Technical Field

The invention belongs to the technical field of agricultural production, and particularly relates to a method for promoting early pregnancy of cane shoots by triacontanol and a new application of triacontanol.

Background

Cane shoots (Zizanialatifolia) The zizania perennial root herbaceous plant belongs to gramineae, is an important aquatic vegetable originally produced in China, is widely cultivated in Yangtze river watersheds and southern areas, is the second most aquatic vegetable in China except lotus roots at present, has a planting area of more than 50 mu and more than ten thousand mu only in Zhejiang province, and has important economic value. The Zizania latifolia cultivars can be classified into different types according to photosensitivity, maturation time, harvesting time, planting geographical difference, cultivation mode, smut infection and the like. Wherein the water bamboo is divided into single-cropping water bamboo and double-cropping water bamboo according to the photosensitivity and the harvesting time. The single-cropping water bamboo is planted in spring, the water bamboo is harvested once in autumn every year, the double-cropping water bamboo is generally harvested in autumn of the planting current year (autumn water bamboo), and the single-cropping water bamboo is harvested in summer of the second year (summer water bamboo).

Pregnant zizania aquatica and its endophytic fungus Ustilago esculenta (Ustilagoesculenta) The infections of (A) are closely related to each other. After the zizania latifolia is successfully infected by the zizania latifolia, the zizania latifolia flowers are inhibited, and the stems of the zizania latifolia are stimulated to expand to form edible expanded stems. The growth and metabolism of Ustilago esculenta are easily affected by external factors (such as temperature, exogenous substances, etc.). Therefore, the water bamboo bearing time of the water bamboo can be adjusted by using external factors, such as facility cultivation, mulching film covering, reservoir cold water irrigation, planting in different altitude areas, and adjusting the pregnant water bamboo period and harvesting time of the water bamboo by using exogenous substances such as herbicide (such as methoxone sodium, extremely prolific and extremely cyanine, bactericide sodium diquat and the like).

Triacontanol is a natural long carbon chain plant growth regulator, has a chemical name of n-triacontanol, is also called melissol, and is a natural biological product purified and extracted from bee wax. Has good yield increasing effect on rice, cotton, wheat, soybean, tobacco, flowers, fruit trees and the like, has no harm to human and livestock, has no side effect, and has no pollution to the environment. Triacontanol can be absorbed by stem and leaf of plant, and has effects of promoting mineral element absorption, promoting cell division, increasing chlorophyll content, promoting rooting and leaf growth, and flower bud differentiation, and increasing tillering.

Disclosure of Invention

In view of the problems in the prior art, the invention aims to design and provide a method for promoting the early pregnancy of zizania latifolia by using triacontanol and a new application of triacontanol. The method can promote the double-cropping water bamboo to improve the early pregnancy of the water bamboo, and the commodity of the obtained water bamboo is not different from that of the conventional water bamboo.

In order to achieve the purpose, the following technical scheme is adopted:

a method for promoting early pregnancy of cane shoots by triacontanol is characterized in that triacontanol solution is uniformly sprayed on leaves and leaf sheaths of cane shoots growing to the middle tillering stage.

The method for promoting the early pregnancy of the wild rice shoots by the triacontanol is characterized in that the concentration of the triacontanol solution is 0.5-4 mg/L.

The method for promoting the early pregnancy of the wild rice shoots by the triacontanol is characterized in that the concentration of the triacontanol solution is 0.5 mg/L.

The method for promoting the early pregnancy of the zizania latifolia by the triacontanol is characterized in that spraying treatment of the triacontanol solution is repeated twice, and the interval between the two treatment is 8-15 days.

Application of triacontanol in promoting early pregnancy of zizania latifolia.

The invention has the beneficial effects that a method for promoting the early pregnancy of the zizania latifolia by adopting triacontanol is not seen in the prior art, the invention discloses the application of the triacontanol in the early pregnancy of the zizania latifolia in field, provides theoretical basis and technical support for the mechanism and field production of the early pregnancy of the zizania latifolia, and can promote the early pregnancy of the zizania latifolia by adopting the triacontanol with proper concentration of 0.5 mg/L, wherein the whole harvesting period of the zizania latifolia is advanced, the total yield is slightly increased, the influence of the early harvesting period of the autumn zizania latifolia is large, the harvesting period is advanced, and the commodity of the obtained zizania latifolia is not different from that of the conventional zizania latifolia.
