Diagnosis of crop nutrient balance and regulation system


Rice nutrient database. The establishment of the database after 10 years, including the plots of 100 or more. Each sample of each of the nutrient concentration and ratio between the mean and the coefficient of variation calculated in accordance with the process of growing period to be arranged, they form the dynamic model of plant nutrient, which is high and ultra high-yield rice nutrient standard value, Tin is also used for diagnosis of production standards. In order to enrich the nutrient database, nutrient dynamics model more practical, the plant nutrients into different sequences,[link widoczny dla zalogowanych], that whole plant nutrients, nutrient, nutrient leaf sheath, internode and ear nutrient nutrients. The actual diagnosis, as long as the plots were diagnosed samples of all parts of the plant nutrients in the laboratory analysis came out, then stored in the computer with the corresponding parts of the standard value for diagnosis. In order to diagnose accurately and quickly diagnose crop nutrient balance and nutrient-conditioning system also has automatic data processing, computer software, the system features include; a. Experimental data on-screen editing, b. Nutrient ratios and nutrient index sample algorithm program, c. Nutrient regulation scheme for computer program, d. Sampling procedures for multivariate statistical analysis algorithm; e. Report output. l,, L. 2. System to determine the number of diagnostic indicators for the comprehensive and accurately reflect the nutritional status of crops, making operation simple and accurate diagnosis, new diagnostic criteria of selection should not only put all the factors that may affect the production (including the crop, soil and other environmental factors ) and the separate effects of quantitatively established to consider, and should the crop, soil, and the relationship between environmental factors and their relationship with yield to be taken into account, that is, we should output from the field fertilization to the formation of various intermediate mathematical methods used to make the process of the said amount, that is. [Soil reaction + climate + management + root outside the fertilization] reaction to yield a crop. Under the influence of various environmental conditions, the response of a variety of crops,[link widoczny dla zalogowanych], such as plant height and tiller number of changes in leaf color, and changes in leaf area, and the nature of the response is the body of the plant nutrient concentration and ratio between I1-1��X (i +1) x index = broad elements of an index such as nitrogen. Changes. But because of plant nutrient concentration integrated response to the external environment of physiological indicators, more essential meaning and relative stability, and some form of indicators not have such features. Comprehensive description of crop response indicator is the Nutrient index taken into consideration both plants the content of nutrient elements, but also special attention to the relationship among elements, and their range of variation. Nutrient index can be integrated, faithfully reflecting the nutritional status of crops was, unlike so many morphological characters have a strong chance and uncertainty. 3. Mathematical expression by nutrient index field sampling and laboratory analysis, has been a crop of nitrogen, phosphorus, potassium, calcium, magnesium,[link widoczny dla zalogowanych], sulfur, iron, manganese, copper, zinc and boron content of 11 elements in the data, then any element x, nutrient index is calculated as follows. Where: n = 11, as the number of elements X (i +1) = f [X / Y (i +1)] or a = a f [Y (i +1)) N index =- f (N- / P-) +-f (-N/-K) - + f-(N per / Ca d) - f (M-g/-N )-+--. . + A f (N / B) where: f (N / P) = (} I) or. r (NIP) = (a) N / P ratio for the sample of actual nitrogen and phosphorus, expressed as a percentage; N / P to the same standards for nitrogen and phosphorus than the growth period, from high-yield model provides, C. V as the standard ratio of coefficient of variation. The same method available to other elements of the nutrient index. Nutrient Index can range from any negative to zero, and from zero to any positive value. Index of zero, indicating that the amount of nutrient concentrations, and other elements in the system and the ratio in balance, the index is negative, indicating that the nutrient deficiency, the index is positive,[link widoczny dla zalogowanych], it means that the nutrients in excess. Whether positive or negative index,[link widoczny dla zalogowanych], the absolute value farther from zero nutrient imbalance is that the more serious. Obviously, when we have calculated the index of the elements came out, 2 (N / P> N / P when) (N / P <N / P time) is easy to yield to them the importance of discharge order. Index of plant nutrients in the growth period of any part of any effective diagnosis and from the weather and geographical variations. Very high due to nutrient sensitivity index, so both can be used in low-yielding fields in the barriers on the diagnosis and accurately identify the major elements to limit production, but also particularly suitable for preventive diagnosis of high-yield field, quickly found by potential can not be found directly limiting factor to overcome the blindness of fertilizer to promote and increase crop yield significantly more productive.
