Problems solved by technology

In addition, some organic nutrient solutions need to add ingredients such as traditional Chinese medicine or traditional Chinese medicine dregs. In addition to difficulty in obtaining it, there is also a problem of high cost.
[0005] Organic ecological soilless cultivation is the research result of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. This technology successfully introduces organic agriculture into modern soilless cultivation, which greatly simplifies the operation procedures of soilless cultivation water and fertilizer management, but the topdressing method of solid fertilizer needs to be increased. Manual, and labor-intensive
[0006] Currently, the nutrient solution and / or nutrient matrix suitable for tomato soilless cultivation cannot achieve the effects of simple ingredients, low cost, and convenient use.

Embodiment 1

[0040] Table 1 The formula of simple nutrient solution for spring stubble tomatoes is as follows: (unit: mmol / L)

[0041]

[0042] In the supporting cultivation medium, every 1m 3 Add 55kg of fully fermented and air-dried cow dung to coconut bran.

[0043] Table 2 The formula of simple nutrient solution for autumn stubble tomato is as follows: (unit: mmol / L)

[0044]

[0045] In the supporting cultivation medium, every 1m 3 Add 45kg of fully fermented and air-dried cow dung to coconut bran.

Embodiment 2

[0046] Application of Example 2 Simple Nutrient Solution Formula in Soilless Cultivation Tomato

[0047] In 2016, in the Jinliuhuan Agricultural Park in Changping District, Beijing, coconut bran was used as the cultivation substrate, and the effects of the following three nutrient supply methods on tomatoes were compared by using the slot culture planting method. The cultivation slot width was 0.48 meters, and the substrate thickness was 0.13 meters, 7 meters long. For each treatment of 6 cultivation tanks, 1 cultivation tank is 1 repetition, 4 repetitions, and 1 tank on each side is set as a protection area.

[0048] The tomato variety is Debelle, a medium-to-large fruit variety with a single fruit weight of about 200 grams. The planting time for spring stubble is from February to July, with 7 to 8 ears of fruit remaining; the planting time for autumn stubble is August to January of the next year. The number of remaining fruit is 6-7 ears.

Abstract

The invention discloses a soilless culture nutrient suitable for tomatoes and a culture method for tomatoes in a coconut bran culture medium. The nutrient comprises a culture medium and a simple nutrient solution, wherein the culture medium is composed of coconut bran and dried and fully-fermented cow dung; the nutrient solution solvent is composed of water and inorganic salt ions, wherein the inorganic salt ions are composed of NO3-, NH4+, K+, Ca2+, Mg2+ and B3+. The culture method is also based on the above nutrient and comprises the following steps: adding the dried and fully-fermented cow dung to the coconut bran before tomato seedlings are transplanted and planted, and irrigating the simple nutrient solution after the tomato seedlings are planted. Based on the coconut bran culture medium containing the cow dung, cooperating with the inorganic nutrient solution and according to tomato growth characteristics and nutritional requirements at different stages, the soilless culture nutrient suitable for tomatoes and the culture method for tomatoes in the coconut bran culture medium has the advantages that organic fertilizer and soilless cultivation technology are closely integrated; the quality and yield of tomatoes are improved; the using of chemical fertilizer is reduced; the sustainable development is achieved, and the use efficiency of the fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a soilless cultivation material suitable for tomato and a method for cultivating tomato with coconut bran substrate. Background technique [0002] Tomato is one of the important solanaceous vegetables, and it has been occupying a very large proportion in the cultivation of protected areas in my country in recent years. [0003] Most of the existing tomato-specific nutrient solution formulas are all-inorganic formulas, and the nutrient solution preparation is complicated, and it is necessary to consider three macroelements (nitrogen, phosphorus, potassium) and two medium elements (calcium, magnesium) required for crop growth. And 6 kinds of trace elements (iron, zinc, copper, manganese, boron, molybdenum), the cost is high, and all of them are inorganic nutrients, which is not conducive to sustainable development. [0004] The patent document with publication number ...
