experiment example 1

[0029] Experimental example 1. the effect of seedling-raising substrate of the present invention on pepper seedling strong seedling index

[0030] Zhongjiao No. 6 was selected as the test material, and the seeds were provided by the pepper breeding research group of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences.

[0031] Huaduoduo No. 1 (N-P 2 o 5 -K 2 O=20-20-20), Huaduoduo 8 (N-P 2 o 5 -K 2 O=20-10-20) Water-soluble quick-acting fertilizer was purchased from Beijing Dahan Agricultural Technology Co., Ltd.

[0032] The experiment was carried out in the solar greenhouse of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. Pepper seeds were sterilized by 5% NaClO for 15 minutes, soaked for 4 hours, placed in a Φ15 petri dish covered with double filter paper, and germinated in a constant temperature incubator (28°C). On March 8, seeds that had germinated uniformly were selected and so...

[0036] Experimental example 2. the effect of substrate of the present invention on chlorophyll content and root system vigor of capsicum seedling

[0037] Zhongjiao No. 6 was used as the test material, and the seeds were provided by the pepper breeding research group of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences.

[0038] The experiment was carried out in the solar greenhouse of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. After the pepper seeds are soaked and sterilized, they are placed in a constant temperature incubator (28°C) for germination. On May 6, seeds that germinated uniformly were selected and planted into 72-hole plug trays, and the seedling raising substrate and fertilization method of each treatment were the same as in Experimental Example 1.

[0039] On June 20, the second fully expanded leaf from the growing point was selected, and the chlorophyll content of the s...

experiment example 3

[0041]Experimental example 3. the effect of seedling-raising substrate of the present invention on the output of capsicum seedlings after planting

[0042] Zhongjiao No. 6 was selected as the test material, and the seeds were provided by the pepper breeding research group of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences.

[0043] The organic matter content of the solar greenhouse soil is 3.12%, and the alkali-hydrolyzable nitrogen is 146.3mg·kg -1 , available phosphorus 576.5mg·kg -1 , available potassium 296.2mg·kg -1 .

[0044] The experiment was carried out in the solar greenhouse of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. After the pepper seeds are soaked and sterilized, they are placed in a constant temperature incubator (28°C) for germination. On July 26, seeds that germinated uniformly were selected and planted in 72-hole plug trays. The seedling substrates and fertili...

Abstract

The invention relates to a pepper seedling raising medium and a preparation method thereof, belonging to the technical field of agricultural seedling raising. The pepper seedling raising medium comprises the following raw material components: a vegetable stubble compost product, grass peat and vermiculite, wherein the volume ratio of the components is 3-5:2-3:2, and the vegetable stubble compost product comprises pepper stubbles, cucumber stubbles and common head cabbage stubbles; and the stubble means a plant or a plant tissue which is left in the field after finishing the picking. The medium is most suitable for pepper seedling raising, and is more excellent than the existing conventional seedling raising medium in the root activity, chlorophyll content, sound seedling index and early yield after planting of the raised pepper seedlings. The seedling raising medium of the invention reduces the use amount of grass peat, is favorable for saving grass peat resources and achieves the purposes of the resource utilization of vegetable stubbles and the reduction of environmental pollution. Therefore, the invention has obvious economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a pepper seedling raising substrate and a preparation method thereof. Background technique [0002] Pepper is one of the vegetables with a large planting area in my country. According to the statistics of the Ministry of Agriculture, the sowing area of ​​pepper in my country in 2007 was 1.3 million ha 2 ("Jilin Vegetables", No. 4, 2008). Pepper production is mostly based on seedling cultivation and transplanting. At present, peat and vermiculite composite matrix (2:1, v / v) is usually used for pepper seedling cultivation ("Northern Horticulture", No. 1, 2006), but peat is a non-renewable resource, and excessive exploitation will inevitably destroy the ecological environment. Especially in the wetland environment ("Journal of Yunnan Agricultural University", No. 2, 2007), the country has formulated relevant regulations to limit or prohibit the developm...
