Mulberry seedlings
1, mulberry seedlings out of the nursery is the last link. Grafting seedlings must be under the premise of ensuring the quality of seedlings, do a good job digging, grading, falsification, quarantine and packaging and transportation work to prevent seedlings mixed and reduce the quality of mulberry seedlings.
2. Dig up the seedlings to ensure that the mulberry roots are intact and the seedlings are not damaged. Generally in the autumn deciduous year of spring sap flow, soil freezing should not dig. When digging seedlings, prevent the variety from mixing. After digging the seedlings, rootstock seedlings, disease-infested seedlings, etc. shall be removed, and grading shall be carried out according to the mulberry seedling grading standard and be bundled separately.
3, after the seedlings are dug up, they should be planted immediately, and the survival rate after planting is high. However, if they cannot be planted in the short term, they should be stacked in the house or covered with straw in outdoor areas to prevent the seedlings from being exposed to the sun, rain and frostbite. If the planting time is longer, planting should be performed to avoid seedlings drying out. The method of planting is to dig false-grooves first, which is generally 50 cm wide and 50 cm deep. The side of the ditch is a 45-degree slope. Then the saplings are placed on a slope, straightening the roots, and finally buried with soil. Seedlings should be 1/3 to 1/2 buried in the soil. Drainage ditch is set around to avoid water accumulation and cause rot. For long-distance transportation of seedlings, they must be properly packaged to ensure seedling quality. According to the size of the seedlings, each bundle of 100 strains is affixed with a label bearing the variety, quantity, and rank, and the mulberry seedlings are quarantined. During transportation, light transport should be done to avoid rain and sunlight, so as to ensure the quality of the shipment of mulberry seedlings.
