Seed prices and planting methods

Broussonetia papyrifera, also known as Broussonetia papyrifera, Broussonetia papyrifera and so on, is a deciduous tree plant of Moraceae with high cultivation value. Its leaves are very good pig feed, phloem fiber is an advanced raw material for papermaking, roots and seeds can be used as medicine, and tree sap can treat skin diseases. let's take a look at the seed price and planting method of Broussonetia papyrifera.

How much is the seed of Broussonetia papyrifera?

The price of Broussonetia papyrifera seeds is about 60,100 yuan per jin, but it varies greatly due to different seed quality, variety, producing area, market and so on.

Seeds or cuttings are often used in production. In order to overcome a large number of fruit drop of female plants at maturity and affect environmental hygiene, male plants can be used as scions to cultivate grafted seedlings.
