Embodiment 1

[0039] Table 1 The formula of the simple nutrient solution of spring stubble cucumber is as follows: (unit: mmol / L)

[0040]

[0041] In the supporting cultivation medium, every 1m 3 Add 60kg of cow dung to coconut bran and add 1.5kg of diammonium phosphate.

[0042] Table 2 The formula of simple nutrient solution for cucumbers in autumn stubble is as follows: (unit: mmol / L)

[0043]

[0044] In the supporting cultivation medium, every 1m 3 Add 50kg of cow dung to coconut bran and add 1.0kg of diammonium phosphate.

Embodiment 2

[0045] Application of Example 2 Simple Nutrient Solution Formula in Soilless Cucumber

[0046] In 2016, at the Nankou Farm of the Academy of Agricultural Sciences in Changping District, Beijing, coconut bran was used as the cultivation substrate, and the effects of the following three nutrient supply methods (three culture solutions) on cucumbers were compared using the slot culture method. The width of the cultivation tank is 0.48 meters, the thickness of the substrate is 0.13 meters, and the length is 8 meters. For each treatment of 8 cultivation tanks, 2 cultivation tanks are 1 repetition, 3 repetitions, and 1 tank on each side is set as a protection area.

[0047] The cucumber variety is Zhongnong 26, and the spring stubble is planted from February to July; the autumn stubble is planted from September to January of the following year.

[0048] The simple formula is as in Example 1. Before planting coconut bran substrate in spring, apply 60 kg / m3 of fermented cow dung and ...

Abstract

The invention discloses a soilless culture nutrient applicable to cucumbers and a culture method of coconut chaff substrate cultured cucumbers. The nutrient comprises a culture substrate and a simple nutrient solution, wherein the culture substrate is prepared from coconut chaff, dried cow dung which is completely fermented and diammonium phosphate; the simple nutrient solution takes water as a solvent; inorganic salt ions are composed of NO3<->, NH4<+>, K<+>, Ca<2+>, Mg<2+> and B<3+>. The culture method comprises the following steps: based on the nutrient, before transplanting cucumber seedlings and carrying out fixed planting, applying the dried cow dung which is completely fermented and the diammonium phosphate into coconut chaff; after fixed planting, irrigating the simple nutrient solution. According to the soilless culture nutrient applicable to the cucumbers and the culture method of the coconut chaff substrate cultured cucumbers, a coconut chaff substrate containing the cow dung is matched with an inorganic nutrient solution; organic fertilizer is tightly combined with a soilless culture technology according to growth characteristics of the cucumbers and nutrient requirements of different phases, so that the quality and yield of the cucumbers are improved and the dosage of chemical fertilizer is reduced; sustainable development is realized and the utilization 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 cucumbers and a method for cultivating cucumbers on a coconut bran substrate. Background technique [0002] Cucumber is one of the important melon vegetables, and it has always occupied a large proportion in the cultivation of protected areas in my country in recent years. [0003] The existing nutrient solution for cucumber is mainly an all-inorganic formula, and the preparation of the nutrient solution is complicated, and it is necessary to consider three kinds of macroelements (nitrogen, phosphorus, potassium), two kinds of medium elements (calcium, magnesium) and six kinds of elements required for crop growth. Trace elements (iron, zinc, copper, manganese, boron, molybdenum) are costly and all of them are inorganic nutrients, which is not conducive to sustainable development. [0004] Organic ecological soilless culti...
