After the pruning and planting of the seedlings is fixed, the buds below the main stem base are cut off at a height of 30 cm (branching zone), and three or more lateral buds or lateral branches with 3 cm to 5 cm spacing are selected for growth in the branch zone or above. As the backbone of the small canopy (the first canopy of the canopy), five were cut at a height of 40 cm to 50 cm.
Summer pruning In late May and late July, the following germination was cut off at the main branching branch every 15 days, and the remaining branching above the branching branch was cut short at the branch length 20 cm to promote secondary branching; The top branches (middle twigs) growing upwards were selected to have 2 to 3 branches (10 centimetres apart) in different directions of the trunk as the main branch of the small canopy, and were cut at 30 cm to promote secondary branching. Autumn fruit.
Soil fertility The new garden was planted with 100 grams of N and P compound fertilizers in each plant in early July, and 100-150 grams of urea per plant was planted in 2-year-old oysters in mid-April, and nitrogen was applied in early June. Phosphorus compound fertilizer 150 grams -200 grams, in mid-July applied nitrogen, phosphorus compound fertilizer 150 grams -200 grams. Method is to open the ditch at the outer edge of the crown 10 cm -15 cm deep, 30 cm long ditch, the amount of chemical fertilizer applied to the ditch, and the soil mix well sealed ditch irrigation. Autumn basal fertilization is carried out from late September to early October. Symmetrical pits are opened along the outer edge of the canopy. Pit length is 30 cm to 50 cm (depending on the size of the crown), and the pit depth is 30 cm. Each plant applies 2 kg of cake fat - 5 kg, goat manure 5 kg - 15 kg (depending on the age of the tree), diammonium 150 grams, mixed with the soil mix and seal pit, ready to irrigate winter water.
Foliar spray fertilizer for 2 years to 4 years The alfalfa plants are sprayed with auxin once in May, June, July and mid-August (leaf foliar, spray-applied, high-yield etc.), 30 kg to 50 kg per mu. Aqueous solution.
Timely pest prevention and control of aphids using 50% of monocrotophos 1000 times -2000 times liquid or 40% of omethoate 1000 times canopy spray; control negative muddy insects use 20% cypermethrin 2000 times - 3000 times liquid crown spray; prevent rust螨 Sulphur glue suspension 500 times liquid crown spray.
Irrigate in a timely manner The annual fertility period (April-September) irrigation 5 times, mu water intake of 50 cubic meters; winter water (in early November) acres of water intake of 70 cubic meters.
The cultivator turned the garden from May to August and tilled 4 times with a depth of 15 cm. In September, the garden was turned once, with a depth of 25 cm and a 15 cm under the canopy. The plant stem was not damaged.
Pruning in autumn In September, leggy branches, trunks, and canopy branches were removed from the plants.
The selection and application of Lentinus edodes strains is a relatively complicated technical issue. In addition to understanding the quality standards of the strains, users need to understand the age of different strains from 55 to 240 days (the time difference from cultivation to mushrooming). Up to 2-6 months), mushroom shape and temperature type (sensible temperature of mushroom can be divided into low temperature type 8 ℃ ~ 12 ℃, medium temperature type 12 ℃ ~ 16 ℃, high temperature type 18 ℃ ~ 22 ℃, 12 years a year The monthly average temperature changes between 2 ° C and 4 ° C), combined with the basic knowledge of applied technology such as the seasoning of mushrooms, can only choose the suitable high-yield stable bacteria.
