“七○二”是核酸降解物,其主要成份为核苷酸等,参与植物细胞的核酸代谢。核酸对动植物的生长、繁殖、遗传、变异起着决定作用。核酸代谢旺盛,促进了植物细胞的分裂繁殖,植物的个体生育就更完善。主要表现为促进根系生长,增强根系吸收能力,增蘖增穗,增粒增重。 鱼精“七○二”的成本低,使用方便,效果较稳定。经广东、浙江、上海、江苏等省市五年来的实践证明, “Seventy-two” is a nucleic acid degradation products, the main components of nucleotides, involved in plant cell nucleic acid metabolism. Nucleic acids play a decisive role in the growth, reproduction, genetics and mutation of plants and animals. Nucleic acid metabolism, and promote the division of plant cells, plants, individual childbearing even more perfect. Mainly to promote root growth, increase root absorption capacity, increase tillering ear, grain weight gain. Fish “702” low cost, easy to use, the effect is more stable. After five years of practice in Guangdong, Zhejiang, Shanghai, Jiangsu and other provinces and municipalities,
