Description
Technical field
The invention belongs to plant growth nutrition condition monitoring technical field, particularly utilize normalized differential vegetation index (NDVI) to instruct Nitrogen Application to improve the fertilizing method of nitrogen utilization efficiency and lodging resistance in a kind of Growth of Wheat process.
Background technology
Wheat during jointing stage is that the wheat stalk stalk is grown, and determines the critical period of its mechanical strength.And the organic matter that stores in late growth stage stem stalk decomposes in a large number, is also the key factor that changes stem stalk mechanical strength.A little less than stem end stalk mechanical strength, the plant lodging resistance is low, and final wheat output is badly damaged.According to the study, lodging can cause wheat grain yield to reduce (Vera etc., 2012 more than 30%; Wiersma etc., 2011).Although the wheat scientific worker has done a large amount of work on this problem, attempt to improve the lodging resistance (Wiersma etc. of plant by measures such as breed breeding, cultivation management, change controls, 2011), yet meteorologic factor is fast changing, there is serious Unpredictability in Wheat lodging, also thereby become the global problem (Martinez-Vazquez and Sterling, 2011) that hinders Wheat Production potentiality and nitrogen utilization efficiency lifting.
Lodging mostly occurs at stem culm base internode.On microstructure, basal internode vascular bundle number, diameter, supporting tissue characteristic, cell wall thickness, degree of lignification, catheter wall thickness, bundle sheath thickness, the catheter drive size directly has influence on stem stalk compression strength; Wheat stalk stalk supporting tissue is thick, the cell number of plies is many, the plant center of gravity is lower, basal internode one-dimensional tube bank area and perimeter is large, plant height is close and plant lodging resistant force that under fringe, internode is long and the plant height Composition index is larger large (An Chengfeng etc., 2008).On economical character, Keller etc. (1999) by the wheat genetic collection of illustrative plates structure and the positioning analysis of quantitative character find, stem hardness, thickness and the suppleness of plant, leaf are wide, height and lodging close ties.Make us interested be that base portion the 1st, the structural large molecule of 2 internodes and lodging have close relationship.Crook and Ennos(1995) cell wall constituent of Wheat Cultivars is analyzed, between the discovery kind, there were significant differences for content of cellulose, and the kind that content of cellulose is high is the most resistant to lodging.Berry etc. (2003) studies show that, the hemicellulose of anti-fall kind stem stalk and content of lignin are all higher than not anti-fall kind.Tripathi etc. (2003) find also that by comparing the stem stalk content of lignin of 4 different kinds of lodging resistance the high varietal resistance of content of lignin is strong.Conventional Hormone or growth regulator in production, as chlormequat, help strong element etc. to improve the wheat straw stiffness, yet this type of material causes harmful effect because of residual to succession crop growth, wheat quality, ecotope etc.
Nitrogen is the necessary macronutrient of plant growth fertility, is to affect the most important factor of crop yield.It is chlorophyllous synthetic that nitrogen is participated in crop leaf directly, affects leaf photosynthesis and respiration.Simultaneously, N element nutrition condition also affects crop to the absorption of other nutrition such as the elements such as P, K.Yet during the nearly last ten years, increasing sharply of the fertile consumption of N is increased to present 80kg/ mu by original 40kg/ mu, 100kg/ mu even, and in field ecosystem, the N surplus also constantly increases.Annual consumption N is fertile 87000000 tons in the world, and 60% is used for cereal produces, yet the fertile utilization ratio of cereal N (Nitrogen use efficiency) is only 33%(Alexandratos, and 1995).The fertile availability of N that the excessive N of using fertilizer brings descends, the serious problem of loss also becomes increasingly conspicuous, and more seriously in soil, the NO3-of a large amount of accumulations pollute (huge dawn Chinese bush cherry, 2003) to underground water; On the other hand, in high N growing environment, dissociating in wheat leaf blade, N is corresponding to be increased, inducing the photosynthetic product carbohydrate to be converted into protein trend increases, and affects stem stalk mechanical strength, and the internode meristematic cell is elongated, the cell wall attenuation, thereby plant easily sends out lodging, increase damage by disease and insect incidence (Yu Zhenwen etc., 1995).Long diligent wait (2003) of well also propose, and with the increase of executing the N amount, under basal internode and fringe, the proportioning of internode is inharmonious, and the basal internode circularity is inadequate, and stem stalk C/N ratio is too low, and the Wheat lodging rate is raise, and also therefore becomes the low principal element of wheat N element utilization ratio.Wei Fengzhen etc. (2008) also have similar conclusion, and they study and find that basal internode length and N content all increase with executing the N level, and basal internode diameter, stem stalk wall thickness, mechanical strength show on the contrary; Cell wall Fiber and lignin concentration and the anti-fall index of stem stalk present with the increase of executing the N level and first increase the trend of falling afterwards.Moreover our laboratory and other studies show that, excessive N element suppresses seed germination, seedlings root growth (Britto and Kronzucker etc., 2002; Li etc. 2010; Cheng etc., 2011).
As everyone knows, K is also the macroelement (Szczerb et al., 2008) of plant cell physiological activity, is that in cell, the plurality of enzymes activity is necessary, is carbohydrate, the synthetic important co-factor (Marschner, 1995) of protein.Yet, due to NH
4 +And K
+Exist the similitude of height on the characteristics such as electric charge, molecular size, hydration energy, common transport channel (channels) and Regulation Mechanism (White, 1996) are both arranged, the NH of high concentration on cell membrane
4 +Significantly suppress K+ passage (for example AKT1and HAK5) activity, K
+Absorption rate and the accumulation in plant corpus, and then affect cell physiological activity stable state (Angeles et al., 2005; Szczerba et al., 2008b; Hoopen et al., 2010).And K
+With NO
3 -Exist complementarity on electric charge, K
+Promote root system of plant to NO
3 -Absorption.Therefore plant exists competition and the mutual relation of coordinating to the absorption of three kinds of ions.
Therefore, disposing rationally that N, K element use is to improve wheat straw stiffness, the important channel that strengthens its anti-fall performance.Recently, the handheld portable data collecting system (GreenSeeker Sensor) of the state university in Oklahoma (Oklahoma State University) development is to obtain vegetation index and ruddiness and near-infrared (near infrared by obtaining the crop relevant information; NIR) the crop investigations instrument of the ratio of light.The plant chlorophyll absorptive red light is as the photosynthesis energy, and therefore, healthy plant can absorb more ruddiness, reflects more near-infrared.Standard deviation vegetation index (normalized difference vegetation index, NDVI) be the quantitative target that photosynthesis of plant absorbs effective radiation, be commonly used to plant health state and growth activity, by formula NDVI=(NIRreflected – Redreflected)/(NIRreflected+Redreflected) calculate.GreenSeeker Sensor can make diagnosis according to the NDVI data that remote sensing records to crop growing state, output by the microcomputer analytical calculation of apparatus preparation, and can measure fast, easily and accurately crops in the demand (Raun et al., 2002) of the different times of growing to N fertilizer.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of new fertilizing method.The present invention is by detecting the overall target of wheat growth and nutrition condition---and normalized differential vegetation index (NDVI) value instructs the management of nitrogen real-time on-site, improves wheat lodging resistance and nitrogen utilization efficiency.
