Tribute, also known as dried moss, loud vegetables, mountain thorns and moss. The color is light green, the texture is refreshing, the taste is like jellyfish, and the edible value is extremely high. It is a green leafy vegetable, which is made by peeling, splitting and drying the stems in autumn. In Suining county, Chinese milk vetch has been planted for more than 2000 years. It is a precious vegetable in the north temperate zone, belonging to Compositae, Lettuce and Panicum.
It can be used to cook vegetables, stew soup, prepare various vegetarian dishes, and make them into north-south flavors, which taste like jellyfish and have a unique style.
The cultivation of tribute vegetables is as follows:
1, soaking seeds to accelerate germination.
Before sowing, the seeds should be germinated at low temperature. The seeds should be soaked in cold water for 3-4 hours, put into a cloth bag and refrigerated in the refrigerator for about 2 days before germination.
2. Seedbed preparation.
Choose fertile and arid fields with convenient irrigation and drainage as seedbeds, use high border drains for drainage in rainy season, and use semi-submerged border for water conservation in dry season. After sowing, cover with fine soil or decomposed fine manure, and finally cover with straw, pine wool, etc.
3. Seedbed management.
After sowing, watering can is often used to keep the surface of the border moist, so as to prevent it from being too wet, and to avoid the wound caused by exposing the roots and dropping seedlings due to water scouring the seedbed, which will induce sudden collapse and sudden collapse. Pull weeds with plastic film in time after emergence. The seedbed should be pre-treated with spray water (A, B, Jing, Luo, propamocarb+hymexazol, propamocarb+Dithiouron) to prevent the seedling from withering and collapsing.
Note that hymexazol should not be used in high concentration. High concentration or repeated use will inhibit the growth of aboveground parts. When raising seedlings, mancozeb, thiophanate-methyl and chlorothalonil can be sprayed to control downy mildew and rust, and abamectin or cypermethrin can be used to control pests. Generally, fertilization is not needed during seedling stage, and low concentration organic liquid fertilizer can be used to cultivate seedlings with weak growth potential.
4. transplantation.
Soil preparation before transplanting, with the spacing of 16 ~ 20 cm, leaving seedlings per mu16 ~ 26,000 plants, and thoroughly watering the planted living trees.
5. Fertilizer and water management.
After survival, properly control watering and squat for 2 weeks to promote rooting. Timely intertillage and weeding, apply ammonium nitrate, phosphorus and potassium fertilizer (26∶8∶5) 10kg, squat and raise seedlings, and water frequently to ensure the growth of seedlings; When the leaves are 7-8, combined with scarifying and topdressing, 20 kg of ammonium nitrate and 26 ∶ 8 ∶ 5 phosphorus and potassium fertilizer are applied per mu to promote roots and seedlings.
When the heart-shaped leaves are flush with the rosette leaves, apply ammonium nitrate, phosphorus and potassium fertilizer (26∶8∶5) 10 kg per mu. After the stem is elongated, 20 kilograms of potassium sulfate is applied in combination with watering mu. Spraying 0.3% potassium dihydrogen phosphate 1 ~ 2 times in combination with disease prevention when the stem begins to swell.
Appropriate reduction and fertilization in interplanting vineyards can be flexibly grasped according to the growth. During the growth period of tribute vegetables, water them frequently, especially after fertilization, to prevent the roots from burning out. At the same time, we should pay attention not to wet or excessively apply nitrogen fertilizer, and stop watering 5 ~ 7 days before harvesting, otherwise it will crack easily and reduce the quality.
6, pest control.
Tributes are prone to downy mildew, rust, liriomyza sativae, aphids, thrips and other diseases and insect pests, especially in the seedling growth period, which is prone to diseases and insect pests, leaf atrophy and slow growth. It can be controlled by thiophanate-methyl, mancozeb, chlorothalonil, dimethomorph, abamectin, imidacloprid and thiamethoxam.
