Nowadays, kiwi fruit gradually matures. Then, before and after harvesting, the fruit grower needs to pay attention to what, and Yang Ling Vocational Technology Professor Lei Zongzhong provides guidance for the majority of growers.
Protecting the leaves of fruit is about to mature, which is the best time for photosynthesis to accumulate nutrients. Care should be taken to protect the leaves. A fast-acting fertilizer can be topdressed for 15 days before harvest, and 0.3% to 0.5% Urea and 0.3% dihydrogen Phosphate can be sprayed on the leaves. Potassium and other 1 or 2 times, to ensure that the leaves are complete, thick and dark green.
Water Management Kiwifruit roots are fleshy roots with a shallow distribution and a small area; large leaves and large evaporation require timely hydration; Kiwi trees have a long stomatal opening time and increase evaporation, which determines that kiwifruit is an impatience. Drought fruit trees. The fleshy roots of kiwifruit are afraid of flooding. The demand for oxygen in the roots is relatively high. To build a garden in a low-lying land, you should plant trees along the trees to high ridges and prune the drains around the orchards. The drainage ditch is composed of a total drainage ditch, a dry ditch and a branch ditch, which facilitates the drainage of stagnant water in a rainy weather.
After the application of basal fertilizer, the basal fertilizer is applied in time and the tree body is supplemented with nutrients to lay a good foundation for the harvest of kiwifruit in the coming year.
Trim the fruit after light trimming. In combination with the application of harvested fruit fertilizer, a slight pruning is performed to remove dead branches, weak branches, diseased shoots, and the cut branches are burned in a concentrated manner to reduce the source of pest infestation. However, it should be noted that the fruit grower must Disinfect the trimming tool.
Post-harvest pests and diseases are one of the main causes of early deciduous defoliation of kiwifruit. It is imperative to do a good job of preventing and controlling pests in the orchard, ensure the integrity of the leaves, and postpone the deciduous time. With Bordeaux spray, lime sulfur or other bactericidal and insecticides can also be used.
