Problems solved by technology

[0002] At present, during the planting process, farmers find that crops have diseases and insect pests and then take treatment measures, often resulting in irreparable losses. The traditional control methods are often through expert judgment or laboratory testing. The former requires long-term experience and The accumulation of knowledge can reach a certain height, and there may also be differences in judgments due to individual differences; although the accuracy of the latter has improved a lot, it often requires a relatively long period of detection, and the timeliness is relatively poor

Embodiment 1

[0030] Embodiment 1 illustrates the diagnostic method and application of small rapeseed, and the specific method is as follows:

[0031] Choose a time with clear weather and sufficient sunshine for measurement. Take the fourth-to-last mature and stretched leaf in the inner wheel of a small rapeseed, remove the outer 1-2 old leaves, wash with clean water, dry the surface moisture with absorbent paper, and put it into the press. Squeeze the leaves at the jaws of the juice pliers to make the leaf tissue fluid flow out. After removing the first 5-6 drops of tissue fluid, collect the crop tissue juice into the juice collection box, shake the juice collection box by hand, mix well and drop it into the Check the surface of the prism of the sugar meter, observe the measurement results, and take the average value of three measurements as the standard;

[0032] According to the measurement results, compare them with the Brix evaluation indicators of the corresponding crops in Table 1 to...

Embodiment 2

[0034] Embodiment 2 has illustrated the diagnostic method and application of tomato, and specific method is as follows:

[0035] Choose a sunny and sunny time for measurement, extract the third ear of tomato ripening fruit, remove the fruit skin, put it into the jaws of the juicer, squeeze the fruit skin, let the tissue fluid flow out, and remove the first 5-6 drops of tissue fluid Finally, collect the crop tissue juice into the juice collection box, shake the juice collection box by hand, mix it and drop it on the detection prism surface of the sugar meter, observe the measurement results, and take the average value of three measurements as the standard;

[0036] According to the measurement results, compare them with the Brix evaluation indicators of corresponding crops in Table 1 to determine the nutritional health of tomatoes (poor, up to standard, good, excellent). If the nutritional health of the crop is lower than the standard value, it indicates that the tomato is in a...

Embodiment 3

[0038] Embodiment 3 has illustrated the diagnosis method and the application of apple, and concrete method is as follows:

[0039] Choose a sunny and sunny time for measurement, extract the third ear of apple fruit in the swelling stage, remove the fruit skin, take a representative part of the pulp and put it into the mouth of the juicer, squeeze the fruit skin to make the interstitial fluid flow out, remove the After 5-6 drops of tissue fluid, collect the crop tissue juice into the juice collection box, shake the juice collection box by hand, mix well and drop it on the detection prism surface of the sugar meter, observe the measurement results, and take the average value of three measurements as the standard ;

[0040] According to the measurement results, compare them with the corresponding crop Brix evaluation indicators in Table 1 to determine the nutritional health of apples (poor, up to standard, good, excellent). If the nutritional health of the crop is lower than the...

Abstract

The invention relates to a diagnosis method for a crop nutrition health state. The diagnosis method comprises the steps of detecting a crop brix index, and judging the crop nutrition health state according to the crop brix index. The invention relates to the field of crop health states, in particular to the diagnosis method for the crop nutrition health state. The diagnosis method has the advantages that the diagnosis method is used as an index for measuring the crop health state. The main principle is in a way that the concentration, namely sugar content, of a crop soluble solid is reflectedby measuring a refractive index of a crop tissue liquid, crop with relatively high brix contains higher carbohydrate and mineral content, thus, the risk that the crop is infected with pests is lower,and the disease resistance of the crop is also high.

Description

technical field [0001] The invention relates to the field of crop health status, in particular to a method for diagnosing the nutritional health status of crops. Background technique [0002] At present, during the planting process, farmers find that crops have diseases and insect pests and then take treatment measures, often causing irreparable losses. The traditional control methods are often through expert judgment or laboratory testing. The former requires long-term experience and The accumulation of knowledge can reach a certain level, and there may be differences in judgments due to individual differences; although the accuracy of the latter has been improved a lot, it often requires a relatively long period of detection, and the timeliness is relatively poor. Farmers suffer from the lack of a simple, easy, and relatively reliable on-site prediction method to predict the occurrence of pests and diseases. An intuitive and effective diagnostic indicator is urgently neede...
