Water and fertilizer integrated fertilization method for kiwifruit

Abstract

The invention provides a water-fertilizer integrated fertilization method for a kiwi fruit. The method comprises the following steps of applying a pre-emergence fertilizer before sprouting in early spring; applying a fruit promoting fertilizer within 5-30 days after flowers fall; applying a fruit expanding fertilizer within 5-30 days after fruits come; and applying an overwintering fertilizer after the fruits are picked; and the method for applying the pre-emergence fertilizer, the fruit promoting fertilizer, the fruit expanding fertilizer or the overwintering fertilizer comprises the steps of dissolving various fertilizers into water and dripping fertilizer water into a root area of the kiwi fruit along with a drip irrigation facility. According to the method, the fertilizer is reasonable in proportion, an organic fertilizer is combined with an inorganic fertilizer and a bacterial manure, a macroelement and a medium trace element are fertilized at the ratio, so that the total amount, the ratio and the form conform to the absorption characteristic and law of the kiwi fruit. Fertilization and irrigation are reasonably carried out according to the growth period of the kiwi fruit, the requirements on nutrients and moisture at the nutritional requirement stage are met, the synergetic mutual promotion action among the nutrients is higher, the fertilizer utilization rate is improved, the labor intensity is reduced and the work efficiency is improved.

Description

technical field [0001] The invention relates to a kiwifruit water and fertilizer integrated fertilization method, which belongs to the technical field of kiwifruit planting. Background technique [0002] Actinidia is a perennial deciduous vine. Aerial part: The growth of branches is large and fast; the leaves are hypertrophic, the cuticle of the leaf surface is thin, and the stomata are open for a long time, so the evaporation of water in the aboveground part is large. Underground part: fleshy root system, shallow vertical distribution in the soil, wide horizontal distribution, no obvious backbone roots, but well-developed fibrous roots, with rooting peaks in May-July and September-November each year. Fruit part: high in vitamin content, rich in mineral nutrients, and more soluble solids than ordinary fruits, so it has the reputation of "king of fruits" and "crown of vitamins". The above characteristics determine that kiwifruit needs a stricter growth environment than othe...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the kiwifruit fertilization methods are partial application of chemical fertilizers, with a single nutrient ratio, and long-term use will cause soil acidification and compaction, which will weaken the kiwifruit tree and lower the quality of the fruit

Patent document CN103804047 A discloses a special fertilizer for Hongyang kiwi fruit and a fertilization method. The method combines organic fertilizers with inorganic fertilizers and adds active bacteria. It is a better fertilization scheme, but the application time of potassium sulfate in the formula is relatively long. After growing, soil acidification and compaction will occur, and the absorption and utilization of calcium by the root system of kiwifruit will be reduced; patent document CN104584756 A discloses a fertilization method for kiwifruit planting, which only contains bio-organic fertilizers and trace elements, and lacks large The addition of moderate elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc. is not conducive to the improvement of kiwifruit yield and quality, and this fertilization method is time-consuming and labor-intensive, and the labor cost is relatively large

[0005] In addition, the fertilization methods in the current patent literature on kiwifruit fertilization methods are digging trenches and fertilizing, which is time-consuming and laborious, with low work efficiency and huge labor costs, and this fertilization method cannot meet the water demand of kiwifruit during growth.

Through the search system of the Chinese patent database, no application or related literature has been found for the method of integrated fertilization of kiwifruit water and fertilizer.
