At the beginning of this year, China Aerospace Breeding Center sent invitations to nine agricultural teaching and research institutions that have made certain achievements in this field, among which Loudi Mechanical and Electrical Engineering School (formerly Loudi Agricultural Machinery School) was among them. The total amount of seeds carried this time is 288 1g (Taiwan Province Academy of Agricultural Sciences carries 500g), and the carrying cost of each 1g seed is 600 yuan. Loudi sent 1.3g, including more than 60 high-quality rice seeds and more than 300 cockscomb seeds. These rice seeds were selected by Fang Jinliang, an agricultural expert, from the excellent varieties cultivated. Two-thirds of the same ear of rice was carried to the sky, and one-third was left on the ground for comparative experiments.
