Abstract
The invention discloses a cultivation technology for promoting stem swelling of wild rice stems. The cultivation technology comprises the steps of growing seedlings and planting the seedlings in a field, wherein tiller stems on the lower portion of wild rice stem rods producing wild rice stems laser year are planted in a wild rice stem field in a cuttage mode from October to November, or tiller seedlings in an old wild rice stem field are transplanted into the wild rice stem field from early March to the early April; conducting conventional management of the wild rice stem field. The cultivation technology is characterized in that when wild rice stem seedlings grow to the later stage of tillering and the initial stage of jointing and the effective numbers of wild rice stems per mu reaches a target number, deep water irrigation of the wild rice stem field is conducted; meanwhile, under the light condition, underground water with temperature lower than 20 DEG C or water of a shady and cool spring is sprayed to wild rice stem plants with stems about to swell through spraying facilities so that the temperature of the wild rice stem plants can be lowered, an appropriate-temperature condition of stem swelling is created, and stem swelling of the wild rice stem seedlings is promoted. According to the cultivation technology, due to the fact that manual intervention in the growth environment of wild rice stems is conducted during stem swelling of wild rice stems, stem swelling of wild rice stems can be promoted under the condition of different altitudes, the quality of wild rice stems can be greatly improved, and the production benefits of wild rice stems are increased.
Description
Technical field
The present invention relates to a kind of culture technique of wild rice stem, refer more particularly to the pregnant hay control technique of single cropping hay, belong to crop genetics field.
Background technology
Wild rice stem is the important aquatic vegetable of China, according to the requirement of counterglow length, is divided into two season hay and two kinds of cultivated forms of single cropping hay, in the Yangtze river basin and areas to the south plant in a large number.Because the pregnant hay of wild rice stem will reach two conditions, the one, wild rice stem plant will have certain nutrient accumulation, and namely wild rice stem plant is wanted certain amount of growth, breeding time; The 2nd, smut is infected wild rice stem plant, and cripetura stem stress cause lopsided the expanding of several joints of front end and form edible wild rice stem position.
The suitable growth temperature of ustilago esculenta is 15～28 ℃, and in the time of 32 ℃, its growth is subject to severe inhibition.Therefore, in the conventional cultivation of wild rice stem, after wild rice stem plant reaches certain amount of growth, utilize the preference temperature of spring and autumn, smut is infected to wild rice stem stem apex, form edible wild rice stem.In production, two season plantations are generally planted in flat area, in field planting in July, gather in the crops then wild rice stem in 10-November and 4-June of next year, and a kind of two receive.Single cropping hay is as pregnant hay after planting after needing September flat area temperature and declining, and along with planting area height above sea level increases, thereby temperature declines thereupon, can suitably do sth. in advance pregnant hay.On market, be that fresh wild rice stem goes on the market minimum season mid-August, and economic benefit is best, therefore, utilizes at the mountain area of certain height above sea level plantation single cropping hay and realize the listing of neutral gear phase in production.Actual from Zhejiang Province's production, in the cultivation of conventional mountain area, height above sea level 800 m region single cropping hay Time To Markets accord with the demands of the market most.But due to 800 m height above sea level mountain region resource-constraineds, even also Climate variability for a certain reason of this ecological region planting, the cultivation management technology of existing routine, is difficult to ensure in good time pregnant hay and the wild rice stem quality of producing.
Summary of the invention
The technological deficiency existing for existing culture technique, the present invention proposes the external environment condition that the pregnant hay of wild rice stem is controlled in a kind of artificial creation, ensures that single cropping wild rice stem plant is reaching under the prerequisite of nutrient accumulation, realizes wild rice stem in the culture technique scheme of pregnant hay mid-August.
The present invention realizes by following manner: a kind of culture technique that promotes the pregnant hay of wild rice stem: comprise the field planting of growing seedlings, get and tie part under the hay bar that hay crosses last year and be referred to as tongue pipe, in cuttage in 10-November to hay field, or the tillered nursery plant of getting old hay field to early April at early March is transplanted to hay field, and the process to hay field enforcement Routine Management, it is characterized in that: at hay seedling, grow to late tillering state to the jointing initial stage, when every mu of effective hay seedling amount reaches destination number, Deep irrigation is implemented in hay field; Under illumination condition, water intaking temperature, lower than 20 ℃ of underground water or shady and cool mountain spring water, utilizes spray facility to carry out spray cooling to being about to the wild rice stem plant body of pregnant hay, creates the thermophilic condition of a pregnant hay of wild rice stem, promotes the pregnant hay of hay seedling simultaneously.
Because the present invention is by the pregnant hay process of wild rice stem, carries out the manual intervention of wild rice stem growing environment, thereby promoted the pregnant hay of wild rice stem, make under different altitude height condition, all can promote the pregnant hay of wild rice stem, and can make the quality of wild rice stem be greatly improved, improve the productivity effect of wild rice stem.
