Zizania aquatica, also known as high melon, Zizania shoots, Zizania hands, water bamboo shoots, high shoots. It is a perennial rooted herbaceous plant of the genus Zizania of the family Gramineae. Zizania in Shandong Xintai white Zhuangzi is known as one of the three good, from ancient times to the present, more than growing in the Yangtze River lakes around the area, suitable for freshwater growth. So how do you grow wild rice? The following is my introduction to the planting conditions and planting methods of wild rice, I hope to help you.
Zizania planting conditions
1, soil: Zizania soil requirements are not high, but not suitable for continuous cultivation, deep tillage, rich in organic matter clay and clay loam soil is best. Zizania plants are tall, long growing period, large fertilizer needs, need fertile soil, more basal fertilizer, subdivided fertilizer.
2, humidity: wild rice throughout the growth period can not be cut off, but wild rice is a water crop, so the water layer and can not be too deep, the water level should be adjusted according to the different fertility stages of wild rice.
3, temperature: wild rice is warm, intolerant of cold and high temperature and drought, in 5 ℃ above the beginning of sprouting, the appropriate temperature is 10 ~ 20 ℃, tillering period appropriate temperature is 20 ~ 30 ℃. The suitable temperature for the pregnant water bamboo period is 15 to 25 ℃.
4, light: wild rice requires full sunlight, air circulation. Because of the plant is tall, the field is easy to depression, so it is necessary to carry out a reasonable dense planting, the late growth should be diligent in addition to the yellow leaves, old leaves to increase ventilation and light, is conducive to the production of tillers.
Zizania planting method
1, planting time: the southern region of double-season wild rice is generally planted before the end of November to April or June to August planting but can only be harvested in the fall wild rice, at the latest at the end of April or August planting is completed. Single-season wild rice is generally cultivated in the spring, in the fall short sunshine pregnant wild rice, harvested in August of the lunar calendar.
2, seed plant selection: the standard of good mother plant for that year, neatly shaped, pregnant water bamboo early, more water bamboo, water bamboo meat fat, water bamboo shape, good, low water bamboo parts and maturity of the same, no male water bamboo, gray water bamboo, no shells in the green, deformed water bamboo dun to stay in the seed.
3, wild rice field selection: wild rice shoots early and late with the soil, water depth, water temperature control, etc., the general paddy field elevation than the low elevation of the early shoots, the windy back of the mountain field early shoots than the wind of the low-lying field, the soil is shallow than the soil depth of the field early shoots.
4, fertilizer method: the southern region of double-season wild rice fertilizer should be early rather than late, in order to promote early seedling, early pregnancy water bamboo, combined with the water layer management, to promote the early effective tillers, control the late ineffective tillers, to promote the pregnancy water bamboo, to improve the yield and quality.
5, weed control: wild rice cultivation can achieve the purpose of plowing, loosening the soil, weed control, and can improve the soil temperature, accelerate the decomposition of fertilizers, general cultivation of 2 to 3 times, the first time in the beginning of the plant green, and then every 15 days for a time.
6, remove stray plants: wild rice in planting should pay attention to the removal of stray plants, male wild rice and gray wild rice can not bear wild rice, should be removed at any time to remove the empty space can be used to tiller more than normal wild rice pier on the seedling replacement.
7, plant finishing: wild rice plant finishing is generally in the spring wild rice harvest late start, according to plant growth, the old leaves stripped clear pull light, the requirement is to pull clear not to pull the injury, pull down the yellow leaves stepped into the field as fertilizer.
8, seedling thinning and seedling replenishment: the southern region planted double-season wild rice each pier tiller up to 15 or more should be thinned out, set aside too dense small tiller, each pier to stay in the effective tiller of 15 to 20 or so, thinning after wild rice pier press a piece of mud in the middle, so that the plant is evenly distributed, ventilation and light.
