“…Compared with the traditional way of seedling raising, the factory seedling has the advantages of scientific environment control, automatic irrigation, uniform growth and high quality of seedling [18] , which could improve the production efficiency and reduce the adverse effects of objective factors such as weather. Thus, it is widely used in the seedling production of vegetables.…”

High-quality cucumber seedlings are a prerequisite for ensuring high yield of cucumbers. With the continuous increase of cucumber planting area in China, the demand for high-quality cucumber seedlings is also increasing. One of the important ways to improve the quality of cucumber seedlings is to improve the light environment by using artificial light source. In this study, three cucumber seedlings (cv. Jintong, cv. Yunv and cv. Xiazhiguang) were grown for 23 d under eight levels of daily light integral (DLI) at 4.3 mol/(m 2 • d), 8.6 mol/(m 2 • d), 10.1 mol/(m 2 • d), 13.0 mol/(m 2 • d), 5.8 mol/(m 2 • d), 11.5 mol/(m 2 • d), 14.4 mol/(m 2 • d) and 17.3 mol/(m 2 • d), respectively. The results showed that when DLI was 14.4 mol/(m 2 • d), the seedling height, stem diameter, total leaf area and shoot dry/fresh weight of all three cucumber cultivars reached the maximum, while hypocotyl length decreased with the increase of light intensity. When DLI was 14.4 mol/(m 2 • d), Jintong and Xiazhiguang had the highest health index, which were 49.29 and 28.56, respectively, while that of Yunv was 81.59 (DLI = 14.4 mol/(m 2 • d)). With the increase of DLI, the photosynthetic capacity of cucumber increases gradually. The highest net photosynthetic rate was shown at DLI of 14.4 mol/(m 2 • d), while the chlorophyll content of cucumber seedlings of all three cultivars were less affected by DLI. Jintong and Yunv had the highest chlorophyll content when DLI was 8.6 mol/(m 2 • d) because they were adapted to low-light environment. In conclusion, the DLI of 14.4 mol/(m 2 • d) for Jintong and Xiazhiguang, while that of 17.3 mol/(m 2 • d) for Yunv are suggested for the light environment design of factory-cultivated seedling for cucumber.

“…At the same time, if sowing too late, the safe full-heading stage of the ratooning season will be affected by low temperatures [23]. In actual production, producers have adopted various means to achieve seedling raising in advance, such as plastic film seedling raising [26], greenhouse seedling raising, and factory seedling raising [27]. In conclusion, according to the conditions of temperature and light resources in the planting area, the selection of ratoon rice varieties with a moderate growth period and sowing as early as possible is conducive to the growth of the reproducing season and increases yield (Figure 3).…”

In this review, the significance of ratoon rice was introduced, and the research status and development trends of ratoon rice were also summarized. It is pointed out that mechanically harvested ratoon rice is the developing direction of future ratoon rice. On this basis, we analyzed the relationship between the yield of ratoon rice and many factors, such as variety characteristics, sowing date, water control, fertilizer, and many others. It is important to construct a comprehensive and practical evaluation system for rice regeneration that can provide a basis for high-yield cultivation of machine-harvested ratoon rice. At the same time, it is suggested that combining high-yield cultivation with the green ecological efficiency of rice can achieve better production and improve the quality of rice. Finally, some problems with ratoon rice development were put forward. An in-depth study on the rhizosphere biology and regulation techniques of ratoon rice and the effective ecological compensation mechanism increased the capacity and quality of ratoon rice. Further, the functioning of such research can enhance the planting area for ratoon rice and improve food security.

Understanding the effect of climate warming and technological progress on crop production systems is crucial for developing climate adaptation strategies. This study presents a methodological framework with which to assess the suitability of the double rice cropping system in Southern China and the effects of crop management and climate warming on its distribution. The results indicate that the isolated effects of climate warming have led to the northward and westward expansions of double rice northern limits over the past six decades and an increase in suitable areas by 4.76 Mha. Under the isolated effect of crop management, the northern limits of the medium- and late-maturity double rice changed significantly due to the increased accumulated temperature required caused by varietal replacement and planting date change, which moved an average of 123 and 134 km southward, respectively. A combined scenario analysis indicated that crop management could offset the effects of climate warming and push the northern limits southward, reducing the overall suitable area by 1.31 Mha. Varietal replacement and other crop management methods should also be appropriately considered in addition to climate warming to develop locally adapted agricultural management strategies.
