Description
Technical Field
The invention relates to the technical field of cassava seed stem preservation, in particular to a cassava seed stem preservation device and a preservation method thereof.
Background
Cassava (scientific name: Manihetesculenta Crantz) erect shrubs, 1.5-3 meters high; the root of the block is cylindrical. The leaf paper is made of paper, the outline is nearly circular, the palm shape is deep-split to a few degrees to the base part, 3-7 split pieces are formed, the shape is inverted to be a narrow ellipse, and the top end is tapered; the petiole is 8-22 cm long, is shield-shaped and grows, and has no obvious thin edge; the cassava has strong adaptability, drought resistance and barren resistance. In areas with the average annual temperature of more than 18 ℃ and the frost-free period of more than 8 months, the plants can be planted in mountainous regions and plain regions; the rainfall is 600-6000mm, the altitude of the tropical zone and the subtropical zone is below 2000m, the soil can grow in the places with the pH value of 3.8-8.0, and the soil is most suitable for the land with the average annual temperature of about 27 ℃, the average daily temperature difference of 6-7 ℃, the annual rainfall of 1000-2000mm, the distribution is uniform, the pH value is 6.0-7.5, the sunlight is sufficient, the soil layer is deep, and the drainage is good.
Although the cassava is widely planted and the yield can be obtained, in order to obtain high yield, high quality and high efficiency, a good environment for the growth of the cassava must be created according to the fertility characteristics of the cassava. As the cassava is root crops and deep root crops, the root crops generally have the depth of more than 25-30 cm. Therefore, the soil preparation must be deep and loose to facilitate the growth of the root tuber. Deep ploughing is generally required to be 25-30 cm, and the depth cannot be less than 20 cm. In fact, it is not easy to do so, so that the machine tillage, even large-scale machine tillage, can meet the requirements, especially in mountainous regions. The water can be recovered by shallow hilling for many times, but the water cannot be accumulated for too long time by paying attention to water drainage.
However, in the cassava production area in China, the traditional habit of cassava seed stem preservation is still used, the open-air storage method, the ditch storage method, the cellar storage method and the like are mainly adopted, relatively strict storage conditions and management measures are needed, and the storage effect is not ideal. If the individual year with severe frost is met, a large number of seed stems are frozen to death, dried or rotten, and good seed gaps are severe, so that the healthy development of the cassava industry is greatly restricted.
In order to solve the problems, a research institute in certain city of Fujian province of China provides a cassava seed stem field seed reserving and preserving technology, and cassava seed stems are permitted to grow in the field under natural conditions in the south of Min in winter. The specific method comprises the following steps: cleaning garden, removing impurities, hilling, preventing collapse, controlling axillary buds, preparing soil, digging holes, cutting seeds and planting. Through experimental observation and data determination, the net weight rate of the seed stems stored in the field reaches 98.13 percent, which is 29.17 percent higher than the net weight rate (68.96 percent) stored in a room, the seedlings begin to emerge after 10 days of planting in the field, the rate of emergence reaches 97.33 percent after 20 days, which is 51.55 percent higher than the common indoor storage mode, and the seedlings are leveled 15 days earlier and have regular and vigorous growth vigor. The cassava seed stems are reserved and stored in the field, the utilization rate and the emergence rate of the seed stems can be greatly improved, seedlings are aligned in advance, and the growth is promoted, so that the technical measure is simple, convenient, practical and effective, and is worthy of popularization and application.
However, in the prior art, in the process of reserving seeds and preserving cassava seed stems in the field, a protection device is lacked, and the cassava seed stems are easy to bite by insects in soil, and in addition, in some cold areas in winter, the heat preservation effect only depending on the soil is far from insufficient, so that the cassava seed stems are very easy to freeze.
