Description
Technical Field
The invention relates to a temperature-increasing and heat-preserving cultivation method for bamboo shoots of scattered bamboo in winter, and belongs to the technical field of agricultural planting.
Background
The phyllostachys praecox in the scattered bamboo is a main bamboo cultivation variety for bamboo shoots in China, the planting technology is completely mature at present, and the planting area in China is large. In order to solve the practical problems that spring bamboo shoots are on the market in a centralized way, the market is difficult to digest, the economic benefit is low, the enthusiasm of bamboo farmers is damaged, people have been actively explored for years for spring bamboo shoots to grow in winter, the winter bamboo shoots are required to grow out, namely, buds on bamboo shoots grow in winter and break the soil, and the key point is to solve the technical problems of surface temperature increase and space heat preservation of bamboo forests in winter.
At present, the temperature increasing method for bamboo shoots of phyllostachys praecox in winter mainly comprises five methods, namely a covering material covering fermentation temperature increasing technology, a covering material and mulching film covering temperature increasing technology, a covering material temperature increasing technology, a plastic barrel covering technology, a covering material and embedded electric heating pipe temperature increasing technology and a greenhouse heat preservation planting technology.
The above warming techniques have the following disadvantages, which are now described as follows:
1) covering fermentation temperature increasing technology for covering
The technology is mainly applied at present, and has the defects of shortage of covering material sources, rising purchasing cost, high labor intensity, more required labor force, high labor cost, more procedures, long covering time, high investment and poor control of covering time and covering effect. Generally, the bamboo shoots are covered by a plurality of layers of rice chaff, bamboo leaves, straws, wheat straws, sawdust, stable manure and the like, the thickness is 0.5-1 m, the using amount is large, the heat is only once, the heat cannot be recycled, underground whips are easy to rot due to multiple covering, the pH value of soil is changed, bamboo forests are damaged, and the freshness and tenderness degree of the bamboo shoots is also reduced. In addition, the winter bamboo shoots are under the covering, the harvesting is difficult to find, bamboo shoot stem dirt needs to be removed after the harvesting, and meanwhile, the color tone of the covered winter bamboo shoots is inconsistent with that of the spring bamboo shoots, so that consumers often think that the winter bamboo shoots contain chemical components.
2) Covering and plastic film covering temperature increasing technology
The technology reduces the thickness and the dosage of the covering, increases the mulching film covering on the covering, and compared with the simple covering fermentation temperature increasing technology, the technology needs to increase the procedures of film uncovering, film covering and the like in the links of harvesting, fertilizer water application and the like, in addition, the bamboo shoot emergence time is not easy to grasp, the bamboo shoots in winter can easily penetrate through the mulching film after growing out, the continuous heat preservation during the bamboo shoot emergence period is not facilitated, the covering time is long, the covering can not be recycled, and the whole effect is poor.
3) Technology for covering plastic barrel by covering object with heating
Compared with the technology of covering and plastic film mulching warming, the technology has the problems that the covering source is short, the purchase cost is increased, the heat preservation effect is poor, the covering time is long, the covering cannot be recycled, the plastic barrel covering has requirements on the gradient of a bamboo forest, the covering area of the plastic barrel accounts for 50% -80% of the area of the covering, the covering is wasted, the yield of winter bamboo shoots is low, the procedures of barrel moving, barrel covering and the like need to be added in links of management, harvesting, fertilizer water application and the like, in addition, the manual observation is frequent, and the timing of bamboo shoot emergence is not easy to grasp.
4) Covering and embedded electric heating tube heating technology
The biggest problems of the technology are that the electric heating pipe is low in heat efficiency, serious in heat dissipation loss, fast in local temperature rise, high in energy consumption, poor in heat preservation effect, short in cover source, high in purchase cost, and easy to damage the electric heating pipe when the cover is removed and bamboo shoots are picked.
5) Greenhouse heat-preservation planting technology
The technology adopts a mode of covering the whole plants of the greenhouse on the bamboo forest, is difficult to popularize and apply due to the following defects, and is mainly in a scientific research stage at present: bamboo for bamboo shoots is tall and big, grows fast, and the requirements for landform and landform site selection, traffic conditions, materials, strength and the like are high when the greenhouse is built, so that the manufacturing cost is high, and the implementation is difficult. Meanwhile, the greenhouse covered by the whole plant is difficult to meet the natural conditions of illumination, ventilation and the like required by the growth of bamboo shoots, the greenhouse is tall and big, and the temperature, humidity and gas are difficult to regulate. Under the condition of high energy consumption, the problem of low surface temperature of the bamboo forest is not solved. In the greenhouse, a covering is often needed to be supplemented to the bamboo forest ground to generate the heat preservation effect.
In conclusion, in the field of temperature increase and heat preservation of spring bamboo shoots in winter, new technology is urgently needed.
