Problems solved by technology

[0004] The vegetable residues are composted, and the compost products replace peat for the preparation of seedling substrates, which can not only realize the resource utilization of vegetable residues, reduce the environmental pollution caused by waste or incineration, but also alleviate the impact of over-exploitation of peat. The destructive effect caused by the ecological environment, therefore, has obvious economic benefits, social benefits and ecological benefits, and there is no report in this regard at present

experiment example 1

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

[0030] Zhongza 105 was selected as the test material, and the seeds were provided by the Tomato 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. Tomato 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 16, seeds that had germinated uniformly were selected and sowed...

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

[0037] Zhongza 105 was used as the test material, and the seeds were provided by the Tomato Breeding Research Group of the Institute of Vegetable and Flower Research, 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. Tomato seeds were soaked and sterilized, and placed in a constant temperature incubator (28°C) for germination. On June 8, seeds that germinated uniformly were selected and planted into 72-hole plug trays, and the seedling raising substrates and fertilization methods of each treatment were the same as in Experimental Example 1.

[0039] On July 10, the second fully expanded leaf from the growing point was selected, and the chlorophyll content of the seedling leaves w...

[0041]Experimental example 3. the effect of substrate of the present invention on the output of tomato seedlings after colonization

[0042] Zhongza 105 was selected as the test material, and the seeds were provided by the Tomato 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-hydrolyzed 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. Tomato seeds were soaked and sterilized, and placed in a constant temperature incubator (28°C) for germination. On August 5th, seeds that germinated uniformly were selected to be sown into 72-hole plug trays, and the seedling raising substrate and fertilization method of eac...

Abstract

The invention relates to a tomato seedling substrate and a preparation method thereof, which belong to the technical field of agricultural seedling. The raw material components of the tomato seedling substrate comprise a vegetable stump compost product, grass carbon and vermiculite in the volume ratio of 4 to 6:2 to 3: 2 to 3, wherein vegetable stumps refer to hot pepper stumps, cucumber stumps and cabbage stumps, and the stumps refer to plants or plant tissues abandoned in fields after the picking of human beings is finished. The invention is most suitable for tomato seedling, and a cultivated tomato seedling is superior to a traditional conventional seedling substrate in the aspects of root system vitality, leaf chlorophyll content, seedling indexes and prophase yield after field planting. The seedling substrate of the invention reduces the usage amount of the grass carbon, is beneficial to saving grass carbon resources and achieves the purposes of resource utilization of the vegetable stumps and reduction of environmental pollution. Therefore, the invention has remarkable economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a tomato seedling-raising substrate and a preparation method thereof. Background technique [0002] Tomato 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 ​​tomato in my country in 2006 was 834,700 hm 2 ("Chinese Vegetables", No. 1, 2008). Tomato production is mainly based on seedling cultivation and transplanting. At present, peat and vermiculite composite matrix (2:1, v / v) is usually used for tomato seedling cultivation ("Vegetables", No. 4, 2007). However, peat is a non-renewable resource, and excessive exploitation will inevitably damage the ecological environment, especially It is a wetland environment ("Journal of Yunnan Agricultural University", No. 2, 2007), and the country has formulated relevant regulations to limit or prohibit the developmen...
