Introduction of Fritillaria thunbergii

Zhejiang shellfish basic information: Zhejiang shellfish began to give birth in May, like plenty of sunshine, cool and humid climate, afraid of high temperature, drought and stagnant water. Fritillaria thunbergii has the characteristics of self-incompatibility, low natural seed setting rate, and generally does not use seeds to propagate. It is propagated with fresh seed bulbs, planted in October of the Gregorian calendar, and dug in June of the following year. The yield of dry products per mu is about 200 kg in normal years.

It uses about 300 kilograms of fresh mother seed per mu, and there are two germs in the mother seed. By the time it was harvested in the second year, the Fritillaria planted in the first year had been drained by two germs, leaving only two new Fritillaria. So planting one mother seed and producing two children, that is to say, planting one mother seed, the yield doubled in the second year, with a harvest of about 600 kilograms. Fresh products need 3kg or 3.2kg to process 1kg dry products. The production cost is mainly planting balls, which usually takes 20 man-hours, plus other fertilizers are about 25 yuan according to the current price level. Lower than this level will affect farmers' enthusiasm for production.
