Problems solved by technology

At present, peat is considered to be the most ideal substrate, but due to the restricted development and utilization of natural peat, some countries even ban mining, and it is necessary to develop a substitute for peat as soon as possible
The development and utilization of rock wool in foreign countries is relatively ideal. In recent years, it has been found that there are carcinogens in the matrix rock wool commonly used in soilless cultivation in the world, which has brought obstacles to its application.

Embodiment Construction

[0010] Below in conjunction with specific embodiment, further illustrate the present invention. It should be noted that the examples are only for illustrating the present invention and do not limit the scope of the present invention.

[0011] The composite substrate for soilless cultivation of tomato in sandy land is prepared by the following method:

[0012] (1) Screening and disinfection of sand.

[0013] The sand was taken from the local wasteland and passed through a 50-mesh sieve. Rinse the sifted sand with water and expose it to the sun.

[0014] (2) Screening and disinfection of sawdust.

[0015] Sawdust is screened and graded, preferably with a length of 3-7mm, rinsed with water and then exposed to the sun.

[0016] (3) Water control treatment of decomposed cow manure and expanded chicken manure.

[0017] The decomposed cow dung is exposed to the sun until dry, fully soaked and evenly mixed according to the mass ratio of dry cow dung to water of 2:3.

[0018] The...

Abstract

The invention discloses a formula and a preparation method of a tomato sand soilless cultivation composite medium, which belong to the technical field of agricultural plant soilless cultivation. The composite medium is prepared by uniformly mixing sand, saw dust, cow dung and chicken manure in a volume ratio of 5:3:1:1. The main raw materials of the soilless cultivation composite medium provided by the invention are the most common sand from sandy areas and waste wood flour, cow dung and chicken manufacture from industrial and agricultural production instead of medium peat which is used universally in current cultivation, so the production cost is reduced, resources are saved, environmental pollution is reduced, and ecological sound circulation is realized. Meanwhile, the formula medium disclosed in the invention is scientific in mixing ratio and complete in nutrients, helps to realize high yield easily and ensures that the products are safe and free from public hazard, and thus, the formula medium has certain promoting effect on the agriculture and economic development in sandy areas.

Description

1 technical field [0001] The invention belongs to the technical field of soilless cultivation of agricultural science plants, and in particular relates to a compound substrate formula for soilless cultivation of tomato in sandy land and a preparation method thereof. 2 background technology [0002] China is one of the countries with many deserts. The total area of ​​deserts is about 1.3 million square kilometers, accounting for about 13% of the country's land area. In order to improve the land utilization rate, rationally develop and utilize the desert and make full use of the desert's light resources, the development of sand facility agriculture is one of the effective and feasible ways. Facility vegetables have a large area in our country, but they are basically facility soil cultivation, but facility soil cultivation has fatal shortcomings such as obstacles to continuous cropping and secondary salinization of soil. In recent years, due to physiological barriers, continuo...
