Description
Technical Field
The invention relates to the technical field of agricultural water bamboo planting, in particular to a method for preventing abnormal growth of water bamboo seedlings.
Background
The double-cropping water bamboos are main cultivation types in each water bamboos production area in China, the water bamboos are harvested twice in one year, the water bamboos are harvested in the first half year, the water bamboos are harvested in the second half year, the water bamboos are harvested earlier to the market, the price is higher, so that the double-cropping water bamboos are planted in places such as Huangjiang river cities and Fujian Zhang cities and the like by utilizing the advantage of quick temperature return in early spring, the water bamboos are promoted to the market early to obtain better benefits, for example, the double-cropping water bamboos are planted in open field in 4 months and harvested, the Fujian Zhang cities are lower in one latitude, the temperature return in early spring is quicker, the water bamboos are planted in open field in 3 months and harvested in greenhouse cultivation in 3 months. The temperature of the double-season water bamboo suitable for pregnant water bamboo is 15-25 ℃, the highest temperature of the Zhangzhou city is about 20 ℃ in 2 months, the temperature requirement of the pregnant water bamboo is met, water bamboo farmers in the Zhangzhou city can harvest and sell water in the late days of 2 months in advance, field planting of water bamboo seedlings is tried to be carried out from the middle ten days of 1 month to the upper ten days and the middle ten days of 12 months in advance, but 20-30 days after field planting of the seedlings, when the plant is extracted to the height of 30-40 cm, the phenomenon of plant growth stagnation (hereinafter called stiff seedlings) occurs, and the obtained water bamboo is small in size, abnormal in shape and free of commodity property until the late days of 2 months, so that the plant starts to be pregnant with the water bamboo. If the planting time is earlier than the other, the marketing time of the water bamboo is overlapped with the marketing time of the autumn water bamboo in double seasons, and the water bamboo does not have price advantage. If the planting time is delayed, the harvesting time is also delayed, and the wild rice shoots cannot be harvested in the last ten days of 2 months.
In order to avoid the phenomenon of stiff seedlings, some water bamboo farmers adopt a method of planting after hardening seedlings, divide selected seed piers into small piers, bake the seed piers by sun or open fire (called hardening seedlings), carefully control the fire in the process so as not to wither the seed piers, then plant the seed piers in a seedling bed at the end of 10 months to 11 months, and plant the water bamboo in a field in the middle of 12 months. The method can reduce the seedling hardening phenomenon, but has the defects of complex process, difficult mastering of the duration and duration of hardening off, and frequent occurrence of seedling hardening off failure.
Disclosure of Invention
The invention aims to solve the problems in the prior art, provides a method for preventing abnormal growth of cane shoots, and solves the problem that stiff seedlings occur in the existing cane shoots.
The invention adopts the technical scheme for solving the technical problems that: the method for preventing abnormal growth of the zizania latifolia seedlings comprises the following steps:
firstly, preparing seed piers, cutting the selected seed piers into a plurality of small seed piers, wherein each small seed pier contains 2-3 old bolting pipes;
secondly, field planting of wild rice shoots, wherein field planting is carried out according to a wide-row and narrow-row mode in the middle ten days of 12 months, the row spacing of wide rows is 1.2m, the row spacing of narrow rows is 0.7m, the plant spacing is 0.5m, and 1 small seed pier is planted in each hole;
thirdly, building an arched shed, namely building the arched shed by using bamboo materials in the wide field, planting 2 rows of water bamboo in the shed, wherein the shed shoulder height is not less than 50 cm, and the shed top height is not less than 90 cm;
fourthly, managing the arched sheds, namely covering shed films immediately after the arched sheds are built, and mainly sealing the shed in sunny days during the film covering period of the arched sheds, so that the temperature in the shed is raised and kept between 30 ℃ and 38 ℃ for a long time, but when the temperature in the shed is raised to be higher than 38 ℃ in particularly high-temperature days, ventilating and properly cooling the two sides of the arched sheds to keep the temperature in the shed between 30 ℃ and 38 ℃;
and fifthly, removing the film, and managing the arched shed film covering for 30 days, wherein the plant height is more than 60 cm in 1 month mid-ten days, namely removing the shed film, and performing subsequent management according to the local open-field double-season water bamboo management mode.
Further, the long time in the fourth step ranges from 7 hours to 9 hours per day.
The principle of the invention is as follows: the method for preventing the abnormal growth of the zizania latifolia seedlings is characterized in that the temperature in the arched shed is increased to more than 30 ℃ to exceed the proper temperature range for the propagation of the zizania latifolia schneid, the breeding temperature of the zizania latifolia schneid is 15-25 ℃, namely the suitable temperature of the zizania latifolia schneid in the south low latitude area of China, even in the period from 12 months to 1 month in winter, the highest temperature in the daytime is usually more than 19 ℃, the zizania latifolia schneid breeding is very suitable, the content of the zizania latifolia schneid in the seedlings is at a higher level, the breeding growth of the zizania latifolia schneid needs to absorb the nutrition in the plants, the nutrition competition with the growth of the plants is formed, the nutrition competition is weak in the seedling stage of the plants, the phenomena of plant growth stagnation and seedling are easy to occur, the abnormal growth of the zizania latifolia schneid seedlings can be prevented by utilizing the arched shed to increase the temperature in the shed to more, the nutrient competition capability is reduced, the growth of plants is facilitated, and the phenomenon of seedling stiffness is avoided. When the plants are in the seedling stage and the nutrition competition capability is enhanced, the arched shed can be removed, and the seedling phenomenon can not occur.
The method has the advantages that the adopted arched shed is small, the material cost is low, the arched shed management time is short, only 1 month is needed, the management cost is low, the harvesting time of the wild rice shoots can be advanced to 2 months middle and late, the harvesting time of the wild rice shoots is later instead due to high temperature in the shed and other reasons when the wild rice shoots are cultivated in the conventional greenhouse locally, the wild rice shoots are harvested in 3 months middle and late, the greenhouse material cost is high, the management time is long, and the management cost is correspondingly increased.
The invention has the beneficial effects that: according to the method for preventing the abnormal growth of the wild rice shoots, the phenomenon of stiff seedlings after field planting of the summer wild rice shoots is solved by building an arched shed film covering and temperature increasing mode in the seedling stage of the field double-cropping wild rice shoots, so that the wild rice shoots can be harvested in the last ten days of 2 months, the planting benefit is increased, the market supply is enriched, the technical effect is good, and the popularization is facilitated.
