Fruit growers of jujube trees know that jujube trees are also a particularly fertile crop. It uses a large amount of fertilizer and usually needs to be applied regularly throughout the year. What key points do you need to pay attention to in order to grow high-quality jujube trees? The following is a detailed explanation.
1. Apply more organic fertilizers
Organic fertilizer can be used as the main nutrient rich material for jujube trees, accounting for over 70% of the total amount of fertilization. The types of organic and nutrient rich materials include various livestock, poultry manure, human manure, green manure, compost, and plant ash. Organic materials rich in nutrients are full fertilizers, which not only include the main factors of nitrogen, phosphorus, and potassium required for the growth and development of jujube trees, but also contain various trace factors.
2. Moderate fertilization
During the year, jujube trees have a longer dormancy period and a shorter growth period, with most varieties having an annual adult period of 175-180 days. In addition to using organic fertilizers, jujube trees also use appropriate amounts of chemical fertilizers before growth to meet their nutritional needs for the normal growth of various organs. The main chemical fertilizers are urea, which uses superphosphate, ammonium phosphate, potassium dihydrogen phosphate, and potassium sulfate.
3. Spraying foliar fertilizer
During the growth period of jujube trees, based on the characteristics of nutrient rich materials in various organs of the tree, the nutrient rich materials are dissolved in an appropriate concentration. In calm or breezy weather, they are evenly sprayed on the tree crown to supplement the nutrients of the tree and meet the nutritional needs of jujube trees at different growth stages.
