Balanced nutrient fertilizer for tomato cultivation

Abstract

The invention discloses a balanced nutrient fertilizer for tomato cultivation. The balanced nutrient fertilizer is prepared from the following components: KNO3 / CO(NH2)2 / (NH4)2SO4, 5Ca(NO3)2NH4NO3.10H2O / Ca (NO3)2.4H2O, KH2PO4 / Ca (H2PO4)2, KCl / K2SO4, MgSO4.7H2O / MgSO4.H2O, FeSO4.7H2O, and EDTA-Na. Experiments prove that the preparation method has the advantages that compared with a conventional fertilization method (organic fertilizer + compound fertilizer + urea), the application method is simple and convenient, the fertilizing amount is small, nitrogen and phosphorus are greatly reduced, plantsgrow robustly, bacterial diseases are resisted, the pesticide spraying frequency is reduced, the pesticide cost and labor cost are reduced, the yield per mu can be increased by about 10%, the qualityand taste of tomatoes are improved, the original flavor of tomato is recovered, and meanwhile the storage period of tomatoes is prolonged.

Description

technical field [0001] The invention belongs to the field of fertilizer and nutrient solution production, in particular to a tomato balanced nutrient fertilizer used for tomato cultivation. Background technique [0002] Tomato is one of the most important vegetable crops in our country. Its planting range is all over China. According to statistics, my country's tomato planting area reaches 17 million mu, and its total output reaches about 67 million tons, accounting for 5% of my country's vegetable planting area and 8.3% of its output. It is one of the important vegetable crops. However, due to the excessive use of chemical fertilizers in recent years, the soil fertility in the main vegetable-growing areas has seriously declined, soil compaction, serious soil salinization, and a series of side effects such as river water and groundwater pollution have emerged. Seriously affected the yield and quality of vegetable crops. Pests and diseases are getting worse, spraying pesti...

Problems solved by technology

However, due to the excessive use of chemical fertilizers in recent years, the soil fertility in the main vegetable-growing areas has seriously declined, soil compaction, soil salinization are serious, and a series of side effects such as river water and groundwater pollution have emerged.

Seriously affected the yield and quality of vegetable crops

Pests and diseases are getting worse, spraying pesticides has become the norm, and pesticide residues have exceeded the standard, causing food safety issues, etc.

[0003] Tomato is a fruit and vegetable crop with super growth potential. It has strong adaptability and stress resistance to the environment. However, due to the long-term excessive use of chemical fertilizers, the normal production of tomato is threatened.
