Problems solved by technology

[0002] In the process of traditional tomato planting, due to continuous planting, continuous cropping obstacles are particularly serious, resulting in many diseases, and a large amount of pesticides have to be sprayed to prevent pests and diseases; in addition, due to the long-term use of chemical fertilizers in traditional tomato planting methods, planting tomatoes The hardening of the land, the decline in fertility and other reasons lead to a serious decline in the yield of tomatoes. What is more serious is that the quality of tomatoes is not guaranteed due to the application of a large amount of chemical fertilizers and pesticides.
At the same time, the traditional tomato production has the characteristics of cumbersome production management

Example Embodiment

[0014] Explanation of terms involved in this application:

[0015] EDTA iron: EDTA is ethylenediaminetetraacetic acid, it has a chelating effect on metal ions, and it chelates iron ions to become EDTA iron.

[0016] The present invention will be further described in detail below in conjunction with specific examples, but the embodiments of the present invention are not limited thereto.

[0017] In order to screen the tomato cultivation nutrient solution suitable for tomato coconut bran substrate, two kinds of nutrient solutions were tested, namely the Yamazaki nutrient solution developed by Yamazaki Kenza in Japan and the PBG nutrient solution of the Dutch Greenhouse Crop Research Institute. The effects of different nutrient solution formulations on coconut were analyzed and compared. Changes in the electrical conductivity (EC) and pH of the bran substrate will affect the growth, yield and quality of tomatoes. The results showed that the rhizosphere EC value of Yamazaki nutrient sol...

Abstract

The invention relates to a tomato cultivation nutrient solution based on coconut bran substrate, which includes: a vegetative growth stage nutrient solution, a reproductive stage nutrient solution, and a microelement nutrient solution; wherein the vegetative growth stage nutrient solution comprises Ca(NO3)2.4H2O, KNO3, NH4H2PO4, K2SO4 and MgSO4.7H2O; the reproductive stage nutrient solution comprises Ca(NO3)2.4H2O, KNO3, NH4H2PO4, K2SO4 and MgSO4.7H2O; and the microelement nutrient solution comprises EDTA-Fe, H3BO3, MnSO4.H2O, ZnSO4.7H2O, CuSO4.5H2O, (NH4)6Mo7O24.4H2O. The tomato cultivation nutrient solution has a proper electrical conductivity during the reproductive stage of tomatoes, so that sufficient nutrients are supplied to tomatoes. The pH value of the nutrient solution is suitable for growth of tomatoes.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a tomato cultivation nutrient solution based on a coconut bran substrate. Background technique [0002] In the process of traditional tomato planting, due to continuous planting, continuous cropping obstacles are particularly serious, resulting in many diseases, and a large amount of pesticides have to be sprayed to prevent pests and diseases; in addition, due to the long-term use of chemical fertilizers in traditional tomato planting methods, planting tomatoes The hardening of the land and the decline in fertility have led to a serious decline in the yield of tomatoes. What is more serious is that the quality of tomatoes is not guaranteed due to the application of a large amount of chemical fertilizers and pesticides. At the same time, the traditional tomato production has the characteristics of cumbersome production management, heavy labor, low production efficienc...
