide adaptability; By selecting, creating super purple sweet potato milpa; Adopt germination vernalization condition and method, cultivate super purple sweet potato strong sprout by super purple sweet potato kind.
The present invention selects from the Fruit variety of sweet potato, nursery, plot, whole with furrow, plant, field management, the extermination of disease and insect pest, the aspect such as results sketch sweet potato in summer, fall planting high-yield culture technique; There is not yet relevant report at home and abroad at present.
Summary of the invention
The object of the present invention is to provide a kind of summer, high-yield cultivating method that sweet potato is planted in autumn planting, specifically select from the Fruit variety of sweet potato, nursery, plot, whole with furrow, plant, field management, the extermination of disease and insect pest, the aspect developing sweet potato such as results the summer, autumn high-yield cultivating method.
In order to achieve the above object, the technical solution adopted in the present invention is:
A high-yield cultivating method for sweet potato is planted in summer, autumn planting, and concrete steps comprise:
(1) improved seeds are selected: select output high, swollen good under potato shape, per unit area yield can more than 30t/hm
2sweet potato kind;
(2) high-quality strong sprout is cultivated: the potato block of the excellent sweet potato selected by step (1) does potato seed, the nursery of potato block is carried out at the beginning of mid or late March to 4 month, the wide 1.2m in seedbed, zanjon height furrow, interval 5 ~ 10cm between potato block, sequence earthing 3 ~ 5cm after potato seed, the bonnet 1 layer of straw that water is incubated that anti-grass is short emerges, land for growing field crops potato seed about 225 ~ 300kg/hm
2, mid or late May, carry out heeling in numerous seedling, seedling transplanting can be cut;
(3) selection of field: select more than deep, the middle fertility of soil layer, the soil is porous, irrigation and drainage are convenient, air capacity of soils is strong sandy loam or loam;
(4) wholely with rise furrow: plant sweet potato and should plough deeply furrow, accomplish the wide bag ditch of the narrow furrow of furrow zanjon 1.1 ~ 1.2m, the high 30 ~ 40cm in ridge, executes farmyard manure 15t/hm
2, superphosphate 600kg/hm
2, potassium chloride 150kg/hm
2make base manure, then execute 3.6% benthiocarb granule or 5% phoxim granule 37.5kg/hm
2insect protected;
(5) plant: by the end of July at the beginning of 8 months, carry out individual plant transplanting, transplanting spacing in the rows 15 ~ 20cm, transplanting 4.5 ten thousand ~ 6.0 ten thousand strains/hm
2;
(6) field management: carry out and apply fertilizers scientifically, aerobic irrigation, and the extermination of disease and insect pest;
Field management described in step (6) divides early stage, mid-term and final-period management, and early stage should look into seedling fill a vacancy for planting rear about 7d, and prevent from being short of seedling disconnected ridge to save seedling from damage, this stage should keep furrow face ground moistening, and after inserting, about 15d combines and waters, and uses urea 120 ~ 150kg/hm
2and potassium chloride 150kg/hm
2, and carry out the 1st intertillage; Mid-term is that after transplanting, the emphasis of this phase of 20 ~ 50d is the climing short branch of control, and after transplanting, about 30 ~ 40d carries out brokenly ridge solarization in vain, and enriches mixed organic manure 750kg/hm
2and potassium chloride 300kg/hm
2; Later stage is that potato block expands, the important period of nutrient component steering block root accumulation, and emphasis controls acrial part and under ground portion balanced growth by water management.
Tool of the present invention has the following advantages:
The sweet potato of method of the present invention plantation, method is easy, easily operates, and the sweet potato of plantation creates the domestic and international new record that sweet potato per mu yield surpasses ten thousand jin, obtains shape large, the sweet potato of high-quality, high yield, improves the economic benefit of agricultural production plantation.
