Problems solved by technology

[0002] At present, sweet potato cultivation includes several links such as seedling raising, transplanting, field management, and harvesting. The current seedling raising method is: a small plastic shed is placed on the open flat border to heat, and the emergence rate can only reach about 60%. In addition, the mu of sweet potato The output can only reach 3000-3500 kg, the output is not high

Embodiment 1

[0011] Embodiment 1: a kind of high-yield cultivation method of sweet potato, is made up of several links of seedling raising, transplanting, field management, harvesting,

[0012] (1) The time for raising seedlings is in early or late January, and the steps of raising seedlings are as follows:

[0013] a. Germination by electric heating: the first step is to clean up the seedling pond in the plastic greenhouse. The bottom of the pond requires an active soil layer of more than 30cm, mix organic fertilizer and pour enough water; the second step is to arrange the seed potatoes vertically and seal them with fine sand To tighten the gap between seed potatoes, cover them with sawdust or wheat bran to a thickness of 1-2 cm, then cover them with electric blankets, and finally add a small plastic shed; control the temperature at 18-23 ° C, generally 7-10 days to germinate, 15-20 days Seedlings emerge in 1 day, and the emergence rate reaches 80-90%;

[0014] b. Seedling cultivation: A...

Abstract

The invention provides a high-yield sweet potato cultivation method, composed of several links including seedling raising, transplanting and field management, characterized in that: the step of seedling raising is composed of electric heating sprouting and seedling raising, a plastic house covering small plastic sheds and electric blanket coverage are adopted in sprouting, and the rate of emergence reaches 80-90%; and in the process of field management, when potato vines fully cover the ground, vines are put in proper order ridge by ridge, potato vines on one side of a potato ridge are moved to the other side, and the potato vines of every two ridges are put into one furrow with the other furrow exposed, thus improving the heating condition of the potato ridges, enlarging day-and-night temperature difference, accelerating potato tuber enlargement, and achieving the purpose of high yield. Because two layers of plastic sheds and electric blanket coverage are adopted for seedling raisingby electric heating, the seedling raising time can be advanced from the first ten days of March to the first ten days of January (before the beginning of spring), and simultaneously the rate of emergence reaches 80-90%; and because vines are put in proper order ridge by ridge and the heating condition is improved, the yield per mu of sweet potato reaches 4000-4500 kilograms, and the yield is increased by more than 20% compared with traditional methods under the same growing environment and management.

Description

technical field [0001] The invention relates to a sweet potato cultivation method, in particular to a sweet potato high-yield cultivation method. Background technique [0002] At present, sweet potato cultivation includes several links such as seedling raising, transplanting, field management, and harvesting. The current seedling raising method is: a small plastic shed is placed on the open flat border to heat, and the emergence rate can only reach about 60%. In addition, the mu of sweet potato The output can only reach 3000-3500 kg, which is not high. Contents of the invention [0003] In order to improve the seedling raising rate of sweet potatoes and the yield of sweet potatoes, the invention proposes a high-yield cultivation method of sweet potatoes. [0004] The technical solution of the present invention is: a high-yield cultivation method of sweet potato, which is composed of several links of seedling raising, transplanting and field management, and is characteriz...
