Cabbage is one of the important vegetable crops in China, with its short growth cycle and high yield, and is deeply loved by farmers. However, in order to grow high-quality, high-yield cabbage, proper fertilization is key. This article will give you a detailed introduction to the characteristics and use of special fertilizers for cabbage to help you achieve high quality and high yield of cabbage.
1. Cabbage growth needs and fertilizer selection.
Cabbage grows quickly and has a high demand for nutrients. It mainly requires macroelements such as nitrogen, phosphorus, and potassium, as well as medium elements such as calcium, magnesium, and sulfur. In order to meet the growth needs of cabbage, we should choose special fertilizers with comprehensive nutrients and reasonable proportions.
Second, the characteristics of special fertilizer for cabbage.
Nutrients are completeAccording to the growth needs of cabbage, the special fertilizer for cabbage scientifically proportions a large number of elements such as nitrogen, phosphorus, potassium, etc., and adds an appropriate amount of medium and trace elements to ensure that all kinds of nutrients required for the growth of cabbage can be met.
Targeted: Special fertilizer is developed according to the growth characteristics and fertilizer requirements of cabbage, which can better promote the growth and development of cabbage, and improve yield and quality.
Easy to absorb and utilize: The special fertilizer adopts advanced production technology, so that the nutrients in the fertilizer are more easily absorbed and utilized by cabbage, reducing nutrient loss and waste.
Third, the use of special fertilizer for cabbage.
Basal fertilizer application: Before sowing or transplanting, spread special fertilizer evenly on the surface of the soil, and then plough into the soil. The amount of basal fertilizer should be determined according to soil fertility and target yield, generally 30-50 kg per mu.
Top dressing application: During the growth period of cabbage, top dressing should be carried out in a timely manner according to the growth situation and soil nutrient status. Generally, special fertilizer can be applied once in the rosette stage and the core stage, and 10-15 kg per mu can be applied each time.
Foliar sprays: In the middle and late stages of cabbage growth, foliar sprays can be used to supplement nutrients. After diluting the special fertilizer in a certain proportion, it is evenly sprayed on the leaf surface of cabbage with a sprayer, which can quickly replenish nutrients and improve the stress resistance and quality of cabbage.
4. Precautions.
Fertilize in moderation: Excessive fertilization is not only a waste of resources, but can also have a negative impact on the environment and cabbage growth. Therefore, the amount of fertilization should be reasonably determined according to soil fertility and target yield.
Deep mulching: In order to avoid the volatilization and loss of fertilizer, the soil should be covered in time after fertilization. The depth of the covering soil should generally reach 5-10 cm.
Avoid direct contact with seeds: When applying basal fertilizer, attention should be paid to avoid direct contact between fertilizer and seeds, so as not to affect seed germination and seedling growth.
Keep the soil moist: After fertilization, it should be watered in time to keep the soil moist, which is conducive to the dissolution of fertilizer and the absorption of cabbage.
By understanding the growth needs of cabbage and the characteristics and use methods of special fertilizers, we can carry out fertilization management more scientifically and help cabbage achieve high quality and high yield. Hopefully, this article will provide you with useful help and guidance for your cabbage planting.
