The breeding of coffee is mainly useful for seed propagation. Good seeds are the basis of strong seedlings and high yields. The fruit size of the offspring and the number of fruits on the lateral branch nodes tend to be maternal, with high productivity and good mother trees. The descendants are also more prolific, so the seeds should be collected into full-fledged and full-fledged fruits in the full fruit period. After the fruits are selected, the peels and pulp are removed in time to remove the pulpy gums adhering to the seeds, and then rinsed with clean water. In a cool and ventilated place, avoid sun exposure and air for 1-2 days.
l. Choose nursery land close to the water source, convenient transportation, loose soil, deep loam or sandy loam with good soil and irrigation, paddy field with PH value 6-6.5 or dry land, and close to the coffee garden. Deeply plow 20-30 centimeters deep, remove the stones and remove the stones. The width of the ridges is 1 to 1.2 meters long and about 10 meters long. The smashed farmyard manure will be applied to the sorghum at 3000 kilograms per acre. The soil and fertilizer will be mixed. After being used as a nutrient soil for bagging, the nutrition bag has a specification of 15 20 cm. The bag corner is cut to facilitate drainage. The nutrient soil is put into a bag. Each row of 12 bags is neatly placed, upright, and can be placed 6 per acre. - 70,000 trees, shaded by 4 meters of planting branches, 2 meters high shade density of 75-85%, four weeks need to set up fence protection, nursery is completed.
2. The preparation and seeding of the precipitating bed will be 50cm in pitch, 1.2cm in width, 15-20cm in height, and 5-10% in height. After sterilizing with carbendazim, add 5-10. Centimeter thick Jiangsha can be, to help villages plant 7963 new varieties, about 5,000 seeds per kilogram of seeds, soaked in warm water at 40-45 °C for 24 hours, after the seeds are evenly sowed in the sand bed, not suitable for accumulation The seeding rate is 0.5-0.6 kg/m2, which is pressed into the sand with wooden planks, covering 1-2 cm of Jiangsha, and then covered with straw on the surface and poured with water. 80 days after sowing, the seeds were unearthed and watered regularly before being excavated to prevent drought. The seedlings were uncovered immediately after unearthing.
3. Management of seedlings and transplanting of nutritional bags Before transplanting and bagging, pest and disease prevention should be carried out. Carbendazim and thiophanate-methyl should be used to prevent and control seedling blight, and dimethoate should be used to prevent and control pests. When the cotyledon of seedlings is fully expanded, Bagging. Before the emergence of the seedlings, it should be soaked with water to reduce the mechanical damage to the roots of the seedlings. Select the stable and robust seedlings of the cotyledons. Use a container such as a bucket or pot to hold the water for 10 cm. Store the seedlings neatly in the containers to preserve the freshness. Fill the nutrients before inserting the seedlings. The nutrition bag was soaked with water. After the seedling was inserted into the nutrition bag, it was required to be straight. Root water is poured after planting. During the nursery, we must pay attention to removing weeds and preventing pests and diseases. We must apply 2-3 times of human urine and excrement, dilute and pour water in a ratio of 1:3, and spray once with 0.5% of Yunda 120 foliar, when plant height is 15 Cucumber true leaves 4-5 pairs can be transplanted, transplanting before 2-3 weeks of hardening seedlings.
