Embodiment 1
[0033] A kind of sweet potato high-yield cultivation method, concrete steps are as follows:
[0034] (1) Selection of improved varieties: for high-yield sweet potatoes, improved varieties are the key. According to the use and market, the improved varieties should be selected according to local conditions, especially the effect of increasing production of new varieties is particularly significant;
[0035] (2) Cultivate strong seedlings: Strong seedlings have many and well-developed root systems. After planting, they will live quickly and have many roots and tubers. Short, thick leaves, moderate size, with the characteristics of this variety, no disease, more milk in the cut, 50-70cm long vines, more than 0.5cm thick stems;
[0036] 1) Seedbed selection, choose leeward and sunny, convenient drainage and irrigation, fertile soil, no sweet potato in three years as a seedbed, plant a large field with a sufficient seedbed of 2.5-3m 2 ;
[0037] 2) Sowing at the right time, in the...

Abstract
The invention discloses a high-yield cultivation method for sweet potatoes. The high-yield cultivation method comprises the following concrete steps: I, choosing an improved variety: the improved variety is the key to produce the sweet potatoes at high yield; according to the use and the sale, the improved variety is chosen in the light of local conditions, and especially, the new variety is particularly obvious in yield-increasing effect; II, cultivating strong seedlings: the roots of the strong seedlings are numerous and developed, after being planted, the seedlings survive quickly, and hair roots bear the sweet potatoes fruitfully, which lay the foundation for full stands, strong plants, numerous potatoes and big potatoes; the standards of the strong seedlings are shown as follows: thick and strong stems, short internodes, fat blades and moderate sizes, with the features of the improved variety, no diseases, plenty latex of cuts, 50cm to 70cm of vine length and more than 0.5cm of stem thickness; III, transplanting in real time; IV, performing scientific management; V, harvesting the sweet potatoes when potato leaves start to turn yellow and the air temperature is below 20 DEG C, wherein the sweet potatoes require to be harvested before the end of October, and potato tubers should be prevented from being damaged by digging during harvesting. The high-yield cultivation method disclosed by the invention has the advantages that seeds are saved by more than 1 / 3, the buried section number of seedling vines is large, covering of soil is slight, the soil temperature is high, and after ventilation, the survival rate is high.
Description
technical field [0001] The invention relates to the technical field of planting, in particular to a high-yield cultivation method for sweet potatoes. Background technique [0002] At present, the conventional field sweet potato cultivation method mainly adopts the direct insertion cultivation method of one leaf and one node, that is, the potato tendrils are arranged, divided into two to three leaf nodes and cut into sections, leaving the uppermost leaf in each section, and cutting the lower leaves. When planting, the part with leaves on the ground is about 3-5 cm, and the remaining parts with leaf nodes are all submerged in the ground. The first is that the amount of seeds used is large, and the second is that the sweet potato seedlings have many wounds, are susceptible to infection, have a low survival rate, slow tree growth, and inconsistent knot positions of the sweet potato, resulting in inconsistent size of the sweet potato, which seriously affects the yield.
