How to promote coloring in kiwifruit? Multiple measures help the fruit gain color
Spring management is an important stage in the growth-period management of a kiwifruit orchard, so doing a good job of spring management is especially important, and it should mainly start from the following aspects: 1. Supplementary pruning: due to the rain and snow last winter, some farmers pruned in a hurry, resulting in too many branches left and insufficiently thorough pruning of diseased and pest-infested branches...
Balanced fertilization The growth of kiwifruit is divided into three stages. In the early stage (March to May), vegetative growth dominates, and fertilization should emphasize nitrogen; in the middle stage (June to August), reproductive growth is dominant, and fertilization should focus on phosphorus and potassium, combined with foliar fertilizer spraying, and reduce the amount of nitrogen fertilizer; the late stage (September and October) is the period when vegetative growth and reproductive growth advance together, so organic fertilizer, chemical fertilizer, mineral fertilizer and microbial bacterial fertilizer should all be applied together to improve the soil environment and promote the accumulation of nutrients in the tree.Control of moisture in kiwifruit During the fruit expansion period, watering should be timely and appropriate to keep the soil from drying out, so as to increase fruit size and raise yield. Controlling water in the later stage can promote sugar accumulation and coloring of kiwifruit. In the later stage of orchard management, water less or not at all depending on the situation, open up the light path, and help the fruit color.
Laying reflective film In the later stage of kiwifruit growth, where conditions permit, it is advocated to lay reflective film under the tree canopy to promote fruit coloring.
Timely harvesting Late-maturing varieties have a long growth period, and the harvest period should be in mid-October. Medium-maturing varieties have a slightly shorter growth period, and the harvest period should be in early to mid-September. Harvesting too early will affect fruit coloring.
