Alias ​​breeding new method

Alisma, a perennial marsh plant, should be selected fertile, flat, easy irrigation and drainage of Putian, Pak Pak Tin or paddy fields.

At the time of site preparation, pig manure was first applied to the soil. Drain water into the field before transplanting. The ploughshare was twice, the mud was smashed, and the ground was flat. Open ditch around the field, favorable drainage.

Because the seeds are very small, some grass ash can be mixed with new high-fat membranes and sprinkled into the surface of the pods to repel insects in the ground, isolate the virus infection, strengthen the respiratory intensity, and increase the seed germination rate. Then tap it gently with a broom so that the seeds and soil are well pressed.

After sowing, the surface of the soil is sprayed with 600-times new high-fat film 600, which can protect the water from evaporation, sun protection, drought resistance, heat preservation and anti-freeze, anti-soil compaction, suffocation and isolation of pests and diseases, and improve the emergence rate. Shed shading, covered with a curtain during the day and rolled up at night, which is conducive to the growth of seedlings.

The transplant period is dominated by the age of the ape. This has less stems and higher yields. It is better to be short and strong. Raise the seedlings with your fingers when raising the seedlings. With the planting. (Dao Ye, Department of Pharmaceutical Engineering, Yangling Vocational and Technical College)
