For ridge cultivation, some increase the cultivation density to 5000-8000 plants / mu (667m 2 ), however, this is unreasonable for the cultivation method aimed at cultivating shoot tips
Firstly, the cultivation density is too low, and the land utilization rate is low, which affects the yield of shoot tips; secondly, the ridges cause height difference, which is inconvenient for mechanical shoot tip harvesting, and the cost of manual harvesting is high, the efficiency is low, and it will also trample the plants, affecting regeneration; again , affected by seasonal restrictions and climate change, it is impossible to carry out perennial production and cannot meet the annual market demand
[0005] At the same time, conventional field planting can only pick potato tips from the end of June to October, which cannot meet the annual market demand throughout the year
In addition, due to low temperature and high humidity, the survival rate of potato seedlings is greatly reduced, and there is a serious shortage of seedlings. Many potato seedlings cannot survive the winter safely, and the benefits are reduced.

Embodiment 1
[0038] Ecaishu No. 1 was selected as the vegetable sweet potato variety. The test site was Qianhu Village, Jinkou Street, Jiangxia District, Wuhan City, Hubei Province. The test period was 2016. Five sunny steel frame greenhouses participated in the test, with a size of 8m*60m. The average area is 480m 2 .
[0039] The specific method is as follows:
[0040] Dry the fields and prepare the land, and apply organic fertilizers as base fertilizers.
[0041] Around October 20th, cut the stem and leaf vegetable seedlings with old thick leaves and strong growth, and transplant them into the greenhouse. The cuttings are inserted into the soil for about 5-6 nodes, and the row spacing between plants is 20cm*20cm.
[0042] Cover the first layer of greenhouse film around October 25th, open the greenhouse for ventilation at 8:00-9:00 in the morning, close the greenhouse film at 4:00-5:00 in the afternoon, and close the greenhouse in cooling weather.

Abstract
The invention provides a three-film seedling protection method for sweet potatoes used as stem and leave vegetables. The method comprises the following steps of (1) transplanting seedlings of the sweet potatoes for sweet potatoes used as stem and leave vegetables in a greenhouse; (2) covering the greenhouse with a first layer of greenhouse film additionally a week before Frost's Descent, covering the greenhouse with a second layer of greenhouse film additionally a week before Great Snow, and when the minimum outdoor temperature drops to 0 DEG C, covering the greenhouse with small arch shed film additionally; (3) after the temperature rises, removing the layers of the film sequentially, and performing shed covering management on the seedlings of the sweet potatoes for sweet potatoes used as stem and leave vegetables. According to the three-film seedling protection method for the sweet potatoes for sweet potatoes used as stem and leave vegetables, the seedlings are protected by using the three-film method, the phenomenon of insufficiency, caused by low temperatures and high humidity, of the seedlings can be avoided more effectively, so that safe wintering of the potato seedlings is achieved; besides, early marketing of the sweet potatoes can be achieved, the annual supply of green potato tips is ensured, and the purpose of high benefits is obtained.
Description
technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for preserving seedlings of sweet potatoes for stem and leaf vegetables with three membranes. Background technique [0002] Sweet potato is a vegetatively propagated crop with strong drought and humidity tolerance, strong regeneration ability, wide adaptability and easy cultivation. Hubei Province belongs to the potato area in the middle and lower reaches of the Yangtze River. The average temperature is relatively high, the frost-free period is long, the resources of temperature and light are abundant, and the annual rainfall is abundant, which is very suitable for the growth of sweet potatoes. [0003] The sweet potato for stem and leaf vegetables has the characteristics of fast growth of stem and leaf, strong regeneration ability, resistance to diseases and insect pests, strong adaptability, and tolerance to fertilizer and water. The stem tips are les...
