The latest course of planting techniques and methods of indigo fruit

Blue indigo fruit, also known as goat milk, black blind fruit, etc., it is a rare, pure natural edible berry, sour and sweet taste, rich, can be eaten raw, but also can provide pigment, can also make wine, drinks and jams, high edible value. In addition, it has extremely high nutritional value, can not have the effect of heat-clearing and detoxification, but also can reduce blood pressure, improve the blood cell tree, and treat infantile anorexia. So how should it be planted? Let's get to know it.

1. Land selection and preparation

Choose sufficient light, convenient irrigation, flat or gentle slope land can be planted, it is appropriate to choose loose and fertile sandy loam or sandy soil with good drainage, the best pH value is between 4.5 and 7.5. In order to facilitate management, picking and sales during cultivation, it is best to plant in areas with convenient transportation. Before planting, the soil was deeply ripe, weeds and residual plants were removed, and rotten organic fertilizer was applied during ploughing to improve soil properties, increase soil nutrients, and make plants have sufficient nutrients for growth and development.

2. Reproduction

The propagation methods of indigo include sowing, cutting, ramet and other propagation methods. When sowing, the ripe fruit is picked and the seeds are taken out and stored in wet sand. After next year, choose the zone where the soil is fertile and loose and well drained to sow seeds, which can be planted after two years of cultivation. The cuttage generally begins when the temperature rises above 15 degrees in spring, select the branches of the mother plant in the same year as cuttings, smear rooting powder at the base, then cut them in fertile land, and cultivate them for 2-3 years. The sprouting ability of indigo is very strong, so ramet propagation is that after selecting the root strip, it can be planted on fertile soil, and the survival rate is as high as 95%.

3. Colonization

The strong seedlings cultivated by improved varieties should be selected during planting, which requires strong seedling growth, developed root system and full bud eyes. the seedlings with seedling height above 25cm and main root length above 25cm are preferred. Generally, the blue indigo fruit cluster of the forest can be as high as 1.5-2 meters, and the crown width can reach 2-2.5 meters, so when planting, in order to maintain the ventilation and light transmittance between the plants, it is generally necessary to control the row spacing at 4 × 4 meters. Generally, there are more than 600 planting holes per hectare, and the plant is suitable for each hole, and the row distance between the control plant and the plant is 20 × 20 cm. When planting, straighten the seedlings, step on the soil, and pour water once after planting, so that exuberant plants can be formed as soon as possible.

4. Inter-park management

After the planting survived, water should be watered frequently to keep the soil water content above 40% to meet the water demand of the plant. At the same time, if the soil stagnant water should be drained in time. Blue indigo likes fertilizer, but is more sensitive to chemical fertilizer, so fertilizing as far as possible to apply farm fertilizer, avoid using chemical fertilizer, in order to maintain the purity of green food. After planting, weeding should be done 2-3 times a year according to the soil and weeds in the field to promote the growth of plant roots. The blue indigo fruit has strong germinating ability. in order to add new branches to the plant cluster, it is necessary to cut it with flat stubble to promote its germination of new branches.
