Problems solved by technology

[0004] However, the current mature trough cultivation nutrient substrate is not completely suitable for bag cultivation.
Meng Jie et al. (2007), Li Shengli et al. (2006), Yan Huiling et al. (2010) conducted comparative studies on the nutrient substrate tank cultivation and bag cultivation of cucumber, muskmelon and gerbera respectively. The results showed that the same nutrient substrate It is not completely suitable for the two methods of trough cultivation and bag cultivation, that is, bag cultivation needs to develop a suitable cultivation matrix formula, and cannot completely copy the current trough cultivation nutrient matrix formula
At present, the matrix of bag cultivation mainly uses or partially adopts non-renewable raw materials such as peat, vermiculite, perlite, etc. Although its cultivation effect is good, its cost is high and it is not conducive to environmental protection. It has been difficult to popularize and apply it on a large scale.

Abstract

The invention mainly relates to a bag-culture composite nutritional matrix for tomatoes and preparation and nutrient and water management methods thereof. The matrix comprises the following components in percentage by volume: 30% of furfural residues, 20%-40% of cow dung and 30%-50% of crushed maize straws. The preparation method comprises the step of adding 1kg-1.5kg of a water retaining agent, 1.5kg-2kg of urea and 2kg-2.5kg of potassium sulphate to the fermented composite matrix per cubic meter. The matrix provided by the invention is wide in raw material source, low in cost, environment-friendly and suitable for standardized and large-scale production and management, saves resources, solves the problems of successive cropping obstacle of facility soil and poor utilization of soils which cannot be cultivated are effectively solved, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a compound nutrient substrate for tomato bag cultivation, its preparation and fertilizer and water management method. Background technique [0002] By 2012, the area of ​​solar greenhouse vegetables in my country has grown to 928,000 hectares, which not only successfully solved the problem of vegetable supply in winter and spring off-season in northern my country, but also became a pillar industry for solving the "three rural" issues in northern my country. However, the highly intensive and specialized production of vegetables in solar greenhouses has led to barriers to continuous cropping in facility soils, which has become an important factor restricting the development of my country's solar greenhouse vegetable industry. The problem of soil continuous cropping obstacles in facilities is a worldwide problem. Western developed countries represented by the Netherl...
