Under the environment with LED light source in plant factory，taking cucumber‘ Zhongnong No.26’ as test material, this paper studied the effects of different substrate water content on cucumber seedling growth characteristics and water requirement regulation．The results showed that the plant height，stem diameter，biomass，root system morphology index and strong seedling index, etc. of cucumber seedlings were the best when the substrate water content was 85%-90%．The total water consumption of seedling treated with 85%- 90% substrate water content was the highest，reaching 129.72 mL；and the seedling water use efficiency was significantly improved．The relationship between the number of days after sowing and water consumption quantity was the best based on the linear equation．The expression was y=0.355 3 x-1.887 5．Considering comprehensively the growth and water consumption characteristics of cucumber seedlings，under the environment with LED light source，85%-90% substrate water content could cultivate high-quality and strong seedling while achieving high efficient water usage．
In order to explore the efficiency of spraying exogenous substance at leaf surface in enhancing the storage and transport（ST）quality of cucumber seedlings，this paper investigated the effect of Oligosaccharides， Zhuangmiao No.1 and plant perplex on the quality of cucumber seedlings on 0，3 and 6 days after ST．The results showed that Zhuangmiao No.1 could control seedling overgrowing，increase root dry weight and maintain higher seedling index，specific leaf weight and leaf chlorophyll content．While，the effects of Oligosaccharides and plant perplex on various growing indexes of seedling were very limited．Therefore，we recommend spraying Zhuangmiao No.1 at leaf surface to improve the quality of commercial cucumber seedling after ST．
Under solar greenhouse condition，taking LED plant growth lamp（red and blue 7∶2）as complementary light source，this paper studied the effects of different filling hours（1，2，3 hours）on tomato growth，yield and quality. The results showed that compared with the control（without light supplementation）， both 2 and 3 hours could significantly increase the plant height，stem diameter and leaf areas of tomato. Filling 3 hours could significantly improve the single fruit weight，fruit number and yield，contents of fruit VC，soluble sugar，and sugar-acid ratio. The yield was increased by 7.0%，and profit increased by 7 933.5 yuan·hm-2. In summary，supplemental light for 3 hours has the best effects on promoting tomato growth，increasing yield and improving fruit quality.
Taking the winter-spring season cucumber seedlings in the solar greenhouse as experimental material，this paper studied the effects of different supplementary light intensities on the quality of cucumber seedlings． The results showed that the light treatment could effectively reduce the seedling hypocotyl length and plant height， but significantly increase the stem diameter，leaf area，specific leaf weight，dry matter content，and strong seedling index．Moreover，supplementary light could facilitate the distribution of dry matter to leaves and roots，while restrain to stems．In addition，the contents of chlorophyll，carotenoid and starch in seedlings under supplemented light were higher than those of the control，but the soluble sugar content was lower than that of the control．Taking the strong seedling index as criterion of good and bad supplementary treatment，it could be seen that T（100），T（150），and T（200） treatments were significantly superior to the control and T（50）treatment．Thinking comprehensively from the aspects of economy and energy-saving，we recommend supplementary light intensity as 100 μmol·m-2·s-1．
Taking tomato variety‘Fenheping’and tillering onion variety‘Suihua’as experimental material，this paper studied on the effects of tillering onion associated with reduced phosphorus treatment on tomato growth，photosynthetic indexes and yield．The results indicated that the stem diameter in the treatment of tomato inter-cropped with onion under reduced phosphorus condition（50% of conventional phosphorus fertilization） 30 days after planting was significantly thicker than that of the control（tomato monoculture and conventional phosphorus fertilization）．Plant dry and fresh weights were also significantly higher than that of the control at the seedling pulling stage. In addition，the photosynthetic rate，stomatal conductivity and transpiration rate of leaves were obviousely higher than that of control during flowering period and fruiting period．Moreover，tomato single plant yield was significantly higher than that of the control，indicating that tillering onion associated with tomato cultivation could reduce the application rate of phosphate fertilizer．
Taking‘ sand∶slag=2∶1（V∶V）’formula as the CK，this experiment added different volume of mushroom residue with 10%（T1），20%（T2），30%（T3），40%（T4）and 50%（T5）on this basis，and studied the effects of combined substrates of sand，slag and mushroom residue on the yield and quality of eggplants. The results showed that in winter-spring crop，the contents of soluble sugar and free amino acid in eggplant pulp were significantly higher than that of the CK under T3 treatment. The content of ascorbic acid in eggplant pulp under T4 treatment was significantly higher than that of the CK. The contents of anthocyanin，flavonoids and total phenol in eggplant peel were also higher. In autumn-winter crop，the contents of soluble sugar，soluble protein and free amino acid in eggplant pulp were significantly higher than that of the CK under T3 treatment. The ascorbic acid content was significantly higher under T4 treatment. The contents of flavonoids and total phenol in eggplant peel were significantly higher under T1 treatment. In both crops，the yield of T1 treatment was the highest， increased by 5.5% and 11.2% than those of the CK，respectively. In summary，adding 10% mushroom residue was most favorable for the yield forming of eggplant in both winter-spring and autumn-winter crops. While adding 30% or 40% mushroom residue were favorable for the fruit quality forming of eggplant.
Adopting the method of returning nitrogen quantitatively in pot cultivation，this paper studied the effects of returning tomato straw directly to field and returning it to field after compost treatment on tomato growth，yield，fruit quality，soil carbon and nitrogen contents，and enzyme activity. The results showed that the direct returning method could inhibit tomato plant growth within 60 days after returning to field. The Inhibition was weakened 60 days afterward. After 110 days directly returning to field，the tomato plants growth was stimulated， fruit quality was significantly improved and contents of total carbon and total nitrogen，C/N ratio were all increased. Tomato straw compost continued to promote the growth of tomato plant，tomato yield was significantly increased， and contents of total carbon and total nitrogen，C/N ratio and activities of urease and sucrase were all significantly increased. In production，tomato straw compost can be directly applied as fertilizer，and its fertilizer efficiency is better than that of the chicken manure. But，the direct returning of tomato straw to field requires at least 60 days decomposition period to decrease its inhibition effect on tomato growth.
