Quarterly Zizania aquatica two-harvesting-in-one-year mode second crop yield increasing method

Abstract

Disclosed is a quarterly Zizania aquatica two-harvesting-in-one-year mode second crop yield increasing method. Tillering plants in the reserved field are transplanted to unborn Zizania aquatica piers in the yield increasing field, and the unborn Zizania aquatica piers in the yield increasing field can be born again. The method has the advantages that the problem that quarterly Zizania aquatica two-harvesting-in-one-year mode second crops are low in yield is solved, on the basis of keeping harvesting time consistent, the yield of the quarterly Zizania aquatica two-harvesting-in-one-year mode second crops is equal to that of quarterly Zizania aquatica two-harvesting-in-one-year mode first crops, the yield of the Zizania aquatic in the quarterly two-harvesting-in-one-year mode is improved, the operation is easy and convenient, investment is low, cost is low, a Zizania aquatica farmer can easily grasp the method, the use effect is good, and popularization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, in particular to a method for increasing the production of the second crop in the mode of two harvests a year of single-season wild rice stems. Background technique [0002] The traditional single-season Zizania planting technology can only harvest one season of Zizania a year, with low yield and poor production efficiency. [0003] The single-season Zizania harvest model is a planting model used in Zhejiang to increase the yield of single-season Zizania. This planting model uses measures such as planting in advance, micro-fertilization, and growth agent adjustments to make single-season Zizania harvest. The time is advanced from early September in the traditional planting mode to mid-June to early July. After harvesting the wild rice stems, there is no need to replant them. Through conventional management, the second batch of wild wild rice stems will be harvested from late September ...

Problems solved by technology

[0005] However, there is still the problem of low output of the second harvest in the single-season and double-harvest mode. The second harvest in the single-season and double-harvest mode is the re-pumping of the original rice stem after the first crop is harvested. , the number of re-extracted wild rice stems determines the yield of the second crop of wild rice stems, the uniformity of harvesting of the first crop of wild rice stems, the damage of diseases and insect pests, and the fact that muddy water is easily brought into the section of the plants during harvesting of the first crop of wild rice stems. Pile rot is the factor that affects whether the second crop can be re-pumped. In actual production, the number of pier that can be re-pumped is generally only 50% to 60%. Therefore, the output of the second crop is lower than that of the first crop. In order to increase the yield of the second crop of wild rice stems, the farmers generally adopt the following method in production: divide the bamboo shoots that can be re-pumped, and replant them on the non-re-pumped water. This method is limited by the number of fresh bamboo shoots, the yield is not significantly increased, and the harvest time of the second crop of wild rice stems is obviously delayed, not only the yield is not improved obviously, but also the economic benefits are affected, and the effect is poor
