High-efficiency environmental-friendly bare-root transplantation method for plant seedlings

Abstract

The invention relates to a high-efficiency environmental-friendly bare-root transplantation method for plant seedlings, which is characterized in that the method comprises the steps of 1) using Pafcal as transplantation medium and soaking with water for future use; 2) selecting annular cutting seedlings or annular sowing seedlings which are consistent in growth vigor and full in plant type as plant materials; 3) performing root system medium treatment on the plant materials, washing away residue medium on root systems, trimming branches, picking leaves and pruning the root systems; 4) planting the treated plant materials in Pafcal according to a standard of 4-6 plants for common vine plants, 3-4 plants for bushes or small trees and 3-5 plants for herbaceous plants; 5) when new roots do not grow at an early stage, keeping leaf surfaces to be wet, taking sunshade and cooling measures when indoor temperature is higher than 35DEG C and illumination intensity exceeds 40000lx, and performing foliage application after new roots grow; 6) when the surface of the entire plant medium is full of the root systems of the cutting seedlings and the entire nutrient pot is full of plant branches and leaves which fully cover the plant medium, taking out the seedlings. The high-efficiency environmental-friendly bare-root transplantation method for plant seedlings provided by the invention has the advantages of short period, simplicity and convenience in operation, high efficiency and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation. More specifically, it relates to a high-efficiency and environment-friendly bare-root transplanting method for plant seedlings. Background technique [0002] At present, the transplanting of seedlings is mainly based on transplanting with soil. Although there are reports of bare root transplanting, the so-called bare root is actually just an incomplete soil ball, which still contains part of the soil, and is not a true bare root. Roots, when transplanted with these two transplanting methods, although the survival rate of seedlings can be improved, there are still the following deficiencies: (1) The roots are more or less with some permanent soil, and the risk of soil carrying diseases and insect pests is relatively high. It is not conducive to the soilless export of seedlings; (2) The planting substrate is loose and easy to fall off, and the water retention is poor, which is not conduc...

[0002] At present, the transplanting of seedlings is mainly based on transplanting with soil. Although there are reports of bare root transplanting, the so-called bare root is actually just an incomplete soil ball, which still contains part of the soil, and is not a true bare root. Roots, when transplanted with these two transplanting methods, although the survival rate of seedlings can be improved, there are still the following deficiencies: (1) The roots are more or less with some permanent soil, and the risk of soil carrying diseases and insect pests is relatively high. It is not conducive to the soilless export of seedlings; (2) The planting substrate is loose and easy to fall off, and the water retention is poor, which is not conducive to long-distance transportation; (3) In order to improve the survival rate of transplanting, seedlings are generally transplanted on rainy days, before nine in the morning or in the afternoon After four o'clock, the time limit is relatively large
