Quick betula alnoides seedling raising method based on flower arrangement mud serving as cutting substrate

Abstract

The invention discloses a quick betula alnoides seedling raising method based on flower arrangement mud serving as a cutting substrate. The method comprises the following steps of cutting the flower arrangement mud into rectangular cutting blocks and pruning branches of betula alnoides into cuttings for hormone treatment; inserting the cutting branches of betula alnoides into the cutting blocks; regularly and randomly lifting the seedlings for observation, and transplanting nursery stocks when the portions, extending out of the flower arrangement mud, of root systems of the nursery stocks are 3 cm in length and are slightly lignified. According to the method, the flower arrangement mud is used as the cutting substrate and has the advantages that water is effectively maintained, the permeability is high, rooting is facilitated, multiple robust roots grow out, and there is no need to frequently perform watering. Compared with betula alnoides based on cuttage in a traditional substrate, the method has the advantages that the cutting rooting time of the flower mud is advanced by 10 days or above, and the roots are strong and not rotten. After the new roots grow out, the new roots can be transplanted together with the flower mud blocks to avoid the damage caused by digging out the traditional soil substrate to the root systems. The nursery stocks with the flower mud can be directly loaded into boxes and cases, the root systems are not damaged, the freshness is kept, the cost is low, and carrying and conveying are facilitated.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a rapid seedling raising method for Betula chinensis based on flower cutting mud as a cutting substrate. Background technique [0002] Southwestern birch (Betula alnoides) is a tall deciduous tree belonging to the family Betula, and is a precious fast-growing timber tree species in tropical and subtropical regions. Its trunk is straight and round, and the wood has excellent characteristics such as moderate density, beautiful texture, no warping or cracking, and easy processing. It is widely used in high-end architectural decoration and high-end furniture production, and has high economic value. Moreover, Betula has strong adaptability, resistance to barrenness, and rapid growth. It is one of the main species of water conservation forest (natural secondary forest) and has important ecological value. But the resources of good varieties are very scarce. With t...

Problems solved by technology

At present, the traditional method of sowing and raising seedlings is mainly used in the production of Southwest Betula to cultivate afforestation seedlings. Because the seeds of Southwest Betula are small, the sprouts grow slowly, are weak, and are susceptible to infection and die in pieces. The management is labor-intensive and time-consuming, and the seedling cultivation cycle is long; , the inter-species differences are large, the differentiation is obvious, the excellent traits of the female parent cannot be maintained, the stand quality is not high, the volume yield is low, and it cannot meet the needs of intensive and industrialized development; traditional cuttings generally use red core soil and other substrates as the propagation substrate , high cost, poor water retention, easy-to-contaminate roots, long rooting time, etc.; group seedling cultivation requires high technology, long seedling time, seedling transplanting survival rate, and high cost
