Embodiment 1
[0016] A pepper soilless culture method (application powder oxamide) that improves vitamin C content and reduces nitrate content, its steps are as follows:
[0017] Mix cow dung, rapeseed cake and crushed rice straw according to the dry matter weight ratio of 5.4:2.8:1.8, add commercially available organic fertilizer starter, compost and ferment, and decompose and ferment at 50-65°C for about 20 days to obtain decomposed organic Fat. Mushroom dregs are discarded culture substrates after planting Flammulina velutipes, with a water content of about 10%; river sand is passed through a 10-mesh sieve before use; plant ash is carbonized from rice husks.
[0018] The above components are fully mixed according to mass percentage: 48% of decomposed organic fertilizer, 34% of mushroom residue, 10% of river sand, 3% of powdered oxamide, and 5% of plant ash to prepare a soilless culture substrate.
[0019] Fill the soilless culture substrate into the growth tank (30 meters long, 5 meters...
Embodiment 2
[0024] A pepper soilless culture method (application powder oxamide and optimized proportioning) that improves vitamin C content and reduces nitrate content, its steps are as follows:
[0025] Mix cow dung, rapeseed cake and crushed rice straw according to the dry matter weight ratio of 5.4:2.8:1.8, add commercially available organic fertilizer starter, compost and ferment, and decompose and ferment at 50-65°C for about 20 days to obtain decomposed organic Fat. Mushroom dregs are discarded culture substrates after planting Flammulina velutipes, with a water content of about 10%; river sand is passed through a 10-mesh sieve before use; plant ash is carbonized from rice husks.
[0026] The above components are fully mixed according to mass percentage: 45% of decomposed organic fertilizer, 35% of mushroom residue, 10% of river sand, 4% of powdered oxamide, and 6% of plant ash to prepare a soilless culture substrate.
[0027] Fill the soilless culture substrate into the growth ta...
Embodiment 3
[0032] A pepper soilless culture method (application granular oxamide) that improves vitamin C content and reduces nitrate content, its steps are as follows:
[0033] Mix cow dung, rapeseed cake and crushed rice straw according to the dry matter weight ratio of 5.4:2.8:1.8, add commercially available organic fertilizer starter, compost and ferment, and decompose and ferment at 50-65°C for about 20 days to obtain decomposed organic Fat.
[0034]The following components are mixed according to mass percentage: 48% of decomposed organic fertilizer, 36% of mushroom residue, 8% of river sand, 3% of oxamide solid particles with a diameter of 3-4mm, and 5% of plant ash to prepare a soilless culture substrate .
[0035] Fill the soilless culture substrate into the growth tank (30 meters long, 5 meters wide, and 0.5 meters deep), choose full, germinated Xinbianjiao No. 1 pepper seeds and sprinkle them into the cultivation substrate, and the sowing density is 20 grains / m 2 .
