Embodiment 1

[0037] Embodiment 1: (the optimum formula of screening nutrient solution with Chinese rose as material)

[0038] (1) configure the nutrient solution, the content of the compound in every liter of water is calculated in mg / L, and its composition and proportioning ratio are shown in Table 1 below;

[0039] Table 1: Components and contents of five nutrient solutions

[0040]

[0041]

[0042] Note: No. 1 is the Dutch rock wool drip irrigation formula

[0043] (2) Perlite-peat composite matrix is ​​configured, and perlite and peat are mixed in a volume ratio of 1:1;

[0044] (3) Irrigation of the upper pot of the plant and the nutrient solution. First move the cutting seedlings of the annual 'Taohong Heping' rose into the cultivation container, then water the seedlings slowly for 7 days, and then water every 7 days, with 400mL per pot. See Table 2 for the implementation effect.

Abstract

The invention belongs to the field of nutrient medium for soilless culture and a method for making the nutrient medium. The medium comprises a solid part and a nutrient solution. The making method comprises the steps of: pulverizing cotton seed shells and coal cinders, placing into two fermenting tanks, adding the nutrient solution until the materials absorb saturatedly, coating and fermenting for 8-14m; adding 2-4kg of 70% dexon raw powder into the decomposed cotton seed shells and the coal cinders per ton, uniformly stirring and airing; mixing the decomposed cotton seed shells and the coal cinders according to the volume ratio of 3:1-12:1; mixing 25-35kg of cake fertilizer to the mixed medium per ton, adding urine until the saturate state, re-coating and re-fermenting for 5-7m to enable the pH of the nutrient medium to be 7.0-7.5 when the fermentation is stopped, finally, adding a proper amount of sulfur powder to adjust the pH of the nutrient medium to be 6.0-7.5 so as to adapt the requirements of different plants. The nutrient medium has rich nutrient, favorable permeability, water retention, fertilizer retention, convenient making and wide raw material sources, and is suitable for various flowers and vegetables growing.

Description

technical field [0001] The invention relates to a nutrient substrate for soilless cultivation and a manufacturing process thereof, which can be popularized as a cultivation substrate for cultivating flowers, organic vegetables, green vegetables and other plants, and belongs to the field of agricultural technology. technical background [0002] Soilless cultivation refers to the cultivation technique of using other media instead of soil and using nutrient solution. Soilless cultivation can effectively solve the problems in traditional soil cultivation such as secondary salinization of soil, difficult to control nutrition, and heavy production work, and can effectively provide nutrients needed for plant growth, saving land, water, fertilizer, pesticides, etc. resources, greatly improving the yield and quality of plants. Therefore, soilless cultivation technology has great advantages and has gradually become an important form of large-scale production of horticultural flowers....
