How should kiwifruit be fertilized? We also ask netizens with kiwifruit growing experience to help provide a detailed introductionKiwifruit is fresh and tender in quality, rich in nutrition, and delicious in flavor. It is a fruit that people love to eat, has a beauty and skin-nourishing effect, and helps delay skin aging. It is deeply loved by people of all ages, so the demand for kiwifruit is also increasing day by day. Zhongdi Network has compiled the fertilization methods for kiwifruit at each stage, listed in detail below for netizens' reference.
1. Topdressing with bud-promoting fertilizer in early spring:
After the soil thaws in spring and the sap flows, the tree body begins activity. Fertilization at this stage is beneficial for budding and flowering and promotes new shoot growth. The bud-promoting fertilizer should be applied before kiwifruit sprouts, mainly with quick-acting nitrogen fertilizer (nitrogen fertilizer accounting for 1/2-2/3 of the annual nitrogen fertilizer amount) combined with a small amount of phosphorus and potassium fertilizer. For a 4-year-old tree, generally apply 8-10 kg of pure nitrogen, 4 kg of pure phosphorus, and 4 kg of pure potassium per mu. Broadcast over the whole orchard or apply per plant, then irrigate with spring water 1-2 times.
2. Topdressing with fruit-promoting fertilizer after flowering:
The 30-40 days after kiwifruit flowers fall is the period when kiwifruit fruit rapidly expands. At this stage, the fruit grows quickly and its volume increases rapidly. Lack of fertilizer will hinder kiwifruit expansion. The fruit-promoting fertilizer should be applied 20-30 days after kiwifruit flowers fall, mainly with quick-acting compound fertilizer. For a 4-year-old kiwifruit tree, 0.25-0.3 kg of monopotassium phosphate can be applied per plant. After application, irrigate the whole orchard once.
3. Topdressing with fruit-strengthening fertilizer in midsummer:
To make kiwifruit fruit more substantial internally, increase single fruit weight, and improve quality, apply phosphorus and potassium fertilizer once in June-July. To make up for the insufficient nutrition during later shoot growth, quick-acting nitrogen fertilizer can also be sprayed on the leaves 1-2 times. Spraying calcium fertilizer on the leaves at this stage can also enhance the storage tolerance of the fruit. This fertilization should mainly be foliar spraying, and 0.5% monopotassium phosphate, 0.3-0.5% urea solution, and 0.5% calcium nitrate can be selected.
4. Basal application of overwintering fertilizer after fruit harvest:
After kiwifruit harvest, the leaves lose a large amount of nutrients, so supplementing the tree body with nutrients at this time is especially important. Before leaf fall, spray 0.5% urea solution once on the leaves to increase leaf photosynthesis, promote the return of nutrients to the roots and stems, and increase nutrient reserves. In autumn, basal fertilizer should be applied early, mainly with organic fertilizers such as pen manure, composted fertilizer, compost, barnyard manure, and cake fertilizer, and mixed with some quick-acting fertilizers such as superphosphate and ammonium nitrate. Generally, for a 4-year-old tree, apply 20-30 kg of organic fertilizer per plant, plus 0.25 kg of superphosphate and ammonium nitrate. Broadcast over the whole orchard or apply in strip trenches. Irrigate once promptly after application.
