Seed price and planting method of Zizania caduciflora

Zizania caduciflora is a common aquatic vegetable, also known as high melon, bamboo shoots, tall bamboo shoots and so on. it is a perennial root herb of Gramineae, which is divided into double-cropping Zizania latifolia and single-cropping Zizania latifolia (or divided into one-cropping Zizania latifolia and two-cropping Zizania latifolia). Generally, double-cropping Zizania latifolia (double-cropping Zizania latifolia) has high yield and good quality. let's take a look at the seed price and planting method of Zizania caduciflora.

How much is the Zizania caduciflora seed per jin?

Zizania latifolia can not be propagated by seeds, but usually propagated by ramet method. The price of each plant is generally about 2-4 yuan, but the price varies greatly due to the variety, quality and producing area of the plant. The seed quality of Zizania caduciflora directly affects the rate, yield and quality of Zizania caduciflora, but the difference in time, quantity and cultivation management level of smut fungus often leads to species degradation and the emergence of male and grey Zizania latifolia, so the species should be strictly selected every year.

Planting conditions of Zizania caduciflora

1. Soil: Zizania caduciflora does not require high soil quality, but it is not suitable for continuous cropping, and clay and clay loam with deep tillage layer and rich organic matter are the best. The plants of Zizania caduciflora are tall, have a long growth period, need a large amount of fertilizer, need fertile soil, apply more base fertilizer and topdressing in different times.

2. Humidity: the water of Zizania caduciflora can not be cut off during the whole growth period, but Zizania caduciflora is an effluent crop, so the water layer can not be too deep, and the water level should be adjusted according to different growth stages.

3. Temperature: Zizania caduciflora preferred temperature, could not tolerate cold, high temperature and drought, and began to sprout above 5 ℃. The suitable temperature was 10-20 ℃ and 20-30 ℃ at tillering stage. The optimum temperature of Zizania caduciflora during pregnancy is 15-25 ℃.

4. Lighting: Zizania caduciflora requires sufficient sunshine and good ventilation. Because the plant is tall and easy to be clouded in the field, it is necessary to carry out reasonable close planting, and the yellow leaves and old leaves should be removed frequently in the later growth stage to increase ventilation and light, which is beneficial to the production of tillers.

What are the varieties of Zizania caduciflora?

1. Zhejiang Zizania latifolia No. 2: Zhejiang Zizania latifolia No. 2 is a double-season medium-ripe variety of Zizania caduciflora, which is short and chubby in shape, smooth, white, delicate in texture, non-fiber and delicious.

Heat-resistant and fertilizer-resistant, the meat is white and the part of Zizania latifolia is high. The quality is good, with a yield of 1250-1500 kg per mu and harvested in Guangzhou from September to November.

5. Wuxi Yan Zizania latifolia: Wuxi Yan Zizania latifolia has exuberant tillers, late maturity, enlarged bamboo shoots, the best quality, high yield, many verrucous wrinkles on the surface of the stem, white color, 750 kilograms per mu in autumn and 1500 kilograms in summer.

Planting methods of Zizania caduciflora

1. Planting time: double-season Zizania caduciflora is generally planted before the end of November to April or from June to August, but it can only be harvested in autumn, and the planting will be completed by the end of April or August at the latest. Single-season Zizania caduciflora is generally cultivated in spring, pregnant in short days in autumn and harvested in the eighth month of the lunar calendar.

2. Seed and plant selection: the standard of excellent mother plant is that the plant shape is neat, the pregnancy is early, the Zizania latifolia is more, the flesh is hypertrophic, the Zizania caduciflora is good, the position of Zizania latifolia is low and mature, there is no male Zizania latifolia, Zizania latifolia, and there is no Zizania latifolia.

3. The selection of Zizania caduciflora field: the early or late bearing of Zizania caduciflora is related to the soil layer, the depth of water layer and the control of water temperature. in general, the high altitude paddy field is earlier than the low altitude field, the windward mountain back field is earlier than the low-lying field, and the shallow soil layer is deeper than the soil layer.

4. Topdressing methods: double-season Zizania caduciflora in southern China should be fertilized sooner rather than later, so as to promote early seedling development, early pregnancy, combined with water layer management, promote effective tillering in the early stage, control ineffective tillering in the later stage, promote pregnant Zizania latifolia and improve yield and quality.

5. Weeding in the field: Zizania caduciflora cultivation can achieve the purpose of ploughing, loosening the soil and weeding, and can increase the soil temperature and accelerate the decomposition of fertilizer. Generally, the field is carried out for 2 or 3 times, the first time when the plant begins to turn green, and then once every 15 days.

6. remove miscellaneous plants: when planting Zizania caduciflora, attention should be paid to removing miscellaneous plants. Male and grey Zizania latifolia can not bear fruit and should be removed at any time. The vacancy removed can be filled by seedlings on the normal tillering pier.

7. Plant arrangement: the plant arrangement of Zizania caduciflora generally begins in the late stage of spring harvest. According to the growth of the plant, the withered leaves are stripped clean and bare, and the pulled yellow leaves are required to be pulled out and stepped into the field as fertilizer.

8. Thinning seedlings and replenishing seedlings: double-season Zizania caduciflora planted in the south should be thinned when there are more than 15 tillers per stump, and the small overdense tillers should be removed, leaving about 15-20 effective tillers per pier. After thinning seedlings, a piece of mud is pressed in the middle of the pier, so that the plants are evenly distributed, ventilated and transparent.
