How to cultivate Auricularia auricula vegetable with high yield

Auricularia auricula (scientific name: Gynura cusimbua), also known as babbling, sunflower, tofu, purple horn leaves, chrysanthemum Panax notoginseng, perennial tall herbs, 1.5-2 meters high. Flowering and fruiting period is from September to October. Auricularia auricula vegetables are fed by seedlings, tender shoots or tender leaves, with tender and smooth texture and high nutritional value. Can be used for soup, stir-fry, hot food, cold, etc., its taste is fragrant, chewing like eating fungus generally crisp and refreshing, hence the name agaric dish.

Auricularia auricula is an annual vine of the sunflower family, its leaves are thick, elastic, taste very good, slippery taste, very similar to Auricularia auricula, so it is named Auricularia auricula. Auricularia auricula is also a green leaf pollution-free vegetable with high quality, high yield, safety and health care. It has wide adaptability, temperature-loving, heat-resistant and waterlogging-resistant, and has low requirements for soil texture. It can be planted except saline-alkali soil. It can not only be cultivated in the field, but also be planted in the courtyard economy. So how to cultivate Auricularia auricula vegetables to achieve high yield?

1. The sowing method of Auricularia auricula can be sown in spring, summer and autumn. Strip sowing is suitable for planting in the field, and hole sowing is better in the courtyard. There are two ways of sowing: one is to accelerate germination and soak the seeds in warm water for 3 days, remove them and clean them with clean water, cover them with a wet towel in a container, cover the seeds for 3 ~ 4 days under the condition of moisturizing and breathable, and gently mix them with hay wood ash when some of the seeds are white, so that the seeds are scattered and sow; the second is direct seeding, that is, 7 ~ 10 days after accelerating germination, dry seed direct seeding takes 10 ~ 15 days to complete the seedlings. The row spacing of strip sowing is 15 cm ~ 18 cm, the depth of ditch is 3 cm ~ 4 cm, the width of border is 1.2 m ~ 1.4 m, and the thickness of cover soil is 1.5 cm. Watering after sowing to keep the soil moist and grow seedlings. The seed used for strip sowing is 2.3 kg ~ 3 kg per mu, and 1.5 kg ~ 2 kg per mu for interseedling transplanting.

two。 The base manure for fertilization management is farm manure, livestock and poultry manure. Topdressing is applied with mature human and animal manure or urea dissolved water. Topdressing once after harvesting for 2 ~ 3 times, and so on.

3. Control of diseases and pests in general, agaric vegetables do not need to be controlled by pesticides, and Spodoptera litura is harmful in special years. If there are many small eyes at the tip of the tender leaves, pyrethroids can be sprayed once at the 1st to 2nd instar, otherwise there is no need for drug control. There is also a common brown round spot disease, which does not need chemical control, mainly to ensure an adequate supply of fertilizer and water, plant growth is exuberant, and far away from the seed land can be avoided. In addition, seedling rot and stem rot can be seen in a few plants in the field, which can be controlled by pulling out the diseased plants. Root-knot nematode disease may also occur in continuous cropping of Auricularia auricula on sloping highland, and the implementation of crop rotation can reduce or avoid the disease.

4. The timely harvest of Auricularia auricula is mainly to feed on tender stems. Pick the tender stem with leaves and put it on the market during harvest. The seedlings were evenly distributed when the seedling height was 18 cm ~ 20 cm, and the tender stems and leaves of the remaining plants were listed on the market at the same time; the axillary buds of the later plants were harvested again and again until October. Generally, the yield per mu can reach 3500 kg ~ 4000 kg. The seeds mature from green to black in November.

How to improve the seed germination rate of Auricularia auricula?

Because the seed shell of Auricularia auricula is thick and hard, dry seed sowing often takes more than ten days to germinate one after another. the following methods are generally used to improve its germination rate:

1) scratch the seed coat and sow seeds.

2) soaking seeds to accelerate sprouting, then sowing seeds. That is to say, soak the seeds in 25-30 ℃ warm water for 1-2 days, then use about 30 ℃ to accelerate germination, sow the seeds after whitening, and complete the seedlings after a week.
