preparation example Construction

[0026] The present invention also provides a preparation method of the flower nursery stock cultivation nutrient soil described in the above technical solution, comprising the following steps:

[0027] After mixing the raw materials evenly, carry out stacking aerobic fermentation, and continue to ferment at a high temperature above 55°C for more than 7 days. During the post-decomposition fermentation stage, turn the pile once every 3 days until the temperature of the pile body is close to the indoor air temperature, and the decomposed material is obtained.

[0028] In the present invention, adding a slow-release fertilizer is also included after the decomposed material is obtained.

Embodiment 1

[0031] The present invention selects dredging bottom mud suitable for garden flowers, cashew nut shells, and vegetable stalks for aerobic fermentation, and then performs cultivation tests on five different seedlings.

[0032] Materials and Methods

[0033] In view of the high pH of the dewatered dredging sediment (>8.5, in order to accelerate the precipitation of solid particles in the mud during large-scale dredging operations, a large amount of alkaline substances are often put into the mud, resulting in a strong alkaline pH of the dewatered sediment) And the problems of soil compaction, low organic matter, and lack of nutrients. Taking the bottom mud and forest land soil cultivation as a comparison, the dehydrated bottom mud, cashew nut shells, vegetable straws and other materials were used to prepare nutrient soil for flower seedling cultivation, and a total of 5 varieties of flower seedlings were planted. , are respectively: Photinia fragrans, bamboo cypress, green treasu...

Abstract

The invention relates to flower and plant nursery stock cultivation nutrition soil and a preparation method thereof, and belongs to the technical field of plant cultivation. Preparation raw materialsof the flower and plant nursery stock cultivation nutrition soil comprise, in volume percent, 30-50% of bottom mud, 0-40% of cashew nut shells and 10-40% of vegetables straws. Harmlessly treated dredging bottom mud and agricultural and forest wastes are developed into economical and applicable nursery stock cultivation medium nutrition soil, the problem of environmental pollution caused by unsuitable treatment of the wastes can be solved, waste materials can be recycled, application amount of non-renewable resources such as oil and grass carbon and fertilizers in current flower and plant nursery stock cultivation is reduced, the production cost of the flower and plant nursery stock cultivation medium nutrition soil is reduced, and the nutrition soil has obvious economic, social and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a nutrient soil for flower nursery stock cultivation and a preparation method thereof. Background technique [0002] The flower seedling industry has become one of the important industries in Zhejiang Province in recent years. Many flower seedlings in Zhejiang Province are exported after planting, and most of them are transplanted with soil. As a result, a large amount of cultivated land soil is destroyed, and it is difficult to re-cultivate in the future. Therefore, in recent years, More and more horticultural companies have begun to try to use horticultural substrates instead of soil to cultivate flower seedlings, but the substrate materials used are mainly peat and coconut peat. On the one hand, peat is a non-renewable resource. With the massive exploitation of peat resources It will also cause damage to the local environment. Therefore, in recent years, many peat-pr...
