Abstract

The invention discloses a method for efficiently interplanting purple potatoes, which belongs to the technical field of crop cultivation. The method comprises the steps of soil preparation, base fertilizer application, soil piling, field planting, managing, and the like. According to the invention, under-forest blocky land resources can be effectively utilized, and the utilization rate of fertilizers is improved; the area can be covered by sweet potato vines on the land surface can be increased, so that the leaf area index is increased; potato tubers are better in appearance; and purple potatoes are higher in yield and higher in anthocyanin and selenium element content.

Description

The method of the purple potato of a kind of efficient interplanting

Technical field

The invention belongs to technical field of crop cultivation, be specifically related to the method for the purple potato of a kind of efficient interplanting.

Background technology

Purple potato is again black potato, and potato meat is that purple is to darkviolet.Purple potato happiness temperature climate environment, cauline leaf suitable growth temperature is 18 ~ 25 DEG C, and temperature stops growing lower than when 15 DEG C.Block root the most suitable growth ground temperature is 22 ~ 24 DEG C, and ground temperature expands lower than stopping when 20 DEG C.Purple potato belongs to short day crop, needs illumination abundance, intensity large.Purple potato has outside the protein of common Ipomoea batatas, starch, pectin, cellulose, amino acid, vitamin and several mineral materials, is also rich in selenium element, ferro element and anthocyan, ranks first in the anticancer vegetables that Japanese national vegetables DKFZ announces.In addition, purple potato also can be removed the peel oven dry pulverizing aft-loaded airfoil and become powder, and color and luster is attractive in appearance, nutritious, is fabulous raw materials of food processing, can be used as major ingredient or the batching of various cake.Purple sweet potato is also by one of primary raw material becoming anthocyan simultaneously.Purple potato, from stem apex tender leaf to potato block, all has certain health care functions, is the food in current nuisanceless, green, organic food.

Purple potato in Guangdong, Guangxi, Hunan, Hubei, Fujian, Sichuan, Yunnan, Guizhou, Shandong, Jiangxi, the subtropical zone such as Southern Shaanxi extensively plant, mainly take ridge culture, ridge culture is applicable to tracts of land cultivation, and inadaptable to cultivate with the idle soil of fragmentation, utilization rate of fertilizer is not high simultaneously, purple potato proterties is irregular, different sizes.

Summary of the invention

The object of the invention is for above-mentioned defect, provide the method for the purple potato of a kind of efficient interplanting, the method utilizes the idle land resources of fragmentation, and improve the utilization rate of fertilizer of purple planting potato, potato block proterties is better, and output is higher.

To achieve these goals, this invention takes following technical measures:

1) wholely: select middle-high altitude area crown density lower than 0.5 Hetaoyuan in young age, soil thickness is not less than 80cm, loam or sandy loam, and soil deeptillage 30cm after November walnut fallen leaves, ploughs under Walnut Leaves in soil, survive the winter, rake by the end of March at the beginning of 4 months;

2) basal dressing: after the previous year, purple potato was gathered in the crops, be 3cm particle by climing for potato pulverizing, by following weight proportion configuration base manure: the weight ratio of animal manure 50%, dish or tea cake fertilizer 20%, the climing particle 20% of potato, N:P:K is the composite fertilizer 10% of 5:2:5, by base manure Homogeneous phase mixing, retting, fermentation corruption, then be 60cm according to horizontal and vertical distance to carry out point-like and discharge base manure, often base manure 1.5kg is discharged at place, and be diametrically the toroidal of 30cm, thickness is 5cm.

3) mound is built: build mound around base manure, be wrapped in by base manure in mound, mound is coniform, and base diameter is 40-50cm, high 30cm;

4) field planting: early April field planting, by mound midsection gap, plants into mound by 3/5 of purple potato seedling, compacting;

5) manage: check in time and survive situation and after-culture, guide that potato is climing radially down climbs from mound center, start after the climing 20cm of growing to of potato to carry rattan every month 1 time, impel purple potato tuber growth;

6) gather in the crops: gather in the crops by the end of October.

Compared with prior art, advantage of the present invention is:

1. there is the allelopathy effect be very conducive in walnut woods to the growth of purple potato, walnut Leaf Litter Decomposition thing is also favourable to purple potato growth, and in the past few years walnut woods extensive development, west place in Hubei middle-high altitude area walnut forest land is selenium-rich soil simultaneously, is conducive to purple potato and absorbs selenium element.

2. animal manure, dish cake fertilizer, tea cake fertilizer, potato is climing all gathers materials on the spot, and potato climing-livestock-animal manure-purple potato cultivation, form circulation, N:P:K is that the composite fertilizer of 5:2:5 is conducive to anthocyan and is formed.

3. mound is more conducive to sylvan life fragmentation land resources utilization relative to ridge culture, increases the climing soil surface area that can cover of potato, thus increases leaf area; Base manure is placed on below mound simultaneously, decreases nutrient loss, and improve utilization rate of fertilizer, because purple potato has to fertilizer, therefore purple potato grows all downwards, and potato block is all in straight round bar shape, and shape is more regular.

General branch, this method is more adapted to the purple potato of underwood planting, and potato block product are better mutually, and output is higher, purple sweet potato anthocyanin and selenium constituent content higher, gather in the crops potato block more saving of labor simultaneously.

Embodiment

Below in conjunction with specific embodiment technical scheme of the present invention done and describe in detail further.

Embodiment 1

Following examples are all implemented in Yang Xi town, Yun Yang district of Shiyan City of Hubei Province, and concrete steps are as follows:

1) wholely: select middle-high altitude area crown density be 0.4 Hetaoyuan 1333m in young age ²(amount to net area 800m ²), soil thickness 80 ~ 90cm, soil property is loam, and the rear soil deeptillage 30cm of walnut fallen leaves in November, ploughs under Walnut Leaves in soil, survive the winter, rake by the end of March at the beginning of 4 months;

2) basal dressing: after October the previous year after purple potato results, be 3cm particle by climing for potato pulverizing, by following weight proportion configuration base manure: the animal manures such as sheep 50%, the climing particle 20% of tea cake fertilizer 20%, potato, composite fertilizer 10% (N:P:K=5:2:5), base manure is shifted to an earlier date Homogeneous phase mixing, retting, fermentation corruption, then be 60cm according to horizontal and vertical distance to carry out point-like and discharge base manure, often base manure 1.5kg is discharged at place, and be diametrically the toroidal of 30cm, thickness is 5cm.。

3) mound is built: build mound around base manure, be wrapped in by base manure in mound, mound is coniform, base diameter 40-50cm, high 30cm;

4) field planting: field planting on April 5, first with little spades from cone mound midsection gap, plant into mound by 3/5 of purple potato seedling, compacting;

5) manage: April checks the situation of surviving and after-culture in time, guide that potato is climing radially down climbs from mound center, start after the climing 20cm of growing to of potato to carry rattan every month 1 time, impel purple potato tuber growth.

6) gather in the crops: October 25 gathered in the crops, and both hands catch the climing base portion of potato, up one carry gently.Obtain purple potato 2830kg, average 2265kg/666.7m ².

Embodiment 1 contrasted with adopting traditional ridge culture planting, cultivated area is 800m ², the results are shown in following table.

The effectiveness comparison of table 1 the present invention and traditional ridge culture planting

Note: leaf area index is in unit area, the gross area of plant leaf blade and the ratio of land area, the present embodiment refers to the ratio of leaf area and the land area recorded after purple potato cultivates 120 days.
