Simple storage method of seed taros

Abstract

The invention relates to a simple storage method of seed taros. The method comprises the following steps: after taros are harvested in autumn and winter, conveying seed taro bulbs into a greenhouse, stacking the seed taro bulbs and soil with the relative water content of 50-60% in the greenhouse in a layered manner, covering the peripheries of the stacks with soil with the thickness of 5-10cm, covering the stacks with black plastic films, and then sealing the greenhouse; and uncovering the films at two ends and two sides of the greenhouse for ventilation and cooling in small sunny spring weather or with the rising of the air temperature after spring. Through the method, the bulbs can be prevented from being frozen and rotten, the bulbs can be prevented from losing water and being wizened due to excessive loss of soil moisture, the seed taros can be conveniently taken out for sale according to market demands, the seed taros can be prevented from sprouting in advance due to proper temperature and humidity, and the seed taros can be stored in the first ten-day period of April.

Description

technical field [0001] The invention relates to a simple storage method for taro seeds, belonging to the technical field of agricultural (vegetable) cultivation. Background technique [0002] Taro is rich in nutrition and can be used as a food economic crop or as a vegetable. Because its product corm is rich in starch, it is more resistant to storage, and the risk of planting is lower, and the scale of cultivation is expanding year by year. In the 8th issue of "Yangtze Vegetables" in 2018, the introduction and cultivation technology of Guiyu No. 2 Lipu taro studied by Zhu Lili and others was disclosed. The seedlings were raised in the greenhouse in early spring and transplanted in the open field when the external temperature was suitable. The introduction of Lipu taro to Yangzhou, Jiangsu, which has a short suitable growth period in the open field, was successful. [0003] Taro bulbs begin to germinate at a temperature of 13-15°C, and the optimum temperature is about 20°C. ...

AI Technical Summary

Problems solved by technology

The above-mentioned simple storage techniques only provide some indicators for the temperature conditions of the storage environment. However, in the middle and lower reaches of the Yangtze River, there are many cloudy and rainy days in winter and spring, and strong cold waves below -5°C often occur. Stacking and covering soil or digging trenches, or directly leaving fields and covering soil for winter storage without harvesting in autumn, or indoor sand storage or storage, even if the above-mentioned outdoor open field stacking or covering with soil and then covering with plastic film and other rain shelter measures, it is possible Due to the occurrence of strong cold waves below -5°C, freezing damage is formed, resulting in a loss rate of 30-40%

However, the above-mentioned public documents only have a vague concept of the humidity of the storage environment, and there is no clear threshold range. In practice, it has been found that excessive water loss and shriveling are caused by too low soil humidity, resulting in a decrease or even loss of yield benefits; If the humidity is too high and encounters low temperature and strong cold wave, it will suffer from chilling damage or even freezing damage and rot, but if it encounters a suitable temperature, it will quickly sprout and take root. The strong cold wave in winter and the Xiaoyangchun climate in early spring are common phenomena in the middle and lower reaches of the Yangtze River.
