Embodiment 1

[0015] A method to promote the growth of Dactylis:

[0016] Matrix formula:

[0017] Element Dosage (parts by weight) coconut brick 35 copies soil 65 copies

[0018] Preparation:

[0019] Directly sow the duckweed seeds in the nutrient bowl with the matrix installed, sow 1 seed per nutrient bowl, cover the upper layer with 1.0-1.2cm of matrix, press lightly, place the nutrient bowl on the seedbed, add water to the seedbed to 1.5-1.8 cm from the bottom of the nutrient bowl At cm, the water completely infiltrates the substrate. Before emergence, add water at any time to make the moisture content of the substrate 35-40%. At the three-leaf stage, it needs to be transplanted into a flowerpot for continuous cultivation for one month, and then sprayed with water every 7 days as a control. plant. Described substrate is to get the soil of formula quantity to carry out pre-treatment, and described pre-treatment is to get soil and pulverize 20 mesh sieves,...

[0021] A method to promote the growth of Dactylis:

[0022] Matrix formula:

[0023] Element Dosage (parts by weight) coconut brick 50 copies soil 50 copies

[0024] Preparation:

[0025] Directly sow the duckweed seeds in the nutrient bowl with the matrix installed, sow 1 seed per nutrient bowl, cover the upper layer with 1.0-1.2cm of matrix, press lightly, place the nutrient bowl on the seedbed, add water to the seedbed to 1.5-1.8 cm from the bottom of the nutrient bowl At cm, the water completely infiltrates the substrate. Before emergence, add water at any time so that the moisture content of the substrate is 35-40%. After cultivation to the three-leaf stage, it needs to be transplanted into flower pots for continuous cultivation for one month, and then spray at a concentration of 60ppm every 7 days. Naphthaleneacetic acid solution. The matrix is ​​pre-treated by taking the soil of the formula quantity, and the pre-treatment is to take the s...

Abstract

A method for promoting the growth of orchardgrass includes the steps of directly conducting hill-seedling on one orchardgrass seed in each feeding block with a substrate, covering the upper layer of the seed with the corresponding substrate with the thickness of 1.0-1.2 cm, conducting gentle pressing, putting the feeding blocks in a seedling bed, adding water to the seedling bed until the water reaches the position, 1.5-1.8 cm above the bottom, of each feeding block and completely wets the corresponding substrate, supplementing water at any time before the seedlings emerge so that the water content of the substrates is 35-40%, transplanting seedlings in the three-leaf period into flowerpots to continue being cultured for one month, and regularly spraying a naphthylacetic acid solution. Theorchardgrass is high in growth vigor, plants are high, the plants can reach up to 17.26 cm or above after being processed for 21 days, the tillering number is high and can reach 4 or above, the biomass increase is high in the growth process, and the method is simple, reliable and worthy of application and market promotion.

Description

technical field [0001] The invention mainly relates to the field of cultivation technology, in particular to a method for promoting the growth of Dactylis chinensis. Background technique [0002] Dactylis glomerata L. is native to Europe, North Africa and the temperate regions of Asia. Dactylis glomerata L. is now distributed in all temperate regions of the world. Dactylis alias, also known as orchard grass and chicken foot grass, belongs to the genus Dactylis in the Gramineae family. It has a high yield, good shade tolerance, and wide adaptability, and once grown, it can survive for many years. It can be used for green fodder, hay or silage and is one of the most important forages in the world. Because Dactylis is more resistant to barrenness and shade, it is especially suitable for returning farmland to forest and grass in the west of our country and establishing forest-grass composite vegetation. It is a more meaningful pasture in returning farmland to grass. [0003] ...
