Embodiment 1

[0017] A method for growing seedlings of hybrid ramie seed plugs with shallow covering soil, comprising the steps of:

[0018] The selection of the seedbed of step A: select the terrain to be flat, and the plot with loose soil is used as the seedbed;

[0019] Step B Seedbed arrangement: before raising seedlings, ditch the inside of the tray according to the specifications of the tray as a chamber, the surface of the chamber on a gentle slope is parallel to the contour line, and the surface of the chamber is finely leveled;

[0020] Step C seed selection and sowing: select clean, full-grained hybrid ramie seeds, the amount of hybrid ramie seeds per acre of seedbed is 350-400g, and mix well according to the ratio that the quality of old plant ash is 25 times to 35 times the quality of hybrid ramie seeds. And sow the seeds evenly according to the method of compartmentalization, quantification, and repeated sowing, and then evenly spread the pretreated covering soil on the surface...

Embodiment 2

[0025] A method for growing seedlings of hybrid ramie seed plugs with shallow covering soil, comprising the following steps, the selection of a seedbed in step A: selecting flat terrain, leeward to the sun, convenient water source, easy irrigation, loose soil, loose soil is beneficial to the growth of seedlings, fertile land , less weeds, and the plots that have not been planted with ramie for more than two years are used as seedbeds.

[0026] Step B Seedbed arrangement: 2 to 3 days before seedling cultivation, according to the specifications of the tray, ditches can be made inside the tray according to the specifications of the box width of 100-110cm and the box groove of 30×20cm. The high lines are parallel, and the car surface is finely leveled, so that the top is solid and the bottom is empty, and the topsoil is fine and dense.

[0027] Step C seed selection and sowing: select hybrid ramie seeds that are clean, full in grain, and have an indoor germination rate of more tha...

Embodiment 3

[0034] Compared with the above-mentioned embodiment, the difference of this embodiment is that before the transplanting of the described seedlings, because in the process of growth, the leaves of the hemp seedlings cannot be controlled to be 8 to 12, and it is inevitable that the hemp seedlings with more leaves are produced. For those seedlings with a large number of leaves, part of the leaves should be subtracted from the seedlings with a plant height exceeding 40cm to reduce water transpiration, and avoid that during the transplanting process, due to the large number of leaves, the water evaporates faster, which will affect the quality of the seedlings during transplanting. Survival rate, when described seedlings are transplanted, when the seedlings grow to 10-12 true leaf stages, it is the best transplanting period. At this time, the hemp seedlings are in the strong seedling stage, and the transplanting survival rate is greatly improved.

Abstract

The invention discloses a seedling growing method for hybrid ramie seeds through plug shallow earthing. Land parcels which have a flat terrain and loose soil are selected as seedbed land, diseases andpests, grass seeds and the like in soil are killed by means of high temperature, ultraviolet lamp irradiation and other methods, the soil quality is improved, the influence of the diseases and pestsand the grass seeds on the seeds is lowered, the labor force is reduced, and the cost is lowered; besides, seedling growing is achieved by means of plug shallow earthing, transplanting is facilitated,plugs can be directly transported to a field in which ramie is about to be planted, and long-distance transportation is facilitated; by directly taking seedlings with soil out of the plugs, the rootsystems and growing points of the seedlings are protected, the water retention rate is high, and the survival rate of the young seedlings is increased.

Description

technical field [0001] The invention relates to the field of planting, and more specifically, the invention mainly relates to a method for cultivating seedlings of hybrid ramie seed plugs shallowly covered with soil. Background technique [0002] Ramie is a special product in my country, and its planting area and output account for more than 90% of the world. It is a perennial herbaceous natural fiber crop. The propagation methods of ramie are conventional vegetative propagation and seed propagation. At present, hybrid ramie seedlings are grown in field. However, there are many weeds, and manual weeding has a great impact on ramie seedling cultivation, and the labor cost is high. The method of artificially pulling seedlings is easy to damage the seedlings, which affects the survival rate of planting and is not conducive to long-distance transportation. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies, and t...
