Planting techniques of Auricularia auricula in summer and autumn

Muercai is also called Basella, rattan vegetables, tender stems and leaves for food, high nutritional value. Because of its heat resistance and rapid growth, it is suitable for rapid cultivation in summer and autumn. The cultivation techniques of Moschus auriculatus are introduced as follows:

1. Cultivation methods

Summer and autumn cultivation, do not have to germinate. The seeding amount per mu is 6-8 kg, and the effective number of seedlings is 30,000 plants per mu.

II. Selection of varieties

It is advisable to select high-quality, high-yield and disease-resistant varieties of red stem and green stem Muer.

III. Field management

management methods

To feed on tender shoots mainly, in the seedling height of about 30 cm when leaving 3~4 leaves at the base, harvesting tender head shoots, leaving two robust lateral buds into shoots. When harvesting the second shoot, leave 2~4 lateral buds to form shoots. In the vigorous growth period, each plant has 6~8 robust lateral buds to form shoots. In the middle and late stages, the young buds of flower stems should be wiped off in time. In the later stage, the growth is weak, leaving 1~2 robust lateral shoots to facilitate the hypertrophy of leaves.

For the purpose of feeding leaves, it is necessary to erect a frame for cultivation. When the seedling height is about 30 cm, a herringbone frame is erected to lead the vines to the upper frame. In addition to keeping the main vines, two strong lateral vines are left at the base to form the backbone vines. When the backbone vines grow to the top of the frame, they are picked. After picking, a strong lateral bud is left from each backbone vine. The stem vine is cut off after the leaves are picked. Soil should be cultivated before putting on shelves and after each harvest, or young shoots can be harvested without pruning.

2. Intertillage and weeding

After direct seeding, during the growth period, intertill and weed in time to prevent weeds from competing for nutrients.

3. Fertilization and watering

Base manure to farm compost, livestock manure is good. Topdressing is applied with decomposed human and livestock manure or urea dissolved water. After emergence, keep the soil moist and water it timely. After each harvest, urea 10 kg should be applied in time, and drainage should be carried out in time to prevent waterlogging in rainy season.

4. Prevention and control of diseases and pests

The common disease of Schima auriculata is brown spot disease, which can be sprayed with 500~600 times solution of 72% Kelu WP at the initial stage of occurrence.

If Spodoptera litura occurs, more young leaf tips are found to have small eyes, and pyrethroids can be sprayed once at the 1~2 instars.

Root-knot nematode disease may also occur in continuous cropping of M. arborescens, and crop rotation can reduce or avoid the occurrence of this disease.

IV. Scientific harvesting

To pick tender shoots mainly, when the seedling height of about 30 cm when the base of 2 true leaves with scissors cut, germination of lateral branches have 5~6 true leaves and then according to the above method of harvest. Young leaves are mainly harvested once every 15~20 days in the early stage, 10~15 days in the middle stage and once every 7~10 days in the late stage. The harvested leaves should be fully unfolded without aging and thick. Generally, the yield of tender shoots per mu is 2000~4000 kg. Cai Shuangwen
