First, how to choose coffee seeds?

The selection of small-grain coffee requires that the fully mature fruit with 2 seeds, which is of the same size, normal shape and 2 seeds, should be picked from the excellent mother tree which has been put into production for more than 5 years, has strong growth and high resistance, and has more than 1kg per plant and is free of diseases and insect pests. Avoid direct exposure to the sun, dry for 1 or 2 days, pick out impurities and sow.

Second, the seedling method of coffee.

1. Nursery site selection

Close to water source, convenient transportation, loose soil, loam or sandy loam with good drainage and irrigation, paddy field or dry land with PH value of 6Mel 6.5 as nursery land, and close to coffee garden. After turning the soil 20 cm deep, hoing fine and removing stones, the ridge moisture is 1.2m wide and about 10m long, and apply rotten fine broken farm manure on the soil moisture, 3000 kg per mu, the soil and fertilizer are mixed and used as nutrient soil for bagging, the nutrition bag specification is 15 × 20cm, cut through the bag corner for drainage, put the nutrient soil into the bag, each row of 12 bags neatly placed, upright, each mu can put 60-70, 000 trees The shade branch column is planted according to the pile distance of 4 meters, and the shade density is 75% 85% with a height of 2 m. The nursery will be built with fence protection around.

2. Finishing and sowing of budding bed.

The nursery land that has been hoed and fertilized is spread out according to the spacing of 50cm, the soil moisture width of 1.2cm and the ridge moisture of 15cm to 20cm high. After disinfecting the soil with carbendazim, add 5mm 10cm thick river sand. Fubang Village planted 7963 new varieties, about 5000 seeds per kilogram, soaked in 40 ℃ 45 cm warm water for 24 hours, and sowed the seeds evenly on the sand bed so as not to accumulate. The sowing rate is 0.5ml 0.6 kg / m2, which is pressed into the sand with a plank and covered with 1ml 2cm of river sand, then covered with straw and watered thoroughly. The seeds were unearthed 80 days after sowing, and the seeds should be watered regularly before being unearthed to prevent drought, and the grass should be uncovered in time after the seedlings were unearthed.

3. Seedling management and transplanting nutrition bag

Pest control should be carried out before transplanting and bagging. Carbendazim and methyl thiophanate should be used to control seedling blight and dimethoate should be used to control diseases and insect pests. When the cotyledons of young seedlings are fully unfolded, they can be bagged. Soak the seedlings with water before pulling out the seedlings, reduce the mechanical damage to the roots of the seedlings, select small seedlings with stable cotyledons and strong seedlings, hold 10 cm of water in containers such as buckets or pots, put the seedlings neatly into the containers for preservation, and drench the nutrition bags full of nutritious soil with water before transplanting seedlings. After the seedlings are inserted into the nutrition bags, the roots are required to be straight. Root water is poured immediately after planting. During the nursery period, attention should be paid to the removal of weeds and prevention of diseases and insect pests. Human and animal feces and urine 2Mel were applied three times, poured with water at the proportion of 1:3, and foliar spray of 0.5% Yunda 120. When the plant height was 15 cm, 5 pairs of true leaves could be transplanted, and the seedlings should be refined for 3 weeks before transplanting.

All right, that's all the editor wants to share with you. At present, there is a large demand for coffee in the market, and there are many people who make money from planting, but when selecting seeds, we still have to pay attention to the selection of more than 5 years of production, robust growth, high resistance, a single plant to produce dried beans more than 1kg, excellent seeds free of diseases and insect pests, so that the coffee is of higher quality.
