Matters needing attention in planting winter jujube

Winter jujube, also known as apple jujube and wild goose jujube, is a kind of jujube which matures from October to November. It has crisp taste and high nutritional value. Many people like to eat it, and it is planted widely in our country. However, there are many misunderstandings in planting, which affect the yield and quality of winter jujube. Let's take a look at the planting points for attention with the editor.

1. Selection of species and sites

Seed selection is a crucial step to grow winter jujube with good yield and quality. nowadays, the planting technology is more perfect, but there are many varieties of winter jujube, and each variety has its own characteristics, advantages and disadvantages, and its adaptability to the environment is also different. Therefore, there are corresponding varieties in different regions, and the excellent varieties suitable for planting should be selected according to the local climate, soil and other factors. The planting land should be planted in areas with flat, sunny, loose and fertile soil and close to water sources.

2. Reasonable close planting

Under the condition of sufficient nutrients, the branches and leaves of winter jujube grow very fast, so the planting density should be done first, and the planting density should be determined according to the growth habits and soil fertility of winter jujube. The general planting density is 3 meters between rows, and the plant spacing is about 2 meters. According to this density, 50-100 winter jujube trees can be planted per mu, and the planting density can also be increased or decreased according to the actual situation.

3. Rational fertilization

In order to save time and effort, many farmers use the method of applying sufficient base fertilizer at once and not applying nitrogen fertilizer in the later stage, or applying nitrogen fertilizer in the fruit stage without base fertilizer, and topdressing by stages, but these fertilizers are too single. Fertilization methods are wrong. When fertilizing winter jujube, nitrogen, phosphorus and potassium should be reasonably matched and indispensable. Partial application of nitrogen fertilizer will easily lead to overgrowth of plants and delay of flowering and fruiting; partial application of phosphate fertilizer will lead to thick leaves and Milan, and branches are easy to age; partial application of potassium fertilizer will lead to narrow, black and thick leaves, which is not easy to draw new branches, which is disadvantageous to crown regeneration. Therefore, in fertilization, we should give priority to fertilization and topdressing fertilizer as a supplementary principle, reasonable topdressing of nitrogen, phosphorus and potassium fertilizer in the growing period, nitrogen fertilizer in the early stage, phosphorus and potassium fertilizer as a supplement, phosphorus and potassium fertilizer in the middle and later stage to reduce the amount of nitrogen fertilizer application.

4. Florescence management

The florescence management of winter jujube is very important, which is related to fruit setting rate and fruit setting rate. Winter jujube is a multi-flowering, light-loving and drought-tolerant tree species, which requires higher temperature and humidity at flowering stage. If the flowering period is long-term drought, the temperature is higher than 25 degrees and the humidity is less than 25%, the pollen will not germinate and the pollination effect is poor, so it is necessary to water several times during the flowering period to maintain the soil moisture and control the humidity. Flowering is also a period of high incidence of insect pests, when jujube gall midges, green bug bugs, bug bugs, beetles, heart-eating insects and so on will harm planting, harmful flowers and fruits, so timely medication to control insect pests.

The above are the matters needing attention in the planting of winter jujube. I hope I can help you. If you want to know more about it, please follow us.
