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...

Embodiment 1

[0120] The experiment was carried out in Zhejiang area, using the Millennium variety, with three repetitions. Under the premise of not using the base fertilizer, the a) fertilizer was applied as a water-soluble fertilizer, and the fertilizer was applied every 5 to 15 days after planting, and the amount of fertilizer applied was 1 to 10 times. 5kg / mu; the total amount of fertilizer applied for 6 months in one season is 70kg / mu. The control treatment is conventional fertilization by farmers, using 1 ton / mu of organic fertilizer (base fertilizer), 100kg / mu of compound fertilizer, 50kg / mu of urea, 1 ton / mu of organic fertilizer and 150kg / mu of chemical fertilizer in total.

[0121] The specific topdressing method of tomato balanced nutrient fertilizer: add the above a) fertilizer according to the ratio of 1 to 5 kg per ton of water to fully dissolve the fertilizer, and spray it directly on the tomato cultivation bed through sprinkler irrigation or micro-spray equipment, and the cul...
