Embodiment 1
[0055] How to grow edible roses:
[0056](1) Pruning: On October 25, 2016, select 1-year-old healthy rose branches free from diseases and insect pests, cut them off from the lower end of the buds, with a length of 18-20cm, each with 4 buds, and put in a concentration of 0.1wt%. Take out after soaking in the potassium permanganate solution for 10 minutes to obtain 100 sterilized branches;
[0057] (2) cuttings: the sterilized branch is inserted in the culture medium, the depth of sterilized branch insertion is 50% of the total length of the sterilized branch, the row spacing is 5cm * 5cm, and the water content of the culture medium is replenished every day to make the water content of the culture medium between 58wt%. Indoor cultivation until March 20, 2017, the cultivation temperature is 25°C, the light intensity is 2000Lx, and the light time is 12 hours / day, and the rose seedlings are obtained;
[0058] The medium is fine sand containing ammonium sulfate with a coating layer...
Embodiment 2
[0073] The specific planting method and planting time are all the same as in Example 1, only the medium used in step 2 is different.
[0074] The culture medium used in this embodiment is fine sand containing ammonium phosphate with a coating layer, wherein the content of ammonium phosphate with a coating layer in the fine sand is 10 mg / kg;
[0075] The coating layer is nanometer zinc oxide;
[0076] The preparation method of the ammonium phosphate with a coating layer is as follows: use a coating machine to coat 9.8g / L nano-zinc oxide aqueous solution on the ammonium phosphate at a speed of 30rpm, and dry it with hot air at 60°C for 2 hours to obtain a coated layer. Ammonium Phosphate Coating.
Embodiment 3
[0078] The specific planting method and planting time are all the same as in Example 1, only the medium used in step 2 is different.
[0079] The culture medium used in the present embodiment is to contain the fine sandy soil that has coating layer ammonium molybdate, wherein has coating layer ammonium molybdate content in the fine sandy soil is 10mg / kg;
[0080] The coating layer is nanometer zinc oxide;
[0081] The preparation method of the described ammonium molybdate with a coating layer is: use a coating machine to coat 9.8g / L nanometer zinc oxide aqueous solution on ammonium molybdate at a speed of 30rpm, and dry it with hot air at 60°C for 2 hours to obtain It has a coating layer of ammonium molybdate.
