Two-stage cultivation method of ophiopogon japonicus

By adopting a two-stage cultivation method in Ophiopogon japonicus planting, rice and Ophiopogon japonicus are planted in separate areas to achieve crop rotation between water and dryland crops. This solves the problems of competition between medicinal and grain crops for land and pests and diseases in traditional planting, and improves the yield and economic benefits of Ophiopogon japonicus and rice.

AI Technical Summary

Technical Problem

Traditional planting methods for Ophiopogon japonicus involve competition between medicinal and food crops for land. Continuous dryland farming combined with continuous cropping leads to an increase in pests and diseases, and weeding costs are high while yields are low.

Method used

A two-stage cultivation method is adopted, dividing the planting field into paddy fields and lilyturf seedling fields, and planting rice and lilyturf together. After the rice is harvested, lilyturf seedlings are planted. A crop rotation system is adopted, fertilizers are applied rationally, planting density and timing are controlled, and reliance on manual weeding is reduced.

Benefits of technology

This method enabled crop rotation of Ophiopogon japonicus and rice in the same field within a year, which increased the yield of Ophiopogon japonicus and the output of rice, reduced the cost of pest and disease management, and significantly improved various growth indicators and net income of Ophiopogon japonicus.

Abstract

This invention provides a two-stage cultivation method for Ophiopogon japonicus, belonging to the field of Ophiopogon japonicus planting technology. The two-stage cultivation method includes the following steps: dividing the planting field into a paddy field and an Ophiopogon japonicus seedling field, and planting rice and Ophiopogon japonicus seedlings together in the paddy field and the Ophiopogon japonicus seedling field respectively; after the rice harvest, planting the Ophiopogon japonicus seedlings in the planting field. This invention enables crop rotation of Ophiopogon japonicus and rice within the same planting field within one year, ensuring Ophiopogon japonicus production while increasing rice production for one season, solving the problem of competition for land between medicinal and grain crops, thus protecting both medicinal and grain crops. Compared with traditional cultivation methods, the cultivation method of this invention significantly improves indicators such as leaf length, root number, number of fruit roots per plant, fresh weight of stems and leaves, fresh weight of roots, fresh weight of Ophiopogon japonicus per plant, and yield per acre. The two-stage cultivation method of this invention results in high Ophiopogon japonicus yield and low cost, while also increasing rice production. Therefore, the net benefit of the two-stage cultivation method of this invention is far higher than that of traditional cultivation methods.
