A new and distinct cultivar of Sansevieria plant named ‘HANSOTI59’ is disclosed, characterized by foliage variegation in the form of linear bands and streaks of different grey-greens and creams along the length of the leaf, a dark green leaf border and a golden yellow suffusion towards the base of the leaf. Unusually upright, relatively narrow leaves give a particularly vertically oriented narrow rosette of greyish-green to cream-streaked leaves. Unique slow changing of the variegation pattern and color of new leaves as more leaves emerge from an older plant to give a creamier look as the plant ages. The new cultivar can be classified in the Compact Sansevieria Group. The new variety is a Sansevieria, typically produced as an ornamental plant.

This invention discloses a highly efficient irrigation method for promoting grain filling by regulating the chlorosis trait in rice. This method involves shallow-water-drying quantitative irrigation, where water is naturally allowed to dry from a shallow water layer to a specified soil water potential before being re-irrigated to a shallow water layer, and this cycle is repeated. First, the presence of chlorosis in rice plants is determined based on a leaf color threshold. Then, for varieties exhibiting chlorosis, the degree of soil drying at each growth stage is quantitatively determined based on the panicle type of different rice subspecies and leaf age patterns. This method, by controlling field water potential, creates mild water stress on the plants, thereby regulating plant senescence (i.e., chlorosis trait). It also enhances the activity of key enzymes in sucrose-starch metabolism in the stem sheath and grains, thus promoting the translocation of assimilates from the stem sheath to the grains, increasing grain filling rate, and achieving yield increase.
