A number of measures to promote kiwifruit coloring

The growth of kiwifruit can be divided into three stages by balanced fertilization. the vegetative growth is dominant in the early stage (March to May), and nitrogen should be emphasized in fertilization; in the middle stage (June to August), reproductive growth is dominant, fertilization should be dominated by phosphorus and potassium, combined with foliar fertilizer spraying. reduce the amount of nitrogen fertilizer In the later stage (September and October), vegetative growth and reproductive growth are in progress, and organic fertilizer, chemical fertilizer, mineral fertilizer and microbial fertilizer should be applied together to improve the soil environment and promote the accumulation of tree nutrition. In order to control the fruit expansion period, kiwifruit should be watered timely and appropriately to keep the soil from water cut off so as to increase the fruit number and increase the yield. Water control in the later stage can promote the sugar increase and coloring of kiwifruit. In the late stage of orchard management, it depends on whether the orchard is watered less or not, open the light path and help the fruit coloring. Laying reflective film in the later stage of kiwifruit growth, it is recommended to lay reflective film under the tree plate to promote fruit coloring. The growth time of late-maturing varieties of timely fruit picking is long, and the fruit harvest period should be in the middle of October. The growing period of mid-ripe varieties is slightly shorter, and the fruit harvest period should be in mid-early September. Picking fruit early will affect the coloring of the fruit.
