Coco coir paper sludge substrate suitable for tomato plantation and preparation method thereof

Abstract

The invention discloses a coco coir paper sludge substrate suitable for tomato plantation and belongs to the technical field of tomato plantation. The substrate is composed of raw materials and additives. The raw materials comprise, by volume percent, 28-38% of paper sludge, 28-36% of vermiculite, 7-8% of river sand and 26-40% of coco coir. In 1 m3 of raw materials, the added additives comprise 1.5 kg of microbial fermentation bacteria agent, 0.8 kg of organic fertilizer and 15 g of 500-fold chlorothalonil wettable powder with a concentration of 75%. The method for preparing the substrate comprises the steps of pre-composting the paper sludge with a humidity of 50-60% and the coco coir in proportion and then adding the additives in proportion, covering the raw materials with a shed film, overturning a pile once every week, continuing for 5-7 weeks, and fully and evenly mixing the compost with the vermiculite and the river sand in proportion. The substrate is favorable for enabling tomatoes to grow consistently, making plants robust, making leaf colors bright, making the seedling stage disease less, making overall characters excellent and making the rate of finished products high; since the paper sludge is extensive in resource source and low in cost, pollution in the paper sludge treatment process can be avoided, and the coco coir paper sludge substrate further has the advantage of environmental protection.

Description

technical field [0001] The invention relates to the technical field of tomato planting, in particular to a coconut bran paper mud substrate suitable for tomato planting and a configuration method thereof. Background technique [0002] Tomato, also known as tomato, is one of the most commonly cultivated fruits and vegetables in the world. In the process of tomato planting, seedlings are usually transplanted. Studies have shown that different seedling substrates significantly affect the growth and development of tomato seedlings. In the process of seedlings , mainly using a mixture of organic fertilizer and mellow soil as the substrate, which often leads to the following problems at the seedling stage: first, it is prone to seedling diseases, especially damping-off; weak. How to screen suitable raw materials to prepare seedling substrates has become a problem to be solved urgently. [0003] Paper slime is the terminal product of wastewater treatment in the papermaking proces...
