DEVICE FOR RAPIDLY DIAGNOSING POTASSIUM NUTRITION OF
POTATOES USING PORTABLE POTASSIUM ION METER, AND METHOD
FOR RECOMMENDING POTASH FERTILIZER
[01] The present disclosure belongs to the field of agriculture, and in particular relates to a device for rapidly diagnosing potassium nutrition of potatoes using a portable potassium ion meter, and a method for recommending potash fertilizer.
[02] As a potassium-loving crop, the potato has a greater absorption of potassium than any other mineral element. A large number of researches have shown that inadequate supply of potash fertilizer to potatoes results in slow plant growth, underdeveloped root systems and reduced tuber yields, and when the the potash fertilizer application rate is increased to a certain degree, the biomass and the yield of the potato plants are not increased any more accordingly. However, some researchers have found that the potassium absorption of the plants continues to increase accordingly, it is proved that the potatoes have luxury potassium absorption; meanwhile, when excessive potash fertilizer is applied, negative effects such as deterioration of tuber processing quality, waste of potassium ore resources and the like may be generated. Therefore, the potato production requires accurate and scientific management of potassium nutrition through plant potassium nutrition diagnosis.
[03] In the traditional method for plant potassium nutrition diagnosis, a flame photometer 1s mainly used for determining potassium nutrition content in plant tissues.
According to the method, the nutritional status of crops can be directly and accurately reflected, and the nutritional abundance and deficiency can be then determined.
However, there are still the following problems: in the process from field sampling to laboratory drying, grinding and digestion of samples, and then to determination and analysis, an amount of time is consumed, the diagnosis timeliness is poor, and during production, the potassium nutritional status of potato plants cannot be evaluated in real time, and fertilizer application cannot be guided in real time.
[04] For the problems, an objective of the present disclosure is to provide a device for rapidly diagnosing potassium nutrition of potatoes using a portable potassium ion meter, which can rapidly and conveniently determine petiole potassium concentration of the potatoes in real time in the field, and then judge potassium nutritional abundance and deficiency status of potato plants, thus achieving real-time recommendation of potash fertilizer application rate for the potatoes.
[05] To achieve the objective, a technical solution adopted by the present disclosure for solving the technical problem is as follows: a device and a method for rapidly diagnosing potassium nutrition of potatoes using a portable potassium ion meter are provided, the device comprises a fixed frame arm (1), a fixed frame base (2), a juicer (3), connecting rings (4), a taper hopper (5), a water inlet pipe (6), a graduated tube (7), a valve (8), a juice outlet pipe (9), a potassium ion meter (10), and a stirring needle (11); the fixed frame arm (1) is connected to the fixed frame base (2) and is made of steel; the fixed frame arm (1) is in an inverted L shape, and the upper end thereof is provided with the juicer (3); the juicer (3) is arranged at the upper end of the fixed frame arm (1); the connecting rings (4) are welded to two sides of the bottom of the juicer (3) for fixing the taper hopper (5); the water inlet pipe (6) is arranged above the graduated tube (7), the graduated tube (7) has a volume of 10 mL, is made of polypropylene, and is precisely marked with scale lines on the tube wall; the graduated tube (7) 1s placed on the fixed frame base (2) and capable of moving left and right, and the valve (8) and the juice outlet pipe (9) are arranged at the lower right of the graduated tube; and the potassium ion meter (10) is arranged right below the juice outlet pipe (9).
[06] A diagnosis method comprises the following steps:
[07] 1) detection of petiole potassium concentration: within 15-75 days of seedling emergency of potatoes, randomly selecting 30 potato plants with the same growth vigor and without plant diseases and insect pests on the day Ed, cutting off reciprocal fourth compound leaves and reciprocal eighth compound leaves (the fourth (L4) and the eighth (L8) completely unfolding leaves of the topmost parts of the main stems from top to bottom) on the main stems by scissors, removing leaves on the petioles, and continuing to employ the petioles, placing the L4 petioles and the L8 petioles in the juicer (3) respectively, enabling extracted juice to flow into the graduated tube (7) through the taper hopper (5), the extracted juice having a volume of 1 ml; arranging the water inlet pipe (6) above the graduated tube (7), stopping adding distilled water after the distilled water (6) flows into the graduated tube (10) from the water inlet pipe (6) to the mark of 10 ml; placing the stirring needle (1) in the graduated tube (7) for uniformly stirring; arranging the potassium ion meter (10) right below the juice outlet pipe (9), opening the valve (8) to make the uniformly stirred juice flow into the potassium ion meter (10) from the juice outlet pipe (9), determining in real time and recording the reading number, and conversing according to dilution ratios to obtain actual potassium ion concentrations of the tested petioles.
[08] 2) Judgment of potassium nutritional abundance and deficiency of potatoes: calculating a petiole potassium concentration difference of L4 and L8: AKct=Kc(L4-
L8), substituting the day Ed into a critical value equation of the petiole potassium concentration difference (AKc'=-0.0029Ed?-12.623Ed+1154.9) to calculate AKc', if
AKct>AKc', no potash fertilizer needing to be applied; (the critical value equations are shown in the attached FIG. 2 and 3).
[09] 3) Recommendation of potash fertilizer application rate for potatoes: if AKct <
AKc', substituting AKct, AKc’ and Ed into a suggested potash fertilizer application rate equation [Kr=(AKc'+1154.9-AKct):(-5x105Ed?+0.0145Ed+ 0.6567), Kr is the suggested potash fertilizer (K20) application rate (kg-hm™)] to calculate the suggested potash fertilizer application rate. (The potassium fertilizer suggested application rate equation is as shown in FIG. 4).
[10] The present disclosure has the beneficial effects that the petiole potassium concentration of the key leaves (the reciprocal fourth leaf and the reciprocal eighth leaf which are the fourth and the eighth completely unfolding leaves of the topmost part of the main stem from top to bottom) can be rapidly and conveniently determined in real time within 15-75 days of seedling emergence of potatoes by means of a device for rapidly diagnosing potassium nutrition of potatoes using a portable potassium ion meter and a method for recommending potash fertilizer, the potassium nutritional abundance and deficiency of the potato plants can be judged by comparing the petiole concentration difference of the L4 and L8 with a critical value, and then the potash fertilizer application rate can be calculated according to the potash fertilizer recommendation equation; the problems of poor time-effectiveness of potassium nutrition diagnosis for potatoes and potash fertilizer recommendation are effectively solved, and an important practical significance is achieved for high yield of the potatoes and efficient utilization of the potash fertilizer.
