Planting techniques of long Fruit Mulberry in Taiwan

Soil: Taiwan long fruit mulberry can be planted in areas with fertile soil and deep soil layer. Reasonable planting: ditching, applying sufficient base fertilizer, and reasonable close planting according to a certain spacing between plants and rows. Branch cutting: the seedlings can be cut short and dry at 30cm from the ground. Rational fertilization: adequate basal fertilizer, foliar spraying with potassium diammonium phosphate from flowering to young fruit stage. Heart-picking: heart-picking is carried out around May, at the end of June and at the end of July, and it is necessary to apply fertilizer and water in time after heart-picking.

1. Growing soil

Long-fruit mulberry does not have high requirements for growing soil, and most of the soil can be planted. If you want to have high yield, you should choose to plant in areas with fertile soil and deep soil layer.

II. Rational planting

The main results are as follows: 1. Before planting, the ditch should be about 60cm wide and 50cm deep, then spread a layer of crop stalks with a thickness of 20-30cm at the bottom of the ditch, then cover the soil with about 10cm, and apply farm manure to the topsoil. finally, about 50 kg compound fertilizer can be applied per mu to backfill all the topsoil.

2. When planting, plant spacing is about 2-3m, row spacing is about 3-3.5m, planting is about 63-110 plants per mu, plant spacing on hillside and meager land is about 1m, row spacing is about 2m, and about 333 plants can be planted per mu. Compaction after planting, sufficient root water can be poured, such as serious drought areas need to increase watering times, so as to ensure plant survival rate.

Third, branch cutting

The main results are as follows: 1. After planting, the seedlings can be cut short and dry from the ground 30cm, and the top center can be removed when the new shoots grow to 20cm, which is beneficial to promote branching.

2. The main purpose of planting is to raise trees in that year, but the requirement for fruit rate is not high. In the second year, the mother branch can be cut short, leaving only 2-3 sprouts, and urea and quick-acting fertilizer are applied at the same time, which is beneficial to promote its growth and lay the foundation for high yield in the coming year.

IV. Rational fertilization

1. After the harvest is completed every autumn, sufficient base fertilizer should be applied in the middle of the planting line, mainly farm organic fertilizer and human and animal manure, with 50 kg compound fertilizer per mu, which is beneficial to promote flower bud differentiation and create conditions for high yield in the coming year.

2. From flowering stage to young fruit stage, potassium diammonium phosphate can be used for foliar spraying, which is beneficial to improve yield and quality.

Fifth, pick the heart

The main results are as follows: 1. In order to increase the yield, the coring of the plant can be carried out at the right time, usually from April 20 to May 10, June 20 to 30 and July 20 to 30.

2. After three times of coring, the general plant will grow about 15-18 fruiting mother branches, up to a maximum of about 20. Note that after each coring, fertilizer can be applied reasonably according to the growth of the plant, and 5-10 kg of urea can be applied per mu. The effect is good after rainfall. If there is no rain, it can be watered after fertilization.

VI. Prevention and control of diseases and insect pests

Long fruit mulberry is a hybrid variety with good disease resistance. the main diseases are powdery mildew and high resistance to Sclerotinia sclerotiorum.
