Method of efficient seedling growing for pear trees

Abstract

The invention discloses a method of efficient seedling growing for pear trees. The method comprises following steps: A. building a pool in a cultivation greenhouse, wherein the bottom and walls of thepool are covered by plastic film, the pool is filled with water and nutrient solution is added; B. laying cystose on the water surface; C. cutting old branches of pear trees, keeping 2 to 3 leaves onthe cut old branches, and inserting the lower ends of the old branches in the cystose and in the water; D. keeping the air temperature between 18 to 25 DEG C, humidity between 70 to 80%, covering thecultivation greenhouse with 75% sunshade net, after 30 days, 5 to 10 cm long white root hair coming out; E. field planting with nutrient soli in cultivation pots; F. after 30 to 40 days, transplanting the branches in a field planting greenhouse. By means of the above method, reliable guarantee is provided for the growth of pear tree seedlings; multiple times of transplanting shortens the cultivation period and the requirement of vegetative propagation is met; there is no need of stocks; the quality of pear tree seedlings is improved; the requirements of seedling growing is met and the methodcan be extended widely and scientific and reasonable cultivation means to make its cost low.

Description

technical field

[0001] The invention relates to a method for raising seedlings of fruit trees, in particular to a method for raising seedlings of pear trees with high efficiency, and belongs to the technical field of agricultural planting. Background technique

[0002] Traditionally, for the cultivation of pear tree seedlings, the cultivation method of grafting pear trees is generally adopted. When cultivating in detail, first cultivate one year to obtain the pear trees, and then graft them after the cultivation of the pear trees. The traditional method of cultivating pear tree seedlings , the process is relatively complicated and the cultivation cycle is long, and the whole process will take at least two years. However, with the development of fruit tree cultivation technology, the requirements for seedling quality are getting higher and higher. Seedlings must have branches, and their robust growth has become a difficult technical problem. Contents of the invention [00...

Embodiment Construction

[0015] Below in conjunction with specific embodiment, the pear tree efficient seedling raising method of the present invention is described in further detail.

[0016] The efficient seedling raising method of pear tree of the present invention comprises the following steps:

[0017] A. Build a pool in the cultivation greenhouse. The length of the pool is 8m, the width is 1m, and the depth is 0.25m. The bottom of the pool and the four walls are covered with plastic film to prevent leakage. Add water and nutrient solution to the pool, and add rooting at the same time agent and plant growth regulator, wherein the total amount of nutrient solution, rooting agent and plant growth regulator accounts for 0.1% of the water in the pool,

[0018] B. Lay the foam board on the water surface, the thickness of the foam board is 3~5cm;

[0019] C, cut the old branch of pear tree (preferably the old branch of more than one year), stay 2~3 leaves on the old branch that cuts off, the branch le...
