Soil treatment, mushroom planting and seedling cultivation of Siraitia grosvenorii series

1 Selection of Garden: according to the conditions of the biological characteristics of Siraitia grosvenorii, the newly opened orchard should be built on the slope with the elevation of 300-500m, the soil being yellow and red loam, fertile, thick soil layer, well preserved miscellaneous trees and secondary forest around 2 Reclamation of the garden: the garden is usually built in August to September The garden is built on a sunny day and set on fire in September to October Because it's a hot season, and it's sunny Firewood is easy to dry, and it's easy to burn the ground, burn all the leaves of firewood, eliminate the diseases and pests on the ground, and weathered the soil After October, the ground can be dug After a winter's exposure and weathering, it can accelerate the soil ripening, improve the physical and chemical properties of the soil, and improve the soil fertility During the reclamation, it is generally about 8 inches deep The roots of the trees are removed, the stumps are dug, and the grass roots and stones are removed Before the next year's planting, the probiotics liquid can be sprayed with yifuyuan for cultivation, which is 3-5kg per mu The soil is improved and the soil vitality is improved After that, the soil can be planted once When planting Siraitia grosvenorii, we must consider the water source of the garden If the water source is far away, a reservoir should be built beside the garden to facilitate fertilization and drought resistance The slope of the garden is small and the drainage is not good We should open the wow ditch and the ring ditch for drainage and create the soil conditions suitable for the cultivation and growth of Siraitia grosvenorii Planting technology of Siraitia grosvenorii 1 Time of planting and stumping: the time of planting and stumping in new garden and old root is generally about one week before and after Qingming Dynasty, and the time of planting tissue culture seedlings can be postponed to the end of rain planting 2 Before planting, carefully select the seeds (the robust ones with intact buds, many roots, tender seeds and no pests) and prepare pig and cow dung as the base fertilizer The method of applying pig and cow dung organic fertilizer to the geographically thoroughly decomposed pig and cow dung after maturity is the best: (1) fermentation and composting method: the total amount of organic raw materials such as rice bran, wheat bran, straw powder, pig and cow dung is 500-1000 kg, adding 3-4 kg of biological fermentation liquid, adding a proper amount of well water (depending on the degree of dry and wet of raw materials, the amount of water accounts for 30% - 35% of the total amount of compost), adding biological fermentation liquid into the water, mixing with raw materials, composting and fermentation, two weeks later, there is koji flavor The fermentation was successful when the taste or white hyphae appeared; 100-200kg was applied per mu, or according to the status of soil fertility (2) the compost is fermented once a week or so, and then it can be fermented Generally, the fermentation is completed in 15-20 days After successful fermentation, the organic fertilizer does not burn the seedlings, completely killing the harmful bacteria and eggs in the feces The nutrient composition of the fertilizer is improved, the fermentation time is short, the operation is simple, and the cost is low 3 When planting, firstly, according to the row spacing of 5 × 6 feet, open the hole, 160-200 holes per mu, 3-4 Jin of fermented high-quality pig and cow manure organic fertilizer and soil are mixed evenly, and then the plant is planted obliquely on the top, with the bud head facing up, covered with fine mud for 2-3 parts thick, to avoid the sun exposure to the bud head, it is better to plant multiple double plants, less single plants, 300-360 plants per mu, if it is a perennial root, it will be done when the plant is opened To clean up the sick, insect, and rigid plants, and make up for the lack of stumps, so as to ensure the whole seedlings 4 Treatment method of laoru: after 4 years of planting, the roots of luohanguozhongru have been growing for many years, and the hair of the roots is aging When the roots are opened, part of the roots should be cut off or the whole roots should be cut off in an inch or so If the roots of laoru are more than 7 years old, except for the roots, the old cortex of the pieces of Ru should be cut off with a knife, and then they should be soaked with the mushroom liquid of yifuyuan before planting At the absorption temperature, promote the germination of long roots Strengthening the management and protection can prolong the bearing period and increase the output 5 Planting of tissue culture seedlings: the planting specifications and the number of plants per mu are the same as above, but excellent strains are selected during planting After virus-free and disease-free seedlings are refined, strong seedlings with well-developed roots and many fibrous roots are planted During planting, the roots are naturally extended, backfilled, compacted and drenched with fine soil It's best to plant with plastic mulch It's like planting pepper in early spring.
