Description
Technical Field
The invention belongs to the technical field of crop cultivation, and particularly relates to a planting method for doubling the yield of sweet potatoes by using a vine cutting method.
Background
The sweet potato is rich in protein, starch, pectin, cellulose, amino acid, vitamin and various mineral substances, and has the reputation of longevity food. The sugar content reaches 15 to 20 percent. Has anticancer, heart protecting, emphysema and diabetes preventing, and weight reducing effects. The Ming Dynasty Li Shizhen Ben Cao gang mu describes the deficiency tonifying, spleen strengthening, appetite stimulating, kidney yin strengthening of sweet potato, and says that the life of people in the sea is long. Sweet potatoes are regarded as good medicines in the traditional Chinese medicine of China.
The root of sweet potato is divided into fibrous root, firewood root and tuberous root, wherein the tuberous root is an organ for storing nutrients, is an edible part and has various shapes such as spindle shape, cylinder shape, spherical shape and block shape. The root tuber also has the characteristic of root sprouting and is an important organ for seedling breeding. Some countries in africa and asia use sweet potatoes as staple food. The sweet potato can also be used for making vermicelli, cake, jam, etc. In industry, sweet potatoes can be used for extracting starch and are widely used in the aspects of textile, paper making, medicine and the like.
Sweet potatoes are used as one of main grains in many countries in the world, and since the introduction of sweet potatoes in the 16 th century, the sweet potatoes are planted in a simple mode, convenient to manage in the field, low in requirement on soil and the like, so that the planting area of the sweet potatoes in the whole country relates to most of China at present, and the sweet potatoes are also used as one of the main grains in some places. However, through observation and visit, the sweet potato planting method generally adopts the traditional 'lazy' mode, i.e. the sweet potatoes are not applied with pesticide and chemical fertilizer from planting to harvesting, and the 'hardy and fast' people in villages can turn over the first vines and the second vines when the sweet potatoes grow vigorously. Since most growers are "self-producing", few people pay attention to the yield of sweet potatoes. The data records that the sweet potatoes need to be grown large and have high yield, and four methods are adopted: seedling inverted planting, terminal bud picking, crack fertilizer filling, plant growth regulator spraying and the like (taken from agricultural small pack basket). Further research is needed to further improve the yield of sweet potatoes by adopting any method.

In view of the above, the invention aims to provide a cultivation method adopting a 'vine cutting method' of sweet potatoes, which controls the vigorous growth of the sweet potatoes, improves the yield of the sweet potatoes and achieves the effect of 'doubling' the actual yield.
In order to achieve the above purpose, the invention provides the following technical scheme:
a sweet potato planting method comprises selecting land, preparing land, ridging, planting, cutting the vines of the sweet potato when the sweet potato enters into the vigorous growth stage, only leaving stem leaves on the ridges, and harvesting after ripening;
preferably, sandy loam or loam with deep soil layer, loose and fertile soil, good air permeability, no industrial pollution source and drainage condition is selected as a planting field;
preferably, the soil preparation mode is deep ploughing and insolation, and the depth of deep ploughing soil is 10-20 cm;
more preferably, the depth of the deep ploughed soil is 15 cm;
preferably, the ridging mode is that the ridge width is 30-35 cm, the ridge height is 20-25 cm, furrows are arranged between adjacent ridges, and the ridge width is 10-15 cm;
preferably, healthy, strong and disease-free sweet potato seedlings are selected, sowed in the first 6 months and the middle ten days, planted in a single row and a single row in one ridge, and the planting distance is 10-20 cm;
preferably, the sweet potato seedlings are watered immediately after being planted, and the relative humidity of soil is maintained to be 60-70%; after 10 days, irrigating in a mode of watering once every other day until the sweet potato seedlings survive;
preferably, when the sweet potatoes grow vigorously, the vines of the sweet potatoes are cut, and only the leaves and stems on the ridges are reserved;
more preferably, in 7-month middle ten days, when the vines of the sweet potatoes grow to be more than 70cm, the vines of the sweet potatoes are cut, and the cutting is carried out once every 15-20 days until 4-5 times of cutting are carried out in 9-month middle ten days;
preferably, after the sweet potatoes are ripe in the middle and last ten days of 10 months, harvesting;
preferably, the sweet potato is sweet potato or purple sweet potato.
Compared with the prior art, the invention has the following beneficial effects:
the invention provides a planting method for doubling the yield of sweet potatoes by using a 'vine cutting method', which is simple to operate and easy to implement. The cutting of the vines of the sweet potatoes controls the vigorous growth, and enables the nutrition absorbed by root systems to be conveyed to the tuberous roots, thereby improving the yield of the tuberous roots. Through field tests, under the condition of no stimulation of additional pesticide, chemical fertilizer and plant growth hormone, the weight of the sweet potatoes and the purple potatoes in an experimental group is nearly doubled compared with that of a control group, and the weight of the sweet potatoes in the experimental group is as follows: the yield of the control group of sweet potatoes is 6.5: 3.6: 1.81, namely the yield is increased by 81 percent; experimental group purple sweet potatoes: the yield of the control group of purple sweet potatoes is 6.7: 3.4: 1.97, namely the yield is increased by 97%, namely the yield of the experimental group of the purple sweet potatoes and the yield of the purple sweet potatoes can be estimated to be 'doubled' compared with the yield of the control group.
In addition, a part of the tender leaves of the cut vines can be eaten as vegetables; the other part can be used as green feed for breeding poultry and livestock; the unfermented poultry and livestock can be used as compost to naturally decay to produce good organic fertilizer, so that the reutilization of agricultural byproducts is achieved.
Detailed Description
The invention provides a sweet potato planting method for solving the problems of wide sweet potato planting management and low yield. By selecting land, preparing land, ridging and planting, when the sweet potatoes enter the vigorous growth period, the vines of the sweet potatoes are cut, only stem leaves on the ridges are left, the sweet potatoes are maturely harvested, the vigorous growth of the sweet potatoes is controlled, the yield of the sweet potatoes is effectively improved, and the yield is doubled.
In the invention, before sweet potato seedling transplantation, soil selection is carried out, and sandy loam or loam with deep soil layer, loose and fertile soil, good air permeability, no industrial pollution source and drainage condition is preferably used as a planting field.

Transplanting and planting in clear weather in the late 6 months and the middle ten days, planting in one ridge and one row and in one row, wherein the planting distance is 10-20 cm, and preferably 15 cm. The sweet potato seedlings are watered immediately after being planted, and the relative humidity of soil is maintained to be 60% -70% so as to ensure survival of transplanted seedlings; and after 7-10 days, irrigating in a mode of watering once every other day until the sweet potato seedlings completely survive.
After the sweet potato seedlings are transplanted, the sweet potato seedlings can go through a rooting and green turning period, a branch and tuber forming period, a stem leaf growth period, a potato block expansion period and a potato block rapid expansion period. When the sweet potatoes grow to the vigorous stage, namely the stem leaf growth/tuber expansion stage, the vigorous growth is controlled by cutting the vines of the sweet potatoes, only the stem leaves on the ridges are left, and nutrition absorbed by root systems can be conveyed to the root tubers, so that the expansion of the root tubers is promoted, and the yield is improved. The method is preferably to cut the vines of the sweet potatoes in the middle 7 months when the vines of the sweet potatoes grow to be more than 70cm, wherein the cutting is carried out once every 15 to 20 days until the cutting is carried out for 4 to 5 times in the middle 9 months.
The method is used for harvesting the sweet potatoes after the sweet potatoes are ripe in the middle and late ten days of 10 months, the method is preferably carried out in the morning on sunny days, and the vines on the ground surface can be completely cut off before harvesting so as to improve the efficiency of harvesting the tuberous roots of the sweet potatoes.
By utilizing the sweet potato planting method, the transplanting survival rate and normal growth of the sweet potato seedlings can be ensured; the method is characterized in that a 'vine cutting method' is adopted after the sweet potatoes grow vigorously, namely in the middle ten days of 7 months, when the vine grows to be more than 70cm, the vine is cut once every 15-20 days until 4-5 times in the middle ten days of 9 months, the vigorous growth of the vine on the overground part of the sweet potatoes can be effectively controlled, the nutrient accumulation of underground tuberous roots is promoted, the tuberous roots are promoted to expand, and the yield is improved.
