[0024] The preparation method of fermented manure is to add 3%-5% crop straw by volume to cow dung and / or sheep dung to adjust the carbon-nitrogen ratio, adjust the humidity to 55%-60% after mixing evenly, and ferment in large piles for 40-50 days;
[0025] The base fertilizer is a mixture of vermicompost and mixed controlled-release fertilizer in any proportion, wherein the slow-controlled release fertilizer includes the following elements in mass concentration: NO 3 - 400mg / L, NH 4 + 40mg / L, P 40mg / L, K 280mg / L, Ca 60mg / L, Mg 40mg / L, S40mg / L, Fe 3mg / L, B 0.5mg / L, Mn 0.5mg / L, Zn 0.05mg / L , Cu 0.02mg / L, Mo 0.01mg / L;
Embodiment 1
[0027] The sand culture cultivation method of high-sugar cherry tomato comprises the following steps:
[0028] 1) Put the seedling-growing substrate into the non-woven bag to 2 / 3, after pouring water thoroughly, sow tomato seeds on the seedling-raising substrate, cultivate, and grow tomato seedlings,
[0029] The seedling-raising substrate is a mixture of the following components in parts by weight: 40 parts of mushroom dregs, 20 parts of sand, 15 parts of fermented manure, and 20 parts of plant ash;
[0030] 2) Apply base fertilizer on the matrix sand layer of the cultivation tank in the greenhouse, plant the tomato seedlings together with the non-woven bag on the matrix sand layer, fasten the movable buckle of the non-woven bag mouth, and cultivate. The ambient temperature for cultivation is: The air temperature is controlled at 25°C from 10:00 to 14:00 every day, and 22°C from 14:00 to 10:00 the next day. The temperature at the depth of the substrate sand layer is 5-10cm at...
