Cultivation techniques of Auricularia auricula in Summer and Autumn

Auricularia auricula vegetables, also known as sunflower, rattan vegetables, with tender stems and leaves for consumption, high nutritional value. Because of its heat resistance and rapid growth, it is suitable for rapid cultivation in summer and autumn. Commonly used varieties are: red sunflower, green stem sunflower, broad-leaf sunflower, white sunflower and so on. According to the different feeding parts of Auricularia auricula, it can be divided into non-framing cultivation (feeding tender shoots) and framing cultivation (feeding tender leaves).

Auricularia auricula

Before sowing, 2500kg mature organic fertilizer and 450kg superphosphate were applied per mu, deep ploughing, raking and spraying 200g no-deep tillage soil conditioner per mu to promote the looseness and permeability of the deep soil. Make a flat bed. Soak the seeds in warm water of 35 ℃ for 2 days before sowing and cultivate them in summer and autumn without sprouting. With the seed amount of 8 kg per mu, the effective seedling protection number of Auricularia auricula is 30,000 plants per mu.

After emergence, the seedlings are interspersed and fixed. The row spacing of leaves and shoots was 30 cm × 40 cm × 40 cm, 5 plants per hole and 3 plants per hole, respectively.

After the emergence of Auricularia auricula, keep the soil moist and water at the right time. After each harvest, apply human feces and urine once in time, 500 kg per hectare, or 10 kg of urea, drainage and waterlogging prevention in time in the rainy season.

When harvesting the tender shoots, when the seedling height is 30mi 35cm, leave 3mur4 leaves to harvest the head tip. After that, two strong and exuberant lateral buds were selected to form shoots, and the rest were erased. After 2 shoots were harvested, 4 strong lateral buds were left to form shoots, and the rest were erased. During the peak growth period, 8 strong lateral buds can be selected to form shoots. Auricularia auricula vegetables should wipe off the buds at any time in the middle and later stages. At the end of harvest, two strong lateral buds can be left to form shoots.

Harvest leaves for cultivation, should build a frame on the vine, select the backbone vine, in addition to the main vine, choose the base of strong lateral buds into vines. When the backbone grows to the top of the frame, pick the heart. After picking the heart, strong lateral buds are selected from the base of the backbone of Auricularia auricula to form vines.

After sowing, the young leaves were harvested for 50 days, and the leaves were generally harvested every 15 days in the early stage, 15 days in the middle stage and 17 days in the later stage. When eating tender shoots, cut them with a knife or cut them with scissors, with a length of 10ml / 15cm and harvest them every 7-10 days. You can also cut tender shoots in the early and later stages and pick tender leaves in the middle.

The common diseases of Auricularia auricula are: Brown spot, also known as fisheye disease, red spot disease, snake eye disease, sun spot, etc., which can be sprayed at the initial stage of 72% Kelou wettable powder solution, or 68.75% easy dispersible granule 1000 times solution to control.
