experiment example 1

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

[0030] Jingxin No. 1 was selected as the test material, and the seeds were purchased from the seed sales department 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. Watermelon seeds were sterilized by 5% NaClO for 10 minutes, soaked for 6 hours, placed in a Φ15 petri dish covered with double filter paper, and germinated in a constant temperature incubator (28°C). On March 25, seeds that germinated uniformly were select...

experiment example 2

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

[0037] Jingxin No. 1 was used as the test material, and the seeds were purchased from the seed sales department 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. Watermelon seeds were soaked and sterilized, and placed in a constant temperature incubator (28°C) for germination. On May 6, seeds that germinated uniformly were selected and planted into 50-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 2, the second fully expanded leaf from the growing point was selected, and the chlorophyll content of the seedling leaves...

experiment example 3

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

[0042] Jingxin No. 1 was selected as the test material, and the seeds were purchased from the seed sales department 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. Watermelon seeds were soaked and sterilized, and placed in a constant temperature incubator (28°C) for germination. On July 22, seeds that germinated uniformly were selected and planted in 50-hole plug trays. The seedling raising substrates and fertil...

Abstract

The invention relates to a watermelon seedling culturing substrate and a preparation method, and belongs to the technical field of agricultural seedling culturing. The watermelon seedling culturing substrate comprises the following raw materials of vegetable stubble compost products, grass carbon and vermiculite in a volume ratio of 3-5:1:2, wherein vegetable stubble comprises pepper stubble, cucumber stubble and common head cabbage stubble; and stubble is a plant to a plant tissue left in a field by human after finishing picking. The substrate is most suitable for watermelon seedling culturing; the root activity, the leaf chlorophyll content, strong seedling indicators and the early yield after field planting of cultured watermelon seedlings are superior to those of the watermelon seedlings cultured by using the conventional seedling culturing substrate. The seedling culturing substrate of the invention reduces the using amount of the grass carbon, contributes to saving grass carbon resources, fulfills the aims of resource utilization of the vegetable stubble and reduction of environmental pollution, and has obvious economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of agricultural seedling raising, and in particular relates to a watermelon seedling raising substrate and a preparation method thereof. Background technique [0002] Watermelon is one of the vegetables with a large planting area in my country. According to the statistics of the Ministry of Agriculture, the planting area of ​​watermelon in my country in 2006 was 1.7851 million ha 2 ("Chinese Vegetables", No. 2, 2008). Watermelon production is mostly based on seedling cultivation and transplanting. At present, peat and vermiculite composite substrates (2:1, v / v) are usually used for watermelon seedling cultivation ("Chinese Melon Vegetables", No. 1, 2006), but peat is a non-renewable resource, and excessive exploitation will inevitably destroy the ecological environment. , especially the wetland environment ("Journal of Yunnan Agricultural University", No. 2, 2007), the country has formulated relevant regul...
