Taiwanese jujube, also known as Taiwan sweet jujube, is an excellent fruit variety selected and bred by the Indian hairy leaf jujube through many generations of improvement. Its fruit is large, fine, crisp and sweet, high nutritional value, deeply loved by consumers, and has the characteristics of early fruiting and strong adaptability, and good planting benefits. The following small editor sent to introduce the efficient planting technology and management points of Taiwanese jujube, let's take a look.
1. Garden selection
Taiwan jujube is suitable for planting in places with high temperature, short frost period, sufficient sunshine, fertile soil, convenient drainage and irrigation, and leeward wind.
For large-scale orchards, simple planning should be done in advance. For example, workers' housing and warehouses should be built in places with high terrain, convenient transportation, open field of view, easy to observe, manage, and guard; Generally, a channel should be built at a distance of about 200m in order to transport fertilizer, medicine, fruit, etc.; There should be a cistern or septic tank every 200m distance; The construction of the water supply system should be economical, labor-saving and convenient; The construction of drainage channels should be both simple and effective. However, different terrains have different requirements, and the planning of the park should be determined according to the actual situation.
2. Planting specifications
The planting specifications are suitable for planting 20 to 30 plants per 667 square meters, and the plant row spacing can be 6m×6m, or 5m×5m or 4m×5m. Flat and fertile areas can be appropriately sparse, and the slopes can be properly dense.
3. Planting requirements
The planting requirements of jujube in Taiwan are generally planted by digging holes, and the hole specifications are 1m×1m×1m. Dig the hole and then return to the soil. Before returning to the soil, apply 0.5kg of quicklime powder to each hole, then fill in weeds, green manure 5 to 10 cm thick, then fill the soil with 10 to 15 cm, and then sprinkle quicklime on it, and then apply 20 to 30 kg of decomposing manure, 2 to 3 kg of cake fertilizer, and 1 to 2 kg of phosphate fertilizer. The decomposed manure, phosphate fertilizer and cake fertilizer applied must be mixed with the excavated topsoil before being backfilled, so as not to cause the seedlings to burn roots; Finally, the excavated topsoil is filled in, and the backfilled soil must be 20 to 30 cm higher than the original ground. Where the terrain is low, it is best to pile up a small mound and then plant it, so as not to accumulate water and make the seedlings rot roots.
4. Timely planting
The best time to grow dates in Taiwan is from January to April. The earlier it is planted, the longer it grows, and the higher the yield of the year; At other times, although the fruit is still bearable in the same year, the yield is very low, and the survival rate of the seedlings planted is very low. Before loading and transporting seedlings, the young parts of the seedlings should be cut off; The planting time is best selected on a cloudy or sunny evening, with bagged seedlings or mud seedlings.
Planting should not be too deep, the soil as long as the root cover 2 to 3cm can be, planting too deep, easy to accumulate water, poor root permeability, plant growth slowly, and even rotten roots die. However, if it is planted on a hillside or in an arid garden, it can be planted deeper appropriately. After the seedlings are planted, gently step on the soil with their feet, pour enough root water, and cover the planting hole with 3 cm of straw to prevent the evaporation too quickly. If it does not rain after planting, water once a day, water continuously for 3 to 5 days, if planting, in hot weather, it is best to use bamboo poles, branches, straw or shade nets to build a low shed to shade the seedlings, in order to prevent direct sunlight, causing leaf moisture to evaporate quickly, affecting the survival rate, after a week can be bamboo poles, branches and other shade materials can be uncovered. About 20 days after planting, the graft film can be gently cut off with a sharp knife so as not to affect the growth of seedlings.
The above is the efficient planting technology and management points of Taiwan jujube, Taiwan jujube fruit is oblong-oval after ripening, the core fruit is large, the skin is bright green, the flesh is white, and the nutrition is rich. Farmers who want to grow Taiwanese jujube can master the above planting techniques and management points to obtain the purpose of high yield.
