土壤墑情測定儀 我有新說法
195 0

土壤墑情測定儀是用來測量土壤墑情參數(shù)的儀器。土壤墑情監(jiān)測站常用的有管式土壤墑情監(jiān)測站和探針式土壤墑情監(jiān)測站兩種。根據(jù)可以監(jiān)測土壤的深度不同，對應的型號分別為管式【JD-GTS03】、【JD-GTS04】、【JD-GTS05】、【JD-GTS06】、【JD-GTS10】和探針式【JD-TS400】、【JD-TS500】、【JD-TS600】等。

　　一、產(chǎn)品簡介

　　土壤墑情測定儀是用來測量土壤墑情參數(shù)的儀器。土壤墑情監(jiān)測站常用的有管式土壤墑情監(jiān)測站和探針式土壤墑情監(jiān)測站兩種。根據(jù)可以監(jiān)測土壤的深度不同，對應的型號分別為管式【JD-GTS03】、【JD-GTS04】、【JD-GTS05】、【JD-GTS06】、【JD-GTS10】和探針式【JD-TS400】、【JD-TS500】、【JD-TS600】等。

　　二、常見的土壤墑情測定儀有以下幾種：

　　重力培養(yǎng)法：重力培養(yǎng)法是一種常規(guī)的土壤墑情測定方法。它通過稱量取出的土壤樣品，并在不同時間間隔內(nèi)稱量樣品的質(zhì)量變化，來計算土壤水分含量。

　　干燥法：干燥法是一種通過將土壤樣品置于高溫下，使其失去水分并測量質(zhì)量變化的方法。它適用于粘性較大的黏土質(zhì)土壤。

　　電阻率法：電阻率法是一種利用土壤的電導率變化測量土壤水分含量的方法。它可以快速測量土壤墑情參數(shù)，但受到環(huán)境濕度、溫度等因素的影響較大。

　　折射儀法：折射儀法是一種通過測量土壤與空氣之間光線的折射率變化，來推斷土壤水分含量的方法。它具有快速、準確的特點，可以對土壤進行實時監(jiān)測。

　　高頻振蕩式墑情儀：高頻振蕩式墑情儀是利用高頻振蕩原理，通過測量土壤中水分引起的介電常數(shù)變化來推斷土壤水分含量的儀器。它精度高、穩(wěn)定性好，適合進行連續(xù)、長期監(jiān)測。

　　三、應用選擇

　　這些土壤墑情測定儀可以根據(jù)不同的需求和應用場景選擇使用。同時，它們需要合理保養(yǎng)和維護，以確保數(shù)據(jù)的準確性和儀器的長期使用壽命。
