Before the plant sprouts, spray the mixture of stone sulfur mixture 3-5 degrees and pentachlorophenol sodium 200-300 times to kill the pathogen. After the first leaf unfolds, it should be sprayed every 10 days. Once a live worm is found, it can be wiped off with a dishcloth.

Planting methods and matters needing attention of raisins

The main results are as follows: 1. the survival rate of spring planting is higher than that of autumn planting, and the planting period is from early to late February.

Before planting, it is necessary to apply sufficient base fertilizer, such as: more than 40 kg of rotten organic fertilizer per plant, 3 kg of superphosphate, 0.2 kg of potassium sulfate and so on.

5. Matters needing attention: in cultivation, attention should be paid to the application of phosphorus and potassium micro-fertilizer and organic fertilizer, and the amount of nitrogen fertilizer should be controlled to prevent the fruit from low sugar content, low Lignification of fruit stalk and decrease of storage tolerance. Stop irrigation 10-15 days before harvest, and harvest should be postponed in case of rain.

The origin of raisins

Raisins are native to California, USA, with an annual average temperature of more than 18 ℃. However, Fuzhou in Fujian Province and Qingdao in Shandong Province have been successfully introduced, indicating that the temperature in most parts of China is adapted to the growth of raisins.
