Then wild rice planting techniques and time is how? The following one to understand.
Wild rice is a kind of aquatic vegetables, taste crisp, green health, deep consumer favorite, many people in rural areas will plant their own.
So wild rice planting techniques and time is how? The following one to understand.
1, planting time
Southern regions planting double-season wild rice in November to the end of April, or June to August, single-season wild rice is generally planted in the spring.
2, selecting seeds and seedlings
Try to choose late maturity, high yielding double-season varieties or listed early, high yielding single-season varieties, seedling selection, it is best to choose strong growth, disease-free, no male plant water bamboo dun can be, that is, with a knife to cut off the mud with mud of the small dun water bamboo roots as seedlings.
3, fertilization
Pick paddy fields or shallow ponds for planting, and then deep tilling and fertilization, general fertilizer can be used organic fertilizer or farmyard manure, try not to apply chemical fertilizer.
After fertilizer application, the soil will be turned over y, mixing the soil and fertilizer evenly, and then irrigated and harrowed.
4, planting method
Planting wild rice remember must pay attention to the depth, not particularly deep, not particularly shallow, generally to the old roots buried in the soil 10 centimeters, the old grave tube flush with the ground is appropriate.
Spacing between 55-60, an acre of land can be planted about 1200 plants.
5, fertilizer management
Fertilizer to take heavy, light, heavy fertilizer principle, 12 ~ 15 days after planting 5 ~ 25,000 kg of human dung urine or urea 220 ~ 300 kg (known as seedling lifting fertilizer), in order to promote the effective tillering; tillering full season to see seedling conditions fertilizer prevention of premature senescence, generally 450 ~ 1,500 kg of urea per hectare; before and after the pregnancy of wild rice around the middle of August, fertilizer volume It is desirable to promote the fleshy tender stem expansion, increase wild rice yields.
6, field management
Wild rice grows in the early stage, because of the low temperature, easy to appear weeds, in addition to the seedling is easy to appear after the dead seedling, so it is necessary to timely weed replenishment.
When the summer high temperature exceeds 35 ℃, we should carry out deep irrigation to reduce the temperature, and regularly change the water to prevent the soil from lack of oxygen caused by root rot.
The water level is too high, will make the Carex tube elongation, easy to collapse.
Entering the harvesting period and overwintering period, wild rice fields should maintain a shallow water layer of 3 to 5 centimeters or wet state.
7, harvest
When the roots of wild rice is thick and full, it can be ripe for picking, probably in May each year to start maturing, did not grow ripe wait until five to seven days to see once, there are suitable for harvesting wild rice on harvesting, be sure to pay attention to often look at the ripe wild rice in time to harvest, blackened on the old.
Wild rice has a strong adaptive capacity, can be rotated with rice, mats, lotus root, water chestnut mustard, Cigu, gorgonians, etc., but also with eels, loaches, crabs or other fish, etc. **** raw, in planting, can be mixed planting, to improve economic efficiency.
