Embodiment 1

[0031] Embodiment 1: The effect of the seedling-raising substrate of the present invention on the strong seedling index and G value of cucumber plug seedlings

[0032] The test was carried out in the solar greenhouse of the Horticultural Experimental Station of Shandong Agricultural University. According to the method described in the summary of the invention, chicken manure and cow manure were mixed and prepared in turn according to the volume ratio of chicken manure and cow manure: 0:1, 1:16, 1:8, and 1:4 to prepare chicken manure-cow manure For dung vermicomposting, 4 different vermicomposts are obtained after being inoculated with earthworms, and then vermicompost and vermiculite are prepared into four seedling substrates T1, T2, T3 and T4 at a volume ratio of 2:1, and peat and vermiculite are mixed by volume Mixed at a ratio of 2:1 as CK1, peat and vermiculite at a volume ratio of 2:1 and simultaneously watered with Yamazaki’s formula nutrient solution for cucumbers as CK2...

Embodiment 2

[0040] Embodiment 2: Effect of the present invention's seedling-raising substrate on the photosynthetic rate and root vigor of cucumber plug seedlings

[0041] The test was carried out in the solar greenhouse of the Horticultural Experimental Station of Shandong Agricultural University, and the substrates and treatment methods for each treatment were the same as those in Example 1. On May 31, each treatment randomly selected seedlings and used the CIRAS-2 photosynthetic instrument provided by Lufthansa Scientific Instruments to measure the growth of seedlings. Photosynthetic rate and root activity were measured by triphenyltetrazolium chloride (TTC), and each treatment was repeated 3 times.

[0042] Plants convert inorganic matter into organic matter through photosynthesis to directly or indirectly provide food for humans and animals, and the photosynthetic rate reflects the strength of photosynthesis. The root system is the main organ for plants to absorb water and mineral nu...

Embodiment 3

[0043] Embodiment 3: Effect of the seedling-raising substrate of the present invention on the output of cucumber plug seedlings after field planting

[0044] The experiment was carried out in the solar greenhouse of the Horticultural Experiment Station of Shandong Agricultural University. Cucumber seeds were soaked and sterilized, and placed in an incubator (28°C) to germinate. On August 17th, the seedlings that germinated were selected to be sown in a 50-hole plug tray, and the substrates and treatment methods for each treatment were the same as in Example 1. On September 2, 15 seedlings with consistent growth were selected from each treatment and planted in the greenhouse Inside, the row spacing is 55cm, and the plant spacing is 35cm. Appropriate watering after planting and before sitting melons, without top dressing; root melons combined with watering for top dressing after harvesting, watering once every 2 days during the full melon period to keep the soil moist; top dres...

Abstract

The invention provides a cucumber plug seedling substrate free of watering a nutrient solution and a preparation method thereof, belonging to the technical field of agricultural seedling cultivation. The preparation method comprises the steps of: mixing chicken manure and cow dung according to a volume ratio of 1: 4-16, and then inoculating earthworm for composting; after foodstuff is completely digested, obtaining loose and porous granulate earthworm cast with abundant nutrient elements and good air permeability, nutrient preserving capability as well as water-retaining property; and then mixing the earthworm cast with vermiculite according to a volume ratio of 2: 1 uniformly so as to obtain the cucumber plug seedling substrate free of watering a nutrient solution. The seedling substrate overcomes the disadvantages of low content of nutrient elements, unbalanced content of nitrogen phosphorus and potassium and insufficient supply of the common earthworm cast in the market. The experiment proves that the root activity, the strong seedling index, the dry and fresh weight of the plant and the output after the field planting of the plant cucumber seedling raised by the seedling substrate are obviously better than the traditional turf and vermiculite compound substrate which is watered with the nutrient solution. While replacing the turf, the seedling substrate realizes resource utilization of the excrement of animals and reduces environment pollution. Therefore, the cucumber plug seedling substrate free of watering nutrient solution has obvious economic benefits, social benefits and ecologic benefits.

Description

technical field [0001] The invention relates to a cucumber plug seedling-growing substrate free of pouring nutrient solution and a preparation method thereof, belonging to the technical field of agricultural production. technical background [0002] With the development of my country's vegetable industry and the advancement of industrialized agriculture, industrialized seedlings have gradually replaced traditional seedlings. At present, peat and peat are mostly used as seedling substrates in the industrial seedling raising process. These seedling substrates are mostly non-renewable resources. After years of mining, their reserves have been decreasing, and the development process has caused huge damage to the environment; peat is mainly produced in Northeast China and Southwest China has certain geographical restrictions, which increase the cost of seedling substrates such as peat and peat. Therefore, people began to look for new materials to replace seedling substrates such ...
