Fertilization methods for High yield of Tomato

Tomato is a common vegetable in our country. Fertilization is a necessary work in the process of planting tomato. However, fertilization has certain skills. Too much or too little fertilization will lead to partial application or lack of nutrients in tomatoes. Directly affect the growth of tomatoes, reduce yield, resulting in poor quality. How should tomatoes be fertilized? The following small series brings you the high-yield fertilization method of tomatoes. Let's take a look at it together.

1. Characteristics of fertilizer requirements

Tomato growth of nitrogen and potassium demand, phosphorus demand is not large, like to grow in nutrient-rich soil. The demand for nitrogen rises sharply before tomatoes set, but drops after successful fruit set, requiring large amounts of potassium instead. Therefore, in the process of planting, we should adjust the fertilizer use reasonably according to each growth stage of tomatoes according to the characteristics of tomato fertilizer demand. Avoid the physiological deficiency of tomatoes caused by improper fertilization, which affects the yield and quality.

2. Apply basal fertilizer

Before planting tomatoes, we should not only do a good job in soil preparation, but also apply sufficient base fertilizer when soil preparation, and the base fertilizer is mainly decomposed farm manure. Sufficient base fertilizer can ensure that tomatoes have sufficient nutrition throughout the growth period, and improve the application of organic fertilizer can also effectively improve the soil structure, increase the particulate matter in the soil, improve the soil softness, ensure the respiration of tomato roots, and create a good environment for root growth and development. Promote root robust growth and seedling, enhance plant resistance.

3. Timely topdressing

In general, in the case of sufficient base fertilizer, tomato planting to the results of this period of time can not be topdressing. When the first fruits are gradually expanded, topdressing should be started, combined with watering. And then in the follow-up fruit expansion should do a good job of topdressing work, to improve the application of potassium fertilizer, to ensure the normal growth and development of tomatoes. It can also be combined with appropriate biological fertilizer to promote the extension and development of roots and reduce the number of harmful bacteria. Prevent root diseases and various physiological problems, improve tomato yield.

4. Spray foliar fertilizer

Reasonable foliar fertilizer can prevent many problems of tomatoes, as well as the effect of topdressing outside the roots. Some problems caused by lack of elements can be supplemented by spraying foliar fertilizer. Appropriate spraying of leaf fertilizer can promote flower bud differentiation, enhance stress resistance of tomato, prevent premature aging of plants and a series of effects. And different foliar fertilizers can prevent different physiological diseases, such as borax can prevent tomato Li Ruiguo, nucleotide can prevent yellow leaves and so on. Therefore, foliar fertilizer application is also very important in tomato fertilization.

The above is a simple introduction to the high-yield fertilization method of tomatoes. Although tomatoes have strong growth ability, high yield and simple planting, they also need to do a good job in planting management. Especially fertilization, fertilizer application is to supplement the lack of nutrients tomatoes, if not properly fertilized, tomatoes will lead to insufficient nutrition or lack of certain elements, affecting the growth of tomatoes, yield decline, quality reduction.
