Embodiment 1

[0034] A method for growing seedlings by cuttings of rubber trees in the field, comprising the following steps:

[0035] Step 1, the establishment of the seedling bed, the seedling bed includes rubber tree ear picking area, water storage area and cutting area;

[0036] Step 2, preparation and disinfection of the seedling-raising substrate, the seedling-raising substrate is a mixture of river sand, peat soil and raw red soil;

[0037] Step 3, cuttings preparation and cuttings processing;

[0038] Step four, cutting;

[0039] Step five, post-planting management, including temperature and humidity management in the cutting area, water storage area management and pruning in the ear garden;

[0040] Step six, bagging and transplanting.

[0041] Further, the establishment process of the ear-picking area in the first step is to plant two rows of rubber trees with a row spacing of 2.5m×1m, and the planting time is June, and in September of the following year, saw the rubber trees t...

Abstract

The invention relates to the technical field of plant propagation, and in particular relates to a method for raising seedlings by cutting for hevea brasiliensis in a field. The method includes the steps of establishment of a seedling raising bed, preparation of a seedling raising substrate and disinfection, preparation of cuttings and treatment of the cuttings, the cutting, management after the cutting and bagging transplanting. When the method for raising the seedlings by the cutting for the hevea brasiliensis in the field provided by the invention is used, a cutting rooting rate is significantly improved, an average cutting rooting rate achieves 80%, a root system of the cutting seedlings is well developed, and has more and developed lateral roots and hard texture, and a transplanting survival rate achieves 98%; according to the method for raising the seedlings by the cutting for the hevea brasiliensis provided by the invention, after the cutting is performed, artificial watering isnot needed, other equipment is not needed for heating, shading and light-filling treatment, so that the production costs are greatly reduced; and the method closely combines a cutting orchard with a cutting area, thereby greatly improving land utilization efficiency.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for cultivating rubber tree seedlings by field cutting. Background technique [0002] Rubber tree (Hevea brasiliensis) is a perennial tree belonging to the family Euphorbiaceae, and it is the main source of natural rubber because of its high yield, good quality and easy access to latex. At present, in the production of natural rubber, old budding clones are widely used as rubber planting materials because they can maintain a relatively high yield of mother tree trunk rubber, but they grow slowly, have short economic life, poor stress resistance, and small adaptability. To a certain extent, it restricts the development of natural rubber industry. In addition, the growth, stress resistance and rubber production of budding clones are affected to varying degrees by the rootstock, so that the individual clones cannot maintain the excellent traits of the original cl...
