How to grow Japanese raisin tree for high yield? The latest measures explained in one article

Many of us ate Japanese raisin tree fruit as children. Its fruit tastes sweet with a hint of astringency, and it can also be used in soup, with a fairly good flavor. Most were wild in the past, but now they are basically nowhere to be seen, and today many areas grow them by cultivation. However, many people do not get high yields. Below, let us take a look at the high-yield measures for growing Japanese raisin tree.

1. Sowing and sprouting, mulching at the seedling stage

Japanese raisin tree is generally sown in spring from February to April. Because the temperature is slower at this time and the seed stems sprout slowly, the seed stems should be sprouted before sowing. Sprout them indoors in a hotbed, keeping the temperature at 20 degrees, and they will sprout in half a month. They can also be sprouted outdoors in a frame, keeping the temperature between 20-25, treating them continuously for 15 days, until the seed coleoptile turns white. After sowing, cover with plastic film. The film only needs to cover the rows where the seed stems are planted, and it should be removed after the seedlings emerge evenly, so as not to affect normal emergence.

2.   Timely drainage and irrigation, topdressing on schedule

Japanese raisin tree likes a humid environment, tolerates fertilizer, and fears waterlogging. Before planting, water the planting site thoroughly once to help emergence. During the seedling growth period, keep the soil moist, water promptly during drought, and drain promptly during the rainy season to avoid waterlogging in the field causing seedling death. Fertilizer should be mainly farmyard manure. In addition to applying sufficient base fertilizer, topdress 2 times during the growth period. The first topdressing is in May-June, when bulbils grow on the inner side of the lower part of the leaf stalk, applying 2000 kg of decomposed farmyard manure and 25 kg of cake fertilizer per mu. The second is in August, when new buds appear and new roots grow, applying 20 kg of decomposed cake fertilizer, 15 kg of superphosphate, and 10 kg of urea per mu.

3. Intercropping with tall crops

Japanese raisin tree is a shade-tolerant crop and grows well in shaded environments with higher yields, so plant it on a gently sloping field with half shade and half sun. If planting on flat land, it can be intercropped with young fruit trees, corn, wheat, and other crops to provide shade and create a suitable growing environment.

4. Removing buds and delaying dieback

Two months after sowing, the plants will successively bolt and bloom, which easily consumes nutrients, so aside from those kept for seed, the flower buds should be removed in batches in time so that nutrients concentrate in the underground tubers, speeding up tuber growth and clearly increasing yield. Japanese raisin tree will naturally lodge under high temperature and strong light and stop growing, so delaying dieback is an important measure for high yield. In cultivation, taking appropriate shading and sprinkler irrigation measures to reduce light intensity and air temperature, or spraying sodium sulfite solution, can inhibit plant respiration, thereby shortening the dieback period and reducing the number of diebacks to achieve high yield.
