Out-of-season cultivation method of fresh gingers

Abstract

The invention relates to an out-of-season cultivation method of fresh gingers. The method comprises the steps that A, a film tunnel is set up, wherein atomization and spray irrigation equipment is installed inside the tunnel and an atomizer is installed at the top inside the tunnel; B, the middle and the two sides inside the tunnel in the longitudinal direction are respectively provided with a water collecting ditch, and net pipes are embedded in the lower portions of the water collecting ditches, wherein the net pipes are used for collecting and temporarily storing warm water leaking from the water collecting ditches, and enabling the warm water to well permeate towards the sand layers and the underground, and meanwhile heat energy is transmitted to the soil layers and the underground along with the permeation of the warm water; C, ridging cultivation is carried out, wherein high and low ridges are adopted for planting, low-density shallow layers are adopted for planting on the low ridges, and high-density deep layers are adopted for planting on the high ridges; D, planting and harvesting are carried out, wherein the fresh gingers start to be planted when seed gingers are harvested on other places in November of Gregorian calendar, the planted fresh gingers on the high ridges can be harvested and dug before and after the Spring Festival, young gingers and old gingers appear on the market at the same time, and the planted fresh gingers on the main planting rows of the low ridges can be harvested and dug successively after the Tomb-sweeping Day of the next year to October of Gregorian calendar. According to the method, the time when the fresh gingers appear on the market is the best-selling period (in summer and autumn), the fresh gingers can directly appear on the market after being harvested, storage equipment and storage troubles are reduced, and natural risk and market risk are avoided completely.

Description

technical field [0001] The invention relates to an off-season cultivation method of ginger. Background technique [0002] Due to the long germination period of ginger seedlings, about three months. The root regeneration ability is weak and it is difficult to transplant. The temperature range suitable for growth is also small (18-28) degrees Celsius. Especially the seedling stage requires (20-26) degrees. If it is too low, it will grow too slowly, and if it is too high, it will easily become weak seedlings, which will seriously affect its yield and quality. Ginger goes dormant at 13 degrees Celsius, and ends all growth before it can only grow again. Below 10 degrees, it is easy to get frostbite or freeze to death. Using external heating is too wasteful of energy to make the cost unusable for actual production. [0003] Blowing hot air into the roof of the shed underground with a blower then makes the construction cost higher. However, in southern Hainan of my country, ...
