Method for accelerating seedling formation of second-crop zizania latifolia of zizania latifolia

Abstract

The invention provides a method for accelerating seedling formation of second-crop zizania latifolia of zizania latifolia. The method comprises the following steps of stripping epiphytic leaves on septate internodes where germinated axillary buds are located from the last ten days of May when the germination length of the epiphytic axillary buds on septate internodes at the base parts of zizania latifolia stems is more than or equal to 3cm from the zizania aquatica pregnancy period to the zizania latifolia harvesting end period of first-crop zizania latifolia; when the zizania latifolia pregnancy rate of the first-crop zizania latifolia plants reaches 50%, zizania latifolia pregnancy fertilizer is applied; the zizania latifolia is harvested when 0.5 cm to 1 cm of the zizania latifolia is exposed out of one side of the fleshy stems of the first-crop zizania latifolia, the fleshy stems and the four leaves wrapping the fleshy stems are picked off together during harvesting, and other leaves remain on the zizania latifolia stems; after the whole-field zizania latifolia is harvested, a high-nitrogen compound fertilizer is applied; and 10-15 days after harvesting of the whole-field zizania latifolia, residual plants and leaves left on zizania latifolia stems are removed in cloudy days. According to the method, the second-crop zizania latifolia is grown in advance, grown seedlings areaccelerated, the growing number is increased, the yield of the second-crop zizania latifolia is increased through leaf stripping from the zizania latifolia pregnancy period to the zizania latifolia harvesting end period, delayed leaf cutting after zizania latifolia harvesting end and cooperation with timely application of the fertilizer, a new yield increase scheme is provided for the second-cropzizania latifolia, and the effect is obvious.

Description

technical field [0001] The invention belongs to the field of Zizania planting technology, and in particular relates to a method for accelerating seedling growth of Zizania regenerated from Zizania. Background technique [0002] The planting mode of single-season watermelon with two harvests per year is to change the single-season watermelon variety from once a year to two crops a year through measures such as planting in advance, fertilizer and water management, micro-fertilizer and growth agent adjustment. The harvesting time is from early June to early July, and the harvesting time of the second crop of Zizania zizania (also known as regenerated water bamboo) is from mid-September to early October. Due to the high yield of this model, the harvesting time of zizania is staggered from that of other planting models. The advantage of staggered peak listing, so the planting benefits are good. This model has been widely promoted in Lishui City, Zhejiang Province, and gradually r...

Problems solved by technology

[0005] The replanting method needs to reserve another field for the planting of replanted seedlings, and the process is relatively cumbersome

Using the harvesting method of high shoot tube and leaving leaves, it is necessary to spray enhanced concentrated ammonia-calcium rare earth king according to the growth of the field plants. The timing of spraying is difficult to grasp, and sometimes the seedling rate of regenerated watermelon does not reach the expected effect.
