Abstract

The invention discloses a nutrient formula for soilless culture of roses. The nutrient formula comprises the following components in parts by weight: 13-16.5 parts of sodium hydrosulfide, 9-14 parts of ammonium iron sulfate, 2-20 parts of abscisic acid, 4-5 parts of tryptophan, 4-5 parts of glutamine, 0.4-0.6 part of palladium nitrate, 0.1-0.3 part of magnesium hydrogen phosphate, 0.1-0.3 part of aluminum selenide, 0.04-0.2 part of phosphorus triselenide and the balance of water, and is obtained through the steps of weighing the components according to a compounding ratio and uniformly mixing the weighed components. When the nutrient solution prepared by the nutrient formula disclosed by the invention is adopted, during culture of seedlings, the osmotic force and the diffusibility of the nutrient solution are greatly improved, so that the time of emergence is greatly shortened, the rate of emergence and the quality of emergence are improved, and besides, the cost is reduced; in addition, the nutrient solution is more suitable for culture of seedlings at a high altitude and a low temperature.

Description

technical field [0001] The invention relates to a soilless cultivation nutritional formula, in particular to a soilless cultivation nutritional formula for roses. Background technique [0002] Roses like sunny, cold-resistant, drought-tolerant, well-drained, loose and fertile loam or light loam, poor growth and poor flowering in clay loam. It should be planted in a well-ventilated place far away from the wall to prevent sunlight reflection from burning the buds and affecting flowering. [0003] At present, the most reported is that flowers and tobacco adopt floating seedling raising technology. For floating seedlings, the most critical technologies include floating seedling substrates, soilless cultivation nutritional formula, etc. Among them, the soilless cultivation nutritional formula is particularly important for the improvement of seedling cultivation period, emergence rate and emergence quality, but the current soilless cultivation nutritional formula , Not suitable ...
