Response Of Ginger To Compound Sodium Nitrophenolate And DA-6

Ginger (Zingiber officinale Rosc.), perennial crops, is a kind of rhizome of products of vegetable crops, and its growing season length, nutrient demand, if cultivated properly managed, can easily result in premature aging or leggy plants. Thus, by proper application of plant growth regulators regulate its growth and development process to improve yield and quality of ginger has important significance. To this end, we study a new type of plant growth regulator compound sodium nitrophenolate and DA-6 (N, N-diethyl aminoethyl hexanote) on ginger growth, yield and physiological characteristics, the main results are as follows:1 Studied with the design of quadratic saturation D-optimal regression, and established a mathematical model, in which sodium nitrophenolate and DA-6 were independent variables and ginger yield was dependent variables. Through analysis of the model, the results showed that sodium nitrophenolate and DA-6 could significantly enhanced ginger yield, but the interaction of them was negative, which showed that sodium nitrophenolate and DA-6 could not be mixed to apply to ginger. In this experimental conditions, the appropriate amount of single application of sodium nitrophenolate and DA-6 were 387 and 303 g/667m~2, respectively, with the yield of ginger were 3118.60 and 3092.95 kg/667m~2, respectively, and the yield increased by 26.59% and 25.55% compared with the control, respectively.2. Adding the soil, respectively, sodium nitrophenolate 400 g/667m~2, DA-6 300 g/667m~2, were significant for the growth of ginger plants, ginger yield improved results. Ginger root growth early in order to promote the most significant effect, but as growth progresses, the fresh weight of plant organs were significantly higher than the control. Ginger harvest, the compound sodium nitrophenolate, DA-6 processing plant height was increased by 11.59% and 14.02% respectively, the number of branches increased by 24.59% and 28.69%, yield increased by 18.53% and 22.30%, but nitrophenolate sodium, DA-6 was no significant difference between the treatments. In addition, the compound sodium nitrophenolate, DA-6 also increased to varying degrees, ginger rhizome starch, soluble protein and amino acid content, and improved quality.3 Adding sodium nitrophenolate and DA-6, can significantly increase the ginger's chlorophyll content and photosynthetic rate, in the ginger's strong growth period, compound sodium nitrophenolate, DA-6 treatment, respectively, chlorophyll content ginger CK higher than 4.58%, 17.97%, photosynthetic rate increased by 14.40%, 20.45%. Ginger swollen late sodium nitrophenolate, DA-6 root activity were 51.2% higher than CK, 66.7%. Ginger leaf nitrate reductase in September reached the maximum when, DA-6, were treated with sodium nitrophenolate CK higher than 30.1%, 20.8%.4 By soil analysis of etiolated ginger's region to determine the ginger etiolated leaf is mainly due to soil nutrient imbalances, manifested as lower the total available nutrient, trace element Zn in particular, lack of available zinc content of soil 1.4 mg/kg only about less than 1.5 mg/kg threshold, excluding the pH is generally accepted that high salt causes discomfort or etiolated ginger leaves the point of view. Etiolated ginger plant nutrient content is generally low, in which zinc significantly different roots, stems and leaves of plants of zinc content lower than the normal 85.2%, 50.5%, 15.9%.5 Through the etiolated ginger leaves applied field by different fertilizers, different degrees of increased leaf chlorophyll content, and promote the growth of ginger, an increase of 24.1%-46.1% range, of which zinc sulfate 6 kg/667m~2. Adding the best, yield rate of 46.1%, followed by 15 kg/667 m~2 ZnSO4, followed by 15 kg/667 m~2 MgSO4, an increase rate of 38.0%.Compound sodium nitrophenolate and DA-6 can significantly reduce the symptoms of etiolated ginger, by Adding Sodium nitrophenolate 200,400 g/667m~2, DA-6 200,400 g/667m~2, chlorophyll content increased 3.24-3.93 times and carotenoid content increased by 2.35-2.77 times, of which 400 g/667m~2 best, nearly normal chlorophyll content ginger leaves. Adding 200,400 g/667m~2 compound sodium nitrophenolate, 200,400 g/667m~2 DA-6, yields were up to 3050.5 kg/667m~2, 3295.1 kg/667m~2, 3303.8 kg/667m~2 and 3802.8 kg/667m~2, respectively, compared with the control 32.0%, 42.6%, 42.9% and 64.5%.
