The leafhopper dish, Patamogeton natans L. is an ophthalmology branch of the eye, perennial herb, floating in the surface of
Rice fields, root-like stolons. There are two forms of leaves, one is the submerged sheet, which is petiole-like; the other is floating leaves, with long handles, the leaves are oval-shaped moment to oval, full. Stipules lanceolate, spikes axillary at stem, nutlets obovoid, ridged at back, and short beak at top. It is mainly distributed in the old paddy fields and low-lying wetlands. It is severely connected and competes strongly with rice for water and nutrients. Therefore, the floating leaf is a vicious weed in rice fields. Over the past years, the floating leaf eye dish does not constitute the dominant population of weeds in rice fields, but it is only occasionally fatal. However, in recent years, rice fields in the Qingjian River Basin have been increasing year by year. Even in low-lying rice fields, some of the land has risen to dominant species, causing huge losses to rice farmers. Therefore, we should attach great importance to the floating leaf eye dishes, must not be taken lightly, allowing it to continue to develop. According to data reported that under conditions that do not control, can reduce rice production by more than 50%, and even serious enough to reach the extent of no. First, the control period: In addition to eradication of weeds in paddy fields is very important. Too early to achieve the desired effect; too late, not only can not kill weeds, but also cause phytotoxicity to rice. According to our observations, the best time to control floating leaf eye dishes is to select one month after rice transplanting, when the rice enters the tillering stage but the rice leaves have not been ridged, the leaves of the floating leaf eyed vegetables unfold and turn from red to green. At that time, it was the critical period for the treatment of the eyelids. Second, the prevention and control methods: Floating leaf eye dishes, is the eye of the vegetable, perennial herbs, in addition to a lot of chemical agents, but the use of production effects are uneven. Several methods are introduced for reference. 1. Apply 5.3% Dingxi Granules 1.5 to 2.0Kg for every 666.7m2. When using drugs, pay close attention to weather changes. If the temperature exceeds 28°C, it is easy to produce phytotoxicity, so it should be used with caution. 2. Use 66.7% of total 666.7m2 with 61.7% of Wuliangpeng granules (300-450g) to mix with 20-30kg of evenly applied soil. 3, every 666.7m2 with 25% Western grass net wettable powder 100 - 200 grams mixed wet sieve soil 20 - 30Kg, after spraying the soil to maintain 3 - 5cm water layer 5 - 7 days. Better control. 4, every 666.7m2 with 50% paracetamol WP 65 - 100 grams of mixed wet sieve soil 20 - 30Kg, uniform application. Keep 3 - 5cm water layer 7 - 10 days, the control effect will be better. 5, every 666.7m2 with 50% paracetamol WP 40 - 50 grams, plus 20% 2 A 4 chlorine water agent 30ml, mixed wet sieve soil 20 - 30Kg, uniform application. Keep 3 - 5cm water layer 7 - 10 days.
Rice is a
finished product made after the process of rice cleaning, glutinous
rice, rice milling, and finished product finishing. The
embryo and aleurone layer of rice contain nearly 64% of rice nutrients
and more than 90% of the nutrients required by the human body. It is the
main food of the people of the South.
The carbohydrate in rice is mainly starch, and the edible rice has higher nutritional value.
Storage taboo
Rice
should not be stored at the same time as foods with high moisture such
as fish, meat, vegetables, etc., otherwise it will easily cause water to
cause mildew; rice should not be stored directly on the ground, and
should be placed on a dry, ventilated and clean pad; indoors should be
stored with high moisture content. Otherwise, it
is easy to absorb water and cause mildew; the family avoids rice stored
in the kitchen because the kitchen has high temperature and high
humidity, which has a great influence on the quality of rice.
