Cultivating method for winter jujube tree

Abstract

The invention discloses a cultivating method for a winter jujube tree and relates to the technical field of fruit tree cultivation. The cultivating method comprises the following steps: 1) furrow application for wet chicken manure: performing furrow application for wet chicken manure during the dormancy stage of the winter jujube tree; 2) watering: watering for one time in the last ten days of the dormancy stage of the winter jujube tree; 3) watering: watering after the winter jujube tree enters flowering phase and watering for one time in the early flowering phase; 4) spraying pesticides: spraying pesticides after the winter jujube tree enters later flowering phase; 5) watering: watering for one time after the winter jujube tree enters young fruit period; and 6) watering: after the percentage of fertile fruit of the winter jujube tree is above 90%, watering one time per day, and stopping watering at the moment of frost descent. The cultivating method has the advantages that: the annular furrow application for wet chicken manure is adopted; after watering is performed, the absorbable nutrition of the wet chicken manure is directly absorbed by the root system of the winter jujube tree; according to the annular furrow application method, the absorbing area of the root system is increased; the nutrient is more sufficient; the yield of single plant is efficiently increased; 10-15kg of dry winter jujubes are generated by a ten-year tree; the sugar content is about 40%; and the dry winter jujubes are directly obtained by airing.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation. Background technique [0002] Winter jujube is fresh and delicious, with crispy skin and excellent meat quality. It is currently a high-grade fresh food variety among deciduous fruit trees in northern China; it can crack when it falls on the ground when it matures; it is juicy and slag-free, sweet and fragrant; 35-38% soluble solids, The meat is thick and the nucleus is small, and the edible rate reaches 96.1%. [0003] Winter jujube is extremely nutritious. Contains 19 essential amino acids such as aspartic acid, threonine, and serine, with a total content of 0.985mg / 100g; protein 1.65%; dietary fiber 2.3%, total 17.%; total flavonoids 0.26%; niacin 0.87mg / 100g; carotene 1.1mg / kg; vitamin B1 0.1mg / kg; vitamin B2 2.2mg / kg; the content of vitamin C is especially rich, reaching 352mg / 100g; times, 20 times that of Jinsixiaozao, and has the reputation of "live vitamin pills".

Problems solved by technology

However, due to the backward cultivation methods of winter jujube trees at present, if perennial winter jujube trees have entered the normal flowering and fruiting stages, topdressing should be carried out 3 times throughout the year, respectively in the germination stage, fruiting stage, and fruit expansion stage. Nitrogen and phosphorus are mainly used in the fruit expansion period, and the combination of nitrogen, phosphorus and potassium is required in the fruit expansion period. Watering is mainly carried out three times, watering once before the germination period, before the flowering period and the young fruit period, and watering all three times. With the current method of cultivating winter jujube trees, the output of a single winter jujube tree can only reach 10 kg of fresh winter jujube, and the current winter jujube can only be sold as fresh fruit, it is difficult to obtain dry winter jujube through natural methods. In addition, due to unreasonable watering, the fruit Not full enough, the sugar content can only reach about 20%
