1. Control the humidity and temperature: Nectarine enters the coloring phase and requires daytime temperature 25-28 degrees, no more than 30 degrees, night temperature 15 degrees, can not be lower than 12 degrees, and air humidity should be controlled below 60% to facilitate coloring .
2, increase potassium fertilizer: nectarine fruit into the coloring period, the demand for potassium is higher, timely application of potash fertilizer, can significantly increase yield and increase fruit sweetness. In addition to spraying 0.5% potassium dihydrogen phosphate solution on the leaves, potassium sulfate or potassium-containing compound fertilizers and plant ash may be used. Generally, 0.25 kg of potassium sulfate is applied per plant, or 0.5 kg of compound fertilizer is applied, or 2-4 kg of plant ash are applied, and appropriate amount of water is applied after fertilization.
3, increase the light: In order to achieve the purpose of coloring the greenhouse nectar, we must take measures to increase light, so that the intensity of light in the greenhouse increase, improve the light conditions of the tree. Generally, it is possible to use a reflective curtain on the wall, a reflective film under the tree, and a method of cleaning the facade. In the premise that the indoor temperature is not lower than the required temperature of the peach tree, as soon as possible to demolition of the curtain, cover the curtain in the evening, in order to promote fruit surface color.
