Cultivation techniques of Lingwu jujube: where can the saplings be sold, and the shelf life of Lingwu jujube can be increased by 10 times?

   reporter learned from the Science and Technology Department of the Autonomous region yesterday that the Science and Technology Department and the Forestry Department organized experts from forestry, fruits and vegetables, and food to carry out on-site acceptance of the room temperature fresh-keeping research part of the first nationwide bidding project of "key Technology Development and Research of Lingwu long Jujube Storage and Transportation Insurance". The results showed that the shelf life of Lingwu long jujube was 10 times longer than before, and it was stored at room temperature for 30 days.

   reported that Lingwu Changzao jujube has already entered the southeast coast and Hong Kong and other high-end markets, but because Lingwu Changzao jujube is easy to lose water, alcohol, wrinkle, flesh soften, browning, rot, the shelf life of Lingwu Changzao jujube is only 3 to 5 days at room temperature, which greatly hinders the shelf life of Lingwu Changzao jujube. Last year, the fresh-keeping technology of Lingwu jujube was listed as a major scientific and technological project in the autonomous region and was invited for public bidding throughout the country. The successful bid-winning School of Food Engineering of Tianjin University of Science and Technology, the Institute of Resources and varieties of the Chinese Academy of Forestry Sciences and the Institute of Storage and processing of Agricultural and sideline products of Gansu Academy of Agricultural Sciences were organized. technical research was carried out from three aspects: disinfection and sterilization, application of special fresh-keeping film, fresh-keeping coating agent and film.

   after nearly two years of research, three sets of room temperature fresh-keeping technology came out. Lingwu Changzao jujube was stored at room temperature for 30 days, with a good fruit rate of 91.8%, in line with commodity standards. The Department of Science and Technology will organize domestic authoritative experts next year to systematically evaluate three kinds of fresh-keeping technology and determine the industry-oriented fresh-keeping technology and supporting technology.

(2) cultivation and management

1. Raising seedlings: the nursery should choose the land with flat terrain and smooth drainage and irrigation, and it is suitable to use sandy loam and light loam. The seed of rootstock is wild jujube seed or wild jujube seed. The one-year-old jujube head branches of mature fruit trees with pure varieties, strong growth, high yield, high quality and no diseases and insect pests were selected as scions for grafting and propagation.

2. Build the garden: choose the land with deep soil, fertile soil, convenient drainage and irrigation, and convenient transportation. Sandy loam or light loam with a groundwater level below 1.5 meters, a mature soil layer of more than 30 cm, a pH value of 7.5 to 8.5, and a high content of organic matter.

3. Shaping and pruning: spindle shape, small crown shape and happy tree shape are adopted. Winter shears are mainly thinning, and jujube heads are cut short to cultivate backbone branches. Summer shears mainly include sprouting, heart-picking, branch pulling and branch thinning measures. The planting density does not exceed 110 plants per mu.

4. Fertilizer and water management: balanced fertilization, promoting and controlling before and after. Mainly organic fertilizer, according to the proportion of timely topdressing. Pay attention to drought prevention in the early stage, timely irrigation, and control irrigation after the middle of August.

5. Flower and fruit management: measures such as coring, foliar fertilizer spraying at flowering stage, opening armour (ring cutting) for growing trees in fruiting stage, and releasing bees at flowering stage to improve fruit setting rate. Adjust the tree potential, reasonable load, improve fruit quality.

Where the saplings are sold, they are usually bought in the sapling store. Otherwise, you can also buy it online.
