Hotbed for grape nursery stock root promotion

Abstract

The invention discloses a hotbed for grape nursery stock root promotion. The hotbed comprises a bed pit and a heating device. The bottom of the bed pit is provided with a water pipe which is laid. Theupper part of the water pipe is provided with a matrix. The hot water pipe of the water pipe is connected with the water outlet of the heating device. The water outlet pipe is connected with one water inlet of the heating device. The water outlet pipe of the water pipe is provided with a water pump. According to the hotbed for grape nursery stock root promotion, water circulation is used for realizing temperature controlling, thereby realizing controllable temperature. The hotbed has advantages of low construction cost, low use cost, wide application range and easy popularization.

Description

technical field [0001] The invention belongs to the technical field of grape planting, and in particular relates to a hotbed for promoting roots of grape seedlings. Background technique [0002] The germination of grape bud eyes generally requires a temperature of about 10°, while the temperature required for rooting is higher, and the rooting is fastest at 25-28°. In the spring of March to April in northern my country, the temperature rises rapidly, while the low temperature rises slowly. Open field cuttings often germinate first and then take root. The time difference between germination and rooting is more than 20 days. The nutrient supply is not enough and withers, which seriously affects the survival rate of cuttings. Therefore, rooting treatment must be carried out before cuttings. [0003] The commonly used methods of root stimulation in production are chemical agent treatment root stimulation, electric heating root stimulation, brewing hotbed root stimulation, and f...

Problems solved by technology

Among them, hotbed root stimulation has the advantages of simple operation, strong and durable, and is widely used. However, electric root stimulation requires continuous power supply for about 15 days, which consumes a lot of power and is expensive, so it is not suitable for small-scale rural market promotion.

Although the cost of traditional fire pit rooting is low, the temperature is not easy to control, and it is easy to cause high temperature, which is not conducive to rooting and causes rooting failure.

Another kind of brewing hotbed to promote root is the principle of using horse manure to ferment and generate heat, but the fermentation takes a long time, the time cost is high, the temperature is not easy to control, and it is not easy to promote
