Re: veterans struggle with pests and diseases for 18 years

After the drug spray ended, Peng Hongjing arrived at the defense area of Bai Bibi village in the town of Jing Zi, the town of Jing Zi, and found that the Masson Pine base was badly affected, and the pine needle was almost eaten by the caterpillar. So he quickly contacted the flight prevention team and arranged for another two sorties in the Bai Bi Village defence area. Due to geological constraints, Tsing Zi began to spread pine seeds on planes in the 80s of last century. Over the past 30 years, these mountains have been filled with pine trees. Large areas of pure forests are very vulnerable to diseases and insect pests.

Peng Hongjing is looking at the caterpillar's disaster. There are two cocoons and three caterpillars on a branch. Peng Hongjing was very worried. After the prevention and cure, the caterpillar would eat the pine needles and die, but the cocoon should be arranged to pick up the insects, so as to prevent any insect pests from happening again.

one morning, Peng Hongjing had only a cup of eight treasure porridge to fill the hunger.
