Loss Rate Estimation of Yield and Output Value of Tobacco Leaf Infected by Tobacco Blown Spot (Alternaria alternata)

[Objective] The paper was to study the effect of tobacco blown spot on the yield and output value of tobacco leaf.[Method]The upper,middle and lower leaves in tobacco plant were selected during the harvest period of tobacco to carry out loss rate estimation of yield and output value of tobacco leaf caused by different disease levels of brown spot.Regression correlation analysis was also conducted.[Result]The disease levels of brown spot had extremely significant strong negative correlation with single leaf weight of tobacco leaf,and it had extremely significant strong positive correlation with the loss rate of single leaf weight.The increase speed of loss rate of single leaf weight of middle and upper leaves was obviously faster than that of lower leaves.The loss rates of single leaf weight of upper,middle and lower leaves were 3.18%-28.95%,3.43%-28.88% and 10.07%-26.90%,respectively.The higher the disease level of blown spot was,the lower the yield and output value of tobacco leaf was,and the corresponding loss rate was also higher.Correlation analysis showed that the disease level of blown spot had extremely significant strong negative correlation with the yield and output value of tobacco leaf,and it had extremely significant strong positive correlation with the loss rate of yield and output value.The negative impact of blown spot on the output value of tobacco leaf was far greater than that on the yield.The highest loss rate of the yield of tobacco leaf was 28.56%,while the highest loss rate of output value reached 89.67%.[Conclusion] The study provided theoretical basis for accurately holding the critical period for the control of blown spot,thus reducing the damage on tobacco leaf and improving the output value of tobacco leaf.

Effects of Different Tillage and Mulching Modes on Tobacco Output Value and Soil Quality

Based on three years of long-term fixed-site field trial, the effects of differ- ent tillage and mulching modes on the yield and output value of tobacco and soil quality were investigated. The results showed that the yield and output value of to- bacco in tillage treatment were improved by 22.72 % and 37.23 % compared with non-tillage treatment, respectively; the yield and output value of tobacco in rotation treatment were improved by 1.83% and 19.41% compared with continuous cropping treatment, respectively; the yield and output value of tobacco in straw mulching treatment were improved by 3.55% and 2.4% compared with non-straw mulching treatment, respectively, which indicated that tillage, rotation and straw mulching could improve the yield and output value of tobacco to a certain extent; especially, the yield and output value of tobacco increased significantly after plowing under rotation conditions. The contents of available phosphorus （AP）, alkali-hydrolyzable nitrogen （AN）, organic matter （OM）, total nitrogen （TN） and total phosphorus （TP） in non- tillage treatment were 35.14%, 9.92%, 9.57%, 4.40% and 34.16% higher compared with tillage treatment; especially, under non-tillage conditions, soil pH and contents of available potassium （AK）, AP, AN,OM,TN,TP and total potassium （TK） in continu- ous cropping field were 2.01%, 48.68%, 73.09%, 11.45%, 7.71%, 7.31%, 47.68% and 11.78% higher compared with rotation field, indicating that non-tillage treatment and continuous cropping could improve the total content and available content of organic matter, nitrogen and phosphorus. Therefore, from the perspective of soil fer- tility improvement and sustainable tobacco production, continuous cropping under non-tillage conditions might be the most appropriate cropping pattern for local soil fertility improvement; aiming at improving the yield and output value of tobacco, green manure-tobacco→, green manure/wheat/maize→green manure-tobacco ro- tation might be the most appropriate cropping pattern.

Effects of Different Biochar Dosages and Types on Growth, Yield and Output Value of Flue-cured Tobacco in Hanzhong Area

[Objective] This study was to investigate the effects of different biochar dosages and trpes on growth, yield and output value of flue-cured tobacco in Hanzhong. [Methods] In May-September of 2013, Xiaonanhai Town, Nanzheng County, Hanzhong City, a field experiment was carded out to study the effects of- biochardosage and type on tobacco agronomic traits, yield and output value in each growth period. [Results] Biochar application significantly increased plant height, stem diameter and leaf size in the early growth pedod, and raised tobacco yield, output value and the proportion of high grade leaf： With the increase of biochar dosage, tobacco agronom~ traits were significantly improved, and yield, output value and proportion of high-grade tobacco leaves also increased significantly, and the highest tobacco yield and output value occurred at the dosage of 900 kg/hm2. Agronomic traits of tobacco leaves with the application of rice husk char and wheat straw char were significantly better than those with the application of peanut shell char, appli- cation of rice husk char was more conducive to the development of leaves in the vigorous pedod and stems in the squaring period, but straw char was beneficial to improvement of plant height and leaf number in the vigorous period and leaf growth in the squaring period, and application of rice husk char had the best effect on the increases of yield and output value of tobacco leaves. [Conclusion] Application of biochar is an effective measure forimproving tobacco-planting soil and promoting the growth and development of tobacco in Hanzhong, biochar application amount should be controlled at about 600-900 kg/hm2, and rice husk char is the preferred choice as soil improvement material.

Research on Agricultural Economic Development under the Background of Urbanization

Agriculture is the basic industry of China and the support of all other industries. In order to clarify the impact of urbanization on China＇s agriculture, a cointegration test was conducted between the urbanization rate and the total agricultural output value in China during the past 30 years of 1986-2015. The results showed that the development of urbanization and agricultural economy had no severe effect on weakening the agricultural economy in China, while on the contrary, there was a long-term equilibrium relationship between the two, which was only limited to a certain range, and in the future high development of urbanization of China, the development of agricultural economy would face great challenges. Therefore, China should specify cultivated land use, strengthen the supervision standard of land circulation; increase investment in science and technology, improve the efficiency of agricultural output; optimize financial support for agriculture, enhance the enthusiasm of farmers; cultivate new agricultural operators, promote the process of agricultural industrialization, so as to form economies of scale and explore a new road of urbanization which is not at the expense of the cost of agricultural economy.
