Description

本発明は、水耕栽培装置及びその運転方法に関する。  The present invention relates to a hydroponic cultivation apparatus and an operation method thereof.
微生物の働きを植物栽培に利用する技術は、土耕栽培では、有機栽培として確立されている。しかし、水耕栽培では、微生物のエサとなる根の分泌有機物が水耕養液に溶解して根圏域外へ流出するため、土耕栽培に比べその濃度が低く微生物の繁殖が少ない(非特許文献1参照。)。また、水耕養液中のフザリウム、ピシウム等の病原性糸状菌が甚大な被害を発生させるため、生産者の病害への警戒から、水耕生産現場での微生物の利用が限定されているのが現状である。  The technique of utilizing the action of microorganisms for plant cultivation is established as organic cultivation in soil cultivation. However, in hydroponics, the secretory organic matter of the roots that feed the microorganisms dissolves in the hydroponic solution and flows out of the rhizosphere, so the concentration is low and the growth of microorganisms is low compared to soil cultivation (non-patented) Reference 1). In addition, pathogenic filamentous fungi such as fusarium and psium in hydroponic liquids cause enormous damage, so the use of microorganisms at hydroponic production sites is limited due to warnings of producers' diseases. Is the current situation.
従来の水耕栽培における微生物利用においては、微生物を付加した有機物のみを含んだ液を水耕養液として使用する方法がとられている。例えば、有機性廃棄物で有益微生物を培養した液や、微生物を含んだ腐食質を抽出した液、有益菌を付加した発酵汚泥や堆肥を含んだ液を水耕養液として使用するなどである(例えば、特許文献1〜3参照。)。これらの技術においては、養液循環型水耕装置を有し、有機物を含んだ液の作成または循環のための独自の装置をそなえている。  In the use of microorganisms in conventional hydroponics, a method of using a liquid containing only organic matter added with microorganisms as a hydroponic liquid is used. For example, liquids containing beneficial microorganisms cultivated with organic waste, liquids extracted from corrosive substances containing microorganisms, liquids containing fermented sludge and compost added with beneficial bacteria are used as hydroponics. (For example, refer patent documents 1-3.). In these techniques, there is a nutrient solution circulation type hydroponic device and a unique device for producing or circulating a liquid containing organic matter.

上記した実施形態における各部の構成は一例であり、本発明の技術思想の範囲で種々の変形が可能である。以下、本発明プラントの運転方法に関する実施例を示す。  The configuration of each part in the above-described embodiment is an example, and various modifications can be made within the scope of the technical idea of the present invention. Hereinafter, the Example regarding the operating method of this invention plant is shown.
精製ブドウ糖の投与基準量は、1回あたり150〜450グラムとする。通常は、毎朝1回、ブドウ糖300グラムを温水8リットルに溶かして養液タンクに投与する。生育を促進させる場合は、1回あたりの量を増やすとともに、1日当たり3回までの範囲で投与回数を増やす。  The administration standard amount of purified glucose is 150 to 450 grams per time. Normally, once every morning, 300 grams of glucose is dissolved in 8 liters of warm water and administered to the nutrient solution tank. When promoting growth, the amount per administration is increased and the number of administrations is increased up to 3 times per day.
栽培開始当初及び栽培植物の生育低下傾向が認められた時のみ、2〜3日おきに効果が現れるまで、1回あたり、培養した光合成細菌20リットルを養液タンクに投与するとともに、植物、床面上壌(2)に180リットル程度を動力噴霧機にて散布する。
光合成細菌の培養方法は、水耕養液200リットルを薬液タンクに入れ、紅色非硫黄細菌50ミリリットル、ブドウ糖150グラムを加え、撹拌し、小型観賞魚用バブリング装置をセットして、温室内の日光のあたる場所に24時間〜48時間放置する。
Only at the beginning of cultivation and when a tendency to reduce the growth of cultivated plants is observed, until the effect appears every 2-3 days, 20 liters of cultured photosynthetic bacteria are administered to the nutrient solution tank once, Sprinkle about 180 liters on the surface (2) with a power sprayer.
The culture method for photosynthetic bacteria is as follows: Put 200 liters of hydroponic culture solution in a chemical tank, add 50 ml of red non-sulfur bacteria and 150 grams of glucose, stir, set a bubbling device for small ornamental fish, and put sunlight in the greenhouse. Leave it for 24 to 48 hours.
本発明プラントにて、熱帯アジア(中国南部)原産の最低生育温度18度を必要とする空心菜を栽培した例を示す。
空心菜は越年し、成株となったものを使用し、面積1000平方メートル、有効栽培ベッド面積600平方メートル、養液タンク5トンのNFT式水耕装置(養液完全循環型)を使用し、本発明の方法で4月〜11月までの8ヶ月間栽培し、1年間普通栽培した比較例と空心菜の月間生産量の変化を比較した。
図2は、その結果をグラフにしたものである。比較例では、春〜夏季にかけて収量が増加し、秋〜冬季にかけて収量が減少する通常の水耕栽培の生育パターンを示しているのに対し、本発明では、春〜秋季の全栽培期間中収量が変わらないという結果となった。空心菜は、気温の低下に弱く、特に11月以降は、例年収量が大幅に落ち込むのが普通だが、本発明では収量の低下が見られなかった。それとは逆に、空心菜の生育適期の夏季高温時においても、本発明では収量の増加が見られなかった。これは、比較例が気温・日照等の気象条件の影響を受けて、光合成量に比例した肥料吸収をし、光合成生産物をもとに生長するのに対し、本発明では、微生物活動の影響を受けて、微生物の運動量に比例した肥料吸収をし、光合成生産物と微生物の代謝栄養物の両方をもとに生育することが原因と思われる。このように、本発明で生産した場合、植物の生育・収量が周年変化しない傾向があり、秋〜冬季の低温時に肥料消費量が大幅に増加する(普通栽培の1.5〜2倍)。
An example of cultivating air-conditioned vegetables that require a minimum growth temperature of 18 degrees native to tropical Asia (southern China) in the present invention plant is shown.
Sorashinna is a year-round, grown plant that uses an NFT-type hydroponic device (a nutrient solution complete circulation type) with an area of 1000 square meters, an effective cultivation bed area of 600 square meters, and a nutrient solution tank of 5 tons. The change of the monthly production amount of the comparative example which was cultivated for eight months from April to November by the method of the invention, and was normally cultivated for one year, and empty heart vegetables was compared.
FIG. 2 is a graph of the results. The comparative example shows a normal hydroponics growth pattern in which the yield increases from spring to summer and decreases from autumn to winter, whereas in the present invention, the yield during the entire cultivation period from spring to autumn is shown. As a result, no change. Sorashinsai is vulnerable to a decrease in temperature, and after November, it is normal for the yield to drop drastically every year. However, in the present invention, no decrease in yield was observed. On the other hand, no increase in yield was observed in the present invention even at high summer temperatures, which is the optimal growth period for Sorashinsai. This is because the comparative example is influenced by weather conditions such as temperature and sunshine, absorbs fertilizer proportional to the amount of photosynthesis, and grows based on the photosynthetic product. In response to this, it is considered that the fertilizer is absorbed in proportion to the amount of movement of microorganisms and grows based on both photosynthetic products and metabolic nutrients of microorganisms. Thus, when it produces by this invention, there exists a tendency for the growth and yield of a plant not to change annually, and fertilizer consumption increases significantly at the time of the low temperature of autumn to winter (1.5 to 2 times of normal cultivation).
