Brown Plum is native to the United States. In order to speed up the breeding of brown plum seedlings, our researchers have explored a seedling technique that was planted that year, grafted that year, and that year it was bred. Its main measures are as follows: Dimmable Light Switch,Double Dimmer Switch,Dimmer Switch Led Lights,Double Control Dimming Switch Hangzhou Lingjun Technology Co.,Ltd , https://www.lingjunelectrical.com
1, the choice of seedlings. Choose a sandy loam with convenient transportation, complete irrigation and drainage facilities, and fertile soil. Do not use saline-alkali land, low-lying land, clay land, and heavy land.
2, seed processing. Take nectarine as rootstock. There are two kinds of rootstock seed processing methods: (1) no sand: Select seeds, drying, no soaking in a month and a half, remove and control the water, direct sowing. (2) Sand: no month soak the selected seeds for a day and night, remove and control the clean water, use 50% carbendazim for 1000 times, mix sand with wet sand (the moisture content of the sand will become a group, a touch. Scattered is appropriate). Shazanggou is better in the shade, with a depth of 30 cm. The bottom of the trench is covered with 5 cm of sandy soil, and the mixed seeds are poured and the top is covered with 10 cm of sand. Half a month later, check regularly to see if the temperature and humidity are the same. When the seeds are 7% white, they can be sown.
3, soil preparation. For seeds that are not sandy, after soaking, they are sowed before freezing (Yuan); seeds are sowed in February. Miaoyao applied 5,000 kilograms of high-quality farmyard fertilizer per 666.7 square meters, 25 kilograms of phosphate fertilizer, and 25 kilograms of potash fertilizer, and used potassium-phosphorus-phosphorus-phosphorus for soil treatment to prevent and control underground pests. After the land is leveled, the width of the plant is 2 meters. The planting distance is 50 centimeters and the north and south direction. Before the next species, it is sufficient to sow the seedlings with a depth of 4 cm, a turtle shape, and a mulch.
4, seedling management. When the film temperature exceeds 35°C, break the film in time to prevent burning. After the seedlings emerged from the film, a small amount of fertilizer was applied to the fertilizers in quick succession, timely watering, cultivating and weeding, removing lychee, and controlling pests and diseases.
