Embodiment 1

[0039] Embodiment 1: A kind of common wild rice stem potted preservation method

[0040] 1.1 Selection and treatment of seed stems

[0041] From the common wild rice field preservation nursery established, 87 materials with certain representative morphological characteristics and distribution areas were selected, and the stems with green bases and white roots and axillary buds were intercepted, dead stems and leaves were trimmed, and Hang signage to avoid confusion ( figure 1 ).

[0042] 1.2 Preparation of cultivation medium

[0043] Imported moss peat, wood fiber, coconut peat, and coconut blocks are selected as the main raw materials, and the volume ratio is 35%: 20%: 25%: 20% ( figure 2 ). Among them, the peat soil has a particle size of 5-20 mm, which has strong buffering and water-retaining and fertilizer-retaining capabilities; wood fiber has the characteristics of high porosity, natural moisture absorption, and fast conduction, and is widely used in potted flowers, C...

Embodiment 2

[0053] The same as the method of Example 1, the only difference is that moss peat, wood fiber, coir peat, and coconut block are used as raw materials, and the ratio is 32%: 18%: 23%: 19%.

Embodiment 3

[0055] The method is the same as that of Example 1, except that moss peat, wood fiber, coir peat, and coconut block are used as raw materials, and the ratio is 35%: 18%: 26%: 20%.

Abstract

The invention provides a potting preservation method for common wild rice seed stems, and relates to the technical field of rice planting. The preservation method comprises the following steps: cutting green stems with white new roots and axillary buds on bases of wild rice seedlings as seed stems; and cultivating and planting the seed stems in pots filled with nutrient soil, and then carrying out daily maintenance and preservation, wherein the nutrient soil comprises the following components in parts by volume: 30-40 parts of moss peat, 15-25 parts of wood fiber, 20-30 parts of coco coir and 10-30 parts of coconut blocks. The preservation method effectively solves the problems of high management difficulty, mechanical mixing, soil hardening, weak plant growth vigor and the like of common wild rice.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for preserving common wild rice seed stems in pots. Background technique [0002] Common wild rice (Oryza rufipogon Griff.) is a grass plant, which is the ancestor of Asian cultivated rice (Oryza sativa L.), and common wild rice is distributed in 8 provinces (regions) in southern China. Common wild rice contains many excellent genes such as disease resistance, insect resistance, stress resistance, high yield and high quality in long-term natural selection, and is an important germplasm resource for rice variety improvement. [0003] In recent years, the original habitat of the natural distribution of common wild rice has been damaged to varying degrees, and many common wild rice are on the verge of extinction. If the collected wild rice samples are not well preserved, once lost, they will never be recovered; in addition, The genome of this species is the same type...
