Lessons to Remember After Losing Out by Not Applying Organic Fertilizer to Jujube Trees
This year, the selling prices of jujubes varied greatly. The price differences were mainly due to differences in sweetness and crispness, and apart from varietal characteristics, the main reason for the differences in sweetness and crispness was the different types of fertilizer applied. Currently, it is the second root development period for jujube trees. The first root growth peak occurs from late May to early June after new shoots stop growing, and the second root growth peak occurs from after fruit harvest to early November.

Ten observations for silkworm disease prevention and control: remember these ten key points when raising silkworms
1. Observe the development of the colony. When the ants are collected, the hatching is uneven, the ant silkworms are uneven in size, with big heads and small tails, spin a lot of silk, and crawl around the rearing seat, indicating a weak constitution. During rearing, touch the silkworm body with your hand or lift the silkworm up; if the silkworm contracts and resists, it is healthy; if it has no reaction, it indicates a weak constitution. In the large silkworm stage, touch the silkworm body flatly with the back of your hand; if it feels cold, it is a healthy silkworm; if it feels damp and hot, it indicates that the constitution is not strong. 2. Observe the posture before and after molting. When a healthy silkworm is about to molt, its head and thorax are raised, and molting is uniform.
