Embodiment Construction

[0011] 1. a method for cultivating catalpa seedlings is characterized in that comprising the following steps:

[0012] (1) Raising catalpa seedlings: choose fertile fields with moderate soil humidity and good air permeability to raise seedlings. Before sowing, apply 1200 kg of decomposed pig manure per mu, plow 25 cm deep, start sowing in mid-April, sow 1 kg per mu, sow 2 cm deep, and sow Evenly, cover with velvet soil with a thickness of 1.5mm after sowing, water properly after sowing, subject to soaking the surface soil, plant reasonably densely after germination, remove young and weak seedlings and diseased seedlings, keep 5 seedlings per square meter, and manage daily Pay attention to weeding at the time, and use it after one year of cultivation;

[0013] (2) Scion: The scion must be of good variety. When the catalpa tree has not germinated after spring, cut the scion. The scion should be a 1-year-old branch with a thickness of 0.5cm. The scion is about 30cm long. There mu...

Abstract

The invention discloses a catalpa bungei seedling raising method. By virtue of multi-year planting experiences and reasonable collocation of all growing processes, the invention discloses a catalpa bungei seedling raising method. The catalpa bungei seedling raising method comprises the steps of raising seedlings, ingrafting scion and grafting. According to the catalpa bungei seedling raising method, based on the prior art, a seedling raising mode of grafting catalpa bungei to catalpa stock is adopted in catalpa bungei seedling raising; in grafting, naphthylacetic acid and a bactroban wound healing paste are adopted to treat a grafted part, and meanwhile a greenhouse temperature-controlled pot culture grafting method is adopted to strictly control the environment temperature and humidity, so that a favorable growth environment for grafted plants is ensured; by virtue of the catalpa bungei seedling raising method, seedling raising is rapid, and the survival rate in grafting is high.

Description

technical field [0001] The invention relates to the field of nursery stock breeding, in particular to a method for growing catalpa seedlings. Background technique [0002] Catalpa is one of the precious timber tree species in China. It has good material, wide application and high economic value, and ranks first in the hundred trees. The problem to be solved urgently at present, catalpa root grafting catalpa is the effective method of speeding up catalpa seedling propagation at present. [0003] Existing technology is only based on the grafting experience in the past when dealing with Catalpa catalpa on catalpa anvil and lacks scientific implementation methods, which often causes problems such as low survival rate and long seedling cultivation period. Contents of the invention [0004] The purpose of the present invention is to provide a method for growing seedlings of catalpa by grafting catalpa on catalpa with high survival rate. [0005] In order to solve the problems ...
