Embodiment 1

[0021] Embodiment 1, the preparation of cotton branch cutting rooting agent

[0022] Weigh the following substances: KI 0.005g, MnSO 4 4H 2 O 0.05g, HBO 3 0.009g, ZnSO 4 ·7H 2 O0.02g, IAA 20mg, KT 5mg, 6-BA 5mg, trace additives: VB 1 0.4mg, VB 6 0.4mg, inositol 100mg. The above substances were dissolved in 1 liter of distilled water for later use.

Embodiment 2

[0023] The rooting test of embodiment 2, cotton branch cutting

[0024] The cotton branch cutting and rooting agent prepared in test example 1 affects the rooting of cotton branches, and the specific method is: select a healthy and disease-free cotton branch with 2-3 true leaves, cut the base into a wedge shape of about 1 cm, and immerse it In the rooting agent prepared by example 1, soak for 24 hours. Cuttage is then inserted on the cotton soilless seedling cultivation medium in the plastic box for seedling cultivation (to facilitate root observation) (for this medium formula, refer to the patent "a kind of cotton soilless seedling cultivation substrate" of the Cultivation Room of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, patent application number : 03149367.X), the raffinate of used rooting agent is diluted 50 times and then poured on the above-mentioned seedling-raising substrate, and the plastic film insulation, moisture are cultivated,...

Abstract

The invention discloses a cotton bough cottage method and special-purpose root-growing agent for cottage, wherein each 1000mL of the water solution of the agent contains the following substances, KI0.004-0.02g, MnSO4*4H2O 0.017-0.085g, HBO3 0.003-0.012g, ZnSO4*7H2O 0.0043-0.035g, IAA 10-30mg, KT 1-10mg, and 6-BA 1-10mg. The powder preparation of the agent comprises KI, MgSO4*4H2O, HBO3, ZnSO4*7H2O, IAA, KT and 6-BA by the weight ratio of 4-20:17-85:3-12:4.3-35:10-30:1-10:1-10.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a cotton branch cutting method and a special cutting rooting agent thereof. Background technique [0002] In the cotton breeding work, the selection of new cotton varieties is finally obtained through the selection of high-quality single plants, and the selection of high-quality cotton plants mainly goes through the selection of multiple stages such as seedling stage, bud stage, flowering and boll stage, and boll opening stage. , and finally determine the excellent single plant. Since cotton is a cross-pollination crop, there are serious genetic variations in the seeds of excellent individual plants, so it is necessary for breeders to conduct pedigree selection for many years to obtain lines with similar traits to the selected individual plants. However, the application of cotton branch cutting technology can not only preserve excellent single plants, but also expand single pl...
