Sand black pine big seedling transplanting method

Abstract

The invention discloses a sand black pine big seedling transplanting method, and relates to the technical field of black pine transplanting. The method comprises the following steps that transplantingis conducted from October to November or from March to April; preparation is conducted, wherein the to-be-transplanted seedling direction is marked, branches are trimmed, a trunk is wrapped, and thesize of a provisonal planting hole is determined in advance; seedling lifting is conducted, wherein root systems are trimmed after mechanical digging is conducted to cut roots and lift seedlings; sackpieces are put into a shaping device, nutrition soil which is about 1 / 4-1 / 3 of the size of the shaping device and is special for black pine transplanting is loaded in the shaping device, and a vent pipe arranged at the bottom stretches out of the earth surface; the trunk direction is adjusted according to the mark, the trunk is put into the shaping device, the nutrition soil spacial for black pine transplanting is prepared from, by volume, 40-50% of planting soil, 20-30% of plant fiber, 10-20% of branch material fermented substrates, 3-5% of bentonite, 3-5% of citric acid residues, 5-10% of citric acid-production wastewater, 1-3% of organic fertilizer and 0.05-0.1% of a water-retaining agent, maintenance management in the provisonal planting period is conducted, after new roots sprout, and field planting and maintaining after field planting are conducted. Accordingly, aiming at black pines planted in sand, the method has the advantages that soil fixation and sand retention effects aresignificant, stable soil ball formation is facilitated, and the new root sprouting speed is high.

Description

technical field [0001] The invention relates to the technical field of black pine transplanting, in particular to a method for transplanting large black pine seedlings in sandy land. Background technique [0002] Black pine is resistant to drought and barrenness, sea fog, sea tide wind, windbreak, sand fixation, and water and soil conservation. It is an excellent pioneer tree species in coastal sandy coastal forests. Due to the large pores between the particles of the sandy soil, the water permeability is good; the organic matter decomposes quickly, accumulates less, and the nutrients are easily wetted. With the metabolism of plants and the change of phenological period, the litter layer is gradually formed on the surface, and the litter layer is decomposed into the main source of soil organic matter under the action of microorganisms, gradually changing the physical and chemical properties of the shallow soil on the surface. It can be found from the anatomical surface of t...
