Problems solved by technology

[0003] In order to overcome the deficiency that the existing artificially cultivated Korean pine seedlings cannot bear fruit, the present invention provides a method for plant hormones to induce early fruiting of Korean pine saplings, which not only advances the picking period of Korean pine seeds, but also greatly improves the quality of Korean pine seeds.

Embodiment Construction

[0010] The present invention will be further explained below in conjunction with specific examples.

[0011] A method for phytohormones to induce early fruit setting of Korean pine includes the following steps:

[0012] (1) Selection of nursery stocks: Choose high-quality nursery stocks that are robust, normal in color of needles, free from pests and diseases and mechanical damage;

[0013] (2) Pretreatment of seedlings: before afforestation, soak all seedling roots in clean water for 5 hours to ensure that the seedlings absorb enough water before planting;

[0014] (3) Land preparation and afforestation: adopt spring afforestation method. When planting afforestation, first plan to remove the turf of the seedling hole, the hole diameter is 35cm, and the depth is 20cm. The seedlings are planted in the hole and the root system is stretched and covered with soil.

[0015] (4) The configuration of the fruit-setting induction solution: choose gibberellin and ethephon as the regulating hormo...

Abstract

The invention provides a method for inducing a Korean pine to fruit in advance by plant hormones. The Korean pine is a main forestation tree variety of mountain areas of Northeast of China. In recent years, the market demanding quantity to Korean pine seeds is greater and greater so that the Korean pines are excessively picked in successive years and wild Korean pine trees are seriously damaged. The Korean pine at a juvenile stage does not blossom and fruit; and after the juvenile stage, the Korean pine can blossom and fruit at a sexual maturity stage (namely an adult stage). According to the method disclosed by the invention, on the basis of comprehensively understanding main factors which influence Korean pine fructification heredity, derivation, external environments and the like, gibberellin and ethephon are used as the plant hormones to induce and accelerate Korean pine forestation seedlings to fruit in advance.

Description

Technical field [0001] The present invention relates to a method for hormone-induced plant setting, in particular to a method for plant hormone to induce early setting of Korean pine. Background technique [0002] Red pine (Pinus koraiensis Sieb.et Zucc.) is the main afforestation tree species in the mountainous area of ​​northeast my country, and it is also one of the important and precious timber species in my country. It has high utilization value from wood, seeds to bark, leaves and roots. In recent years, due to the substantial reduction of natural forest resources of Korean pine, although the early planted Korean pine plantations have entered the fruiting period, the yield is not high. In recent years, the market demand for red pine seeds has increased, so over-picking has caused serious damage to wild red pine trees. The juvenile period of Korean pine cannot bloom and bear fruit. Only after the juvenile period is over and reaches the sexual maturity stage (that is, the ad...
