Drawer seedling growth box for Paris polyphylla var. yunnanensis

Abstract

A drawer seedling growth box for Paris polyphylla var. yunnanensis mainly comprises a rectangular frame and a rectangular moving bottom plate, an integrated channel is arranged in the lower portions of inner walls of three sides of the rectangular frame, a receiving hole is arranged in the lower portion of the other wall of the rectangular frame, and the moving bottom plate passes through the receiving hole into the channel of the rectangular frame so that the lower portion of the frame is sealed. A thin sand layer, soil layer I, sand layer I, a seed layer, sand layer II and a soil layer II are arranged on the surface of the moving bottom plate in the frame from bottom to top. Operations to use the box mainly include: seeding in the seed layer, placing the whole box on the moisture face of a seedbed after seeds germinate, drawing out the moving bottom plate to allow all the sand layers, the soil layers and growing seeds on the moving bottom plate onto the surface of the seedbed, and taking out the frame; there is no contact with the seeds during the whole process, damage of radicles and their fibers is avoided, quick growth of seedlings is promoted, seedling growth time is shortened, labor input is decreased, operations are repeated, labor intensity is reduced, and production cost is saved.

Description

technical field [0001] The invention relates to the technical field of seedling breeding of authentic Chinese medicinal plants, in particular to a seedling cultivation box of Dianzhonglou. Background technique [0002] Paris polyphyla Smith var. yunnanensis (Franch.) Hand-Mazz is a perennial herb of the genus Paris polyphyla in the family Liliaceae. The rhizome is strong, 30-80cm high, glabrous, often purple-red, with 1-3 membranous leaf sheaths covering the stem at the base. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain, cooling the liver and relieving convulsions. It is used to treat carbuncles, sore throats, snake bites, bruises, convulsions and convulsions. [0003] It takes 8 to 10 years from planting to harvesting and utilization of Dianzhonglou. In order to obtain more raw materials, Chinese patent medicine pharmaceutical companies have greatly increased their purchase price, and the purchase price has reached more ...

AI Technical Summary

Problems solved by technology

There is following defective in this mode of operation: one, when getting the seed that radicle germinates, very easily touches radicle and the root hair that is born on the radicle, causes damage to the root hair that is born on the radicle, causes immature root hair The damage of the radicle can easily lead to diapause of the radicle, and even cause the germinated radicle to cause disease due to injury and infection of bacteria; 2. In the process of spreading the radicle-germinated seeds on the seedbed, the work efficiency is low and the manpower input is large , the cost is relatively high. Third, special care must be taken in the process of sowing on the seedbed, otherwise the radicle of the seed is easily damaged; The immature root hairs on the root are damaged against the root hairs on the radicle again, which damages the radicle of the seed or touches the immature root hairs on the radicle, so that the germinated radicle needs a certain amount of recovery to grow after entering the soil. Start to grow normally, which prolongs the cycle of cultivating Chonglou seedlings and increases the investment cost
