Tomato cultivation nutrient solution based on coconut bran substrate

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...

[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, heavy labor, low production efficiency, high cost and poor benefit.

[0003] Nowadays, soilless cultivation techniques are mostly used. At present, Dutch PBG nutrient solution and Japanese Yamazaki nutrient solution are used more for soilless cultivation of tomatoes. However, the conductivity of Japanese Yamazaki nutrient solution is low in the later stage of plant growth, and the nutrient supply cannot meet the requirements. For the growth requirements of tomatoes, the pH value of the Dutch PBG nutrient solution is relatively low, about 4.7-6.9, and the most suitable pH value for tomato growth is a weak acid environment with a pH value of 5.5-6.5

Therefore, these two culture solutions are not conducive to the rapid growth and fruiting of tomato
