    摘要:

    將溫室作物整個生長季節(jié)分為營養(yǎng)生長階段和生殖生長階段。在營養(yǎng)生長階段,，以溫度優(yōu)先為控制策略,，即以溫度為主控參數(shù),，根據(jù)溫室內(nèi)加溫和降溫的幅度等級來選擇相應(yīng)的執(zhí)行機(jī)構(gòu),，實現(xiàn)溫室內(nèi)作物栽培的環(huán)境參數(shù)控制要求,。在作物生殖生長階段,，綜合控制成本模型,、溫室環(huán)境的預(yù)測調(diào)控模型和作物生長模型,，以溫室產(chǎn)出與投入比最大為溫室環(huán)境控制目標(biāo)進(jìn)行決策,，為溫室內(nèi)作物生長提供經(jīng)濟(jì)適宜的環(huán)境參數(shù)和生長條件。以黃瓜為栽培對象,，進(jìn)行了溫室周年生產(chǎn),。實踐表明，按經(jīng)濟(jì)最優(yōu)目標(biāo)的控制策略來實現(xiàn)溫室環(huán)境控制,，既保證了作物正常生長的需要,，又兼顧了經(jīng)濟(jì)成本,。

    Abstract:

    The whole crop cultivation season was divided into two periods, namely vegetative stage to reproductive stage. In vegetative stage, the temperature was taken as a principal parameter, prior to other parameters in greenhouse. According to the corresponding magnitude rank of temperature rising or cooling, actuating mechanisms were carried out to meet control requirements. In reproductive stage, the control strategies were acted as economic optimized methods. Putting control cost models, predicted environmental parameters control model and the crop growth models in unite system to maximize the greenhouse input/output as control objective. So it could create favorable microclimate parameters and conditions to fit crop growth and development. And the system to cucumber round production was carried out. Practices showed that with the control system based on economic optimization strategies to manage crop growth and development, favorable control effects and lower cost were gained.
