Skillfully storing peaches to prolong the fresh and crisp period
Timely pre-cooling and anti-softening due to the high temperature during harvest, especially the middle and late ripening varieties, if the peach is not precooled in time, the peach will soon soften and decay. Therefore, the peach should be precooled below 4 ℃ as soon as possible after harvest, generally using cold air cooling and water cooling. The water cooling rate is fast. The peach with a diameter of 7.6cm can be cooled in 1.6℃ water for 30 minutes, and its temperature can be reduced from 32 ℃ to 4 ℃. After water cooling, the peach can be dried and then packaged.

Soil Management of Jujube Orchard
Ploughing, weeding, loosening soil and preserving soil moisture: the newly planted jujube orchard made a 1m wide tree row after planting, and then widened year by year with the expansion of the tree crown. The pure jujube orchard with high density can generally be intercropped with some dwarf legumes or melons and vegetables three years before planting, and the jujube orchard with jujube grain intercropping can be used for long-term intercropping of crops. In this way, the scope of jujube soil management in the first three years is mainly in the range of tree rows, and the future soil management will be carried out in the whole garden. The first problem in soil management is to eradicate weeds because of the growth of weeds.
