Technical Field
The invention relates to the technical field of agriculture, in particular to a device and a method for collecting rhizosphere secretion of capsicum.
Background
In the pepper growth process, the rhizosphere not only takes up nutrients and moisture from the environment, but also secretes protons into the growth medium, releases inorganic ions, and overflows or secretes a large amount of organic matters. Together, these materials and root tissue casts are collectively referred to as root products, i.e., root secretions. As early as 18-19 th century, growth promotion and inhibition of adjacent plants by rhizosphere secretions was observed. However, until the 50 s of the 20 th century, studies in this field have become abnormally active as the relationship between rhizosphere secretions and nitrogen fixation, etc., which promote plant growth, and the relationship between rhizosphere secretions and the growth of living beings, etc., have been gradually recognized.
In the research work of the chilli rhizosphere secretion, the traditional rhizosphere secretion collecting method is to take the plant rhizosphere out of the cultivation soil directly and then rinse the plant rhizosphere with distilled water, the eluting solution is used as the rhizosphere secretion, the rhizosphere is extremely easy to damage in the whole operation process, the rhizosphere secretion is mostly absorbed by soil at the position below the plant rhizosphere, the rhizosphere secretion attached to the extracted rhizosphere is less, and the experimental result can be influenced under the condition of mixing a large amount of other impurities.

the utility model discloses a culture box, including cultivate box (1), including annular piece (22) of box (1), annular piece (22) of box (1) lower extreme fixedly connected with in the outside position of collection tube (13), be equipped with annular pipe (23) in annular piece (22), annular piece (22) upper end be equipped with a plurality of drain heads (24) with annular pipe (23) upper end intercommunication, annular pipe (23) lower extreme intercommunication has annotate liquid pipe (25), annotate liquid pipe (25) lower extreme and run through the interior bottom wall setting of cultivate box (1) and be equipped with annotate the liquid head, annotate and be equipped with check valve (26) on liquid pipe (25).
2. The pepper rhizosphere secretion collecting device according to claim 1, wherein a fixing frame (2) is fixedly sleeved on the outer side of the culture box (1), and four supporting legs (3) are fixedly connected to the lower end of the fixing frame (2).
3. A method for collecting the rhizosphere secretion of capsicum according to any one of claims 1 to 2, comprising the steps of:
s1, pouring cultivation soil into a culture box (1), pouring pepper seeds when the cultivation soil is half of the height, pushing up a collecting cylinder (13), enabling a collecting hopper (14) to be close to the pepper seeds, and then filling the cultivation soil;
s2, after the pepper seeds are planted, sequentially rotating four threaded rods (7) through four rotating blocks (8), and pushing corresponding limiting frames (4) to move by utilizing a moving plate (6) and a push rod (5), so that the four limiting frames (4) are arranged in a rectangular shape to surround the pepper seeds;
s3, after the chilli seeds are surrounded by the limiting frame (4), water can be added into the water storage hopper (12), and enters the water pipes (9) and is absorbed by the water absorption sponge (11), so that water seepage from four directions into the cultivation soil is facilitated;
s4, injecting a culture solution into the annular pipe (23) through the liquid injection pipe (25), so that the culture solution permeates into the cultivation soil from the bottom of the cultivation box (1) to provide growth nutrients for the rhizosphere of the peppers;
s5, after growing rhizosphere along with the capsicum seeds, periodically pulling down the collecting cylinder (13), and using the pull rod (20) to move the connecting rod (17) upwards during the period, so that the soil pulling rod (18) jacks up the baffle plate (15) and enters the collecting hopper (14), then pulling down the pull rod (20) to move the soil pulling rod (18) downwards, so that the cultivation soil at the top of the inner side of the collecting hopper (14) is pulled into the collecting cylinder (13) and falls onto the lower soil receiving disc (21), and the process is repeated, so that a certain amount of rhizosphere soil is collected;
s6, separating secretion in rhizosphere soil.
