The paper reviewed the recent work on the computer simulation ofthe crop growth, described a computer mode!-PENUTZ, for simulatingpeanuts growth. Based on the PENUTZ, the authour worked out a simpleBASIC program for peanut growth simulation-PENUTMOD, which canrun on a SHARP PC1500 pocket computer. PENUTMODB responses tovaries input radiation, temperature and precipitation data, calculatescumulative radiation, heat unit, soil water content, moisture stressfactor, ground cover rate, total cumulative dry weight,...

PENUTMODB responses tovaries input radiation, temperature and precipitation data, calculatescumulative radiation, heat unit, soil water content, moisture stressfactor, ground cover rate, total cumulative dry weight, pod dry weightand indicates whether irrigation is needed. PENUTMODB should be testedwith local data.

本文概述了作物生长计算机机模式的内容、原理、特点及国外研究概况,介紹了国外已开发的花生生长计算机模式PENUTZ的基本框图及其主要内容。按照PENUTZ的基本原理,作者试编了一个能在SHARP PC1500袖珍计算机上运行,并用BASIC語言写成的簡化花生生长模式PENUTMODB,这一程序能模拟不同光、温、水条件下花生干物质、地面覆盖度、莢果干重的增产动态,預测物候期及产量。文中对其基本结构和运算步驟作了說明。PENUTMODB将在生产或试验条件下检验其准确度和灵敏性。

The present work is the continuation of the experiment inaugurated in 1983. The model constructed in 1983 for the growth of various organs of the rice plant is solved by means of the trapezoidal method, resulting in a recurrence formula which described the processes of rice growth and yield formation. Preliminary investigation is also made on the assimilative ability, the assimilator distribution and the transition of the rice population. Optimal solutions of the model parameters are determined through optimization....

The present work is the continuation of the experiment inaugurated in 1983. The model constructed in 1983 for the growth of various organs of the rice plant is solved by means of the trapezoidal method, resulting in a recurrence formula which described the processes of rice growth and yield formation. Preliminary investigation is also made on the assimilative ability, the assimilator distribution and the transition of the rice population. Optimal solutions of the model parameters are determined through optimization. Also simulated are the processes of rice growth and yield formation in 1984.

本文在1983年试验研究的基础上,进一步探讨了水稻生长与产量形成的数值模拟方法。对1983年试验建立的水稻叶、茎、根、穗等器官生长模式用梯形近似法求解得出描述水稻生长和产量形成过程的递推表达式;对水稻群体同化能力、同化物分配转移规律也进行了初步研究;并用最优化方法确定出模式参数的最优解,模拟了1984年水稻生长发育和产量形成过程。

A series of experiment for the high yield of wheat production with minimum or no-tillage was carried out in the harvested rice field in the Huai Rive rwgions of Jiangsu from 1983 to 1987. The results indicatcd that the wheat seedling with minimum or no-tillagc grows rapidly at early stage, most of the root scattered in the surface soil (0-7cm), senescence often appeared during the middle to late stage, the formation or the high yield population were summarized quantitatively as follows: production has to synchronize...

A series of experiment for the high yield of wheat production with minimum or no-tillage was carried out in the harvested rice field in the Huai Rive rwgions of Jiangsu from 1983 to 1987. The results indicatcd that the wheat seedling with minimum or no-tillagc grows rapidly at early stage, most of the root scattered in the surface soil (0-7cm), senescence often appeared during the middle to late stage, the formation or the high yield population were summarized quantitatively as follows: production has to synchronize the wheat physiological stages and the growing season, the tiller numbers and the developmental stagc, and LAI and dry material and the devolopment. In order to realize the models, the corresponding techniques included, (1) sowing method of minimum or no-tillage and the related techniques are established in accordance with the prcceding crop and soil moisture during the optimum sowing time; (2) the quantity of presowing and seedling fertilizer are determined based on the soil productivity, soil-supply and growing-demanding, and the quantity and applying time for the ear-developmant fertilizer are determincd based on growing situation; (3) the lodging during the late stage and weeds are controlled by the agronomic technique and the chemicals.

1983-1987年在江苏淮南地区稻板茬上进行一系列试验表明:少免耕小麦具有早发、根量较多集于表土、中后期易脱力早衰等特性。其高产群体的形成可从下列方面数量化地归纳成生长模式:小麦生理年龄与季节进程优化同步;茎蘖动态与生育进程优化同步;LAI及干物量依生育进程合理发展。模式的调控,首先应在最佳播种期内,据茬口、墒情优选少免耕播种方式与配套播种程序;其次据供肥需肥特性,因土确定基、追肥数量,按苗类决定拔节孕穗肥施用时期与数量;并还以化学措施与农艺结合的方法控制草害与小麦倒伏。
