He saw that he was spraying a milky white liquid on the orange trees. "Master He, are you spraying the Guanggan Tree? Steaming, smelling there is a fragrance," the author asked. "It's not milk, it's a starch solution. Spray it on the orange tree to protect the leaves safely for the winter." He Yuren rushed around and answered. The orange tree he had sprayed starch liquid on, viewed from afar, the leaves were covered with a thin film. He said that don't underestimate this layer of "film", the winter citrus tree has it, it can inhibit the transpiration of the leaves, there is a certain degree of insulation effect. “From 2007 onwards, every year after the winter solstice, I sprayed the orange trees with starch. After several years of operation, all the trees that sprayed with starch liquid had green leaves, fewer leaves, and less freezing injury. The fruit setting rate was significantly higher than that of non-spraying. "The tree." "Imagine that this milk-like starch solution has such a magical effect. Is there any mysterious recipe?" I asked. "Actually, it's very simple." He Yu-won replied that he used the common sweet potato flour and Pueraria powder to make starch, and then used cold water to transfer 1 kg of starch into a thin paste and pour it into a pan with 5 pounds of water. Bring to boil, pound paste and then add 100 pounds of water, Serve 1% starch solution. In addition to drinking "milk" from the orange trees, He Yurui also reminded that if the orange trees are safe for winter, they must pay attention to fertilizer management. “General Shengshushu Shi applied 50 jins of livestock manure, 10 jins of vegetable glutinous rice cake, and 10 pounds of superphosphate, and the initial fruit tree was applied in an amount of 2/3.†He said that the specific method is to open two lines under the canopy dripping line. The deep symmetry groove or ring groove is applied, and the water is covered to cover the fine soil. He also suggested that after winter, all orange trees were sprayed with Baume 3 degree lime sulfur for 1 to 2 times to kill rust wall ticks, red spiders, yellow spiders, and scale insects to reduce the wintering base of the pests.
