High-yield measures for planting Zizyphus jujuba

We ate a lot of jujube when we were young. Its fruit tastes sweet and colored, and it can also be used to make soup. It tastes better. In the past, it was mostly wild, but now it can no longer be seen. Now there are artificial cultivation in many areas. But the yield of many people is not high, let's take a look at the high-yield measures of jujube planting with the editor below.

1. Sowing and sprouting and plastic film mulching at seedling stage

Zizyphus jujuba is generally sown from February to April in spring, when the temperature is slow and the seed stem germinates slowly, so the seed stem should be treated with accelerating germination before sowing. Use a hotbed for sprouting indoors, keep the temperature at 20 degrees, you can sprout in half a month, or you can set up a grid outside, keep the temperature between 20 and 25, treat it continuously for 15 days, and wait for the seed coleoptile to turn white. Cover with plastic film after sowing, as long as the plastic film covers the rows with seed stems, wait for the seedlings to be removed, so as not to affect the normal emergence of seedlings.

2. Timely irrigation and drainage and topdressing on time

Jujube likes a humid environment, is resistant to fertilizer, and is afraid of stagnant water. before planting, it is necessary to water the planting land once to facilitate the emergence of seedlings, keep the soil moist during the seedling growth period, water in time in case of drought, and drain in time in the rainy season to avoid stagnant water in the field and die the seedlings. The fertilizer is mainly farm manure. In addition to applying sufficient base fertilizer, topdressing should be applied twice during the growing period. The first topdressing is from May to June. When buds grow in the lower part of the petiole, 2000 kg of mature farm manure and 25 kg of cake fertilizer are applied per mu. For the second time, 20 kg of rotten cake fertilizer, 15 kg of calcium superphosphate and 10 kg of urea were applied per mu when new buds and roots appeared in August.

3. Intercropping of high-stem crops

Zizyphus jujuba is a shade-tolerant crop, which grows well in a hidden environment and has a high yield, so planting a box of half-shaded and half-sunny gentle sloping land can be interplanted with young fruit trees, corn, wheat and other crops to provide shade and create a suitable growth environment.

4. Picking buds and delaying seedling falling

After sowing for two months, the planting will bolt and blossom one after another, and it is very easy to consume nutrients, so in addition to leaving seeds, it is necessary to remove flower buds in batches in time, so that nutrients are concentrated in underground tubers, accelerate tuber growth and increase yield obviously. High temperature and strong light will appear the phenomenon of natural lodging and stop growing, so delaying seedling falling is an important measure for high yield of Zizyphus jujuba. In cultivation, appropriate shading and sprinkler irrigation measures to reduce light intensity, air temperature, or spraying sodium sulfite solution can inhibit plant respiration, thus shorten seedling stage and reduce seedling times, and achieve high yield.

The above is the introduction of high-yield measures for jujube planting. I hope it can help you. If you want to know more about it, please follow us.
