Paris polyphylla seedling cultivation method capable of avoiding paris polyphylla radicle damage

Abstract

Provided is a paris polyphylla seedling cultivation method capable of avoiding paris polyphylla radicle damage. The method comprises the step of adopting a paris polyphylla drawer type seedling culture box to perform radicle germination culture of paris polyphylla seeds and seedbed seeding. A soil structure of the culture box comprises a thin sand layer, a soil layer I, a sand layer I, a seed layer, a sand layer II and a soil layer II. The seedbed seeding comprises the steps that the culture box is placed on a seedbed soil moisture surface, a movable base plate is pulled out, each sand layer and soil layer and growing seeds on the movable base plate entirely fall to the surface of a seedbed, and a frame is taken out. The seeds are not contacted in the whole process, the damage to radicle and root hair growing on the radicle is avoided, rapid growth of the seedlings is promoted, the seedling culture time is shortened, and the emergency rate is greatly improved. Meanwhile, labor force investment and complex operation are reduced, labor intensity is alleviated, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of authentic Chinese medicinal plant seedling breeding, in particular to a cultivation method for avoiding damage to the radicle of the dianthus dianthus and the immature root hairs attached to the radicle when cultivating the seedlings of the dianthus dianthus. 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 mat...

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
