Lolium temulentum L. Commonly known as wild wheat, is a Gramineae. Long-cherry venom Lolium temulentum var. Zlongiaristatum Parnell. Hotan temulentum var. arvense Bab. Two variants. It is a toxic weed that grows in wheat fields. Distributed in the Northeast, North China, East China, Northwest and other places. Poisonous wheat has strong stubbornness, which affects the growth of wheat and reduces yield and quality. What is more serious is that the poisonous wheat contains toxic alkaloids (C7H1 2N2O), which can paralyze the central nervous system of animals. People who eat flour containing 4% toxic wheat produce dizziness, coma, nausea, vomiting and convulsions. Horses, pigs, and chickens that have eaten toxic foods for 7 kun will poison and faint.
Morphological characteristics Poison wheat is a grass weed. The base of the seedlings is purplish red, and then becomes green. The adult stems are smooth and hard. The leaves are narrow and thin, the backs of the leaves are smooth, the leaves are rough, and the veins are obvious. It is higher than wheat dwarf or higher than wheat, spike-shaped flat long, wavy bending, with 8-19 spikelets per spike, 2-6 seeds per spikelet, alternately on the rachis, and the seeds on the spikelets are arranged into 2 In addition to the spikelets in the top two spikelets, the spikelets were missing in the first spike, the second spike was large and narrow, and the length was similar to the spikelets. The grain is tightly packed inside and outside, and is not easily detached. The raspberry segment is visible on its ventral surface. The grain is long and oval, and the abdomen is wide, hard, dull and grayish brown.
The ecological characteristics are transmitted through the transport of mixed wheat varieties with toxic wheat seeds. Mature grains are easy to fall off in the field. Poisonous wheat is multiplied by seeds and has many seeds. Its fertility is 2-3 times larger than that of wheat. It still has germination power in indoor storage for 2 years and can still be excavated in the depth of 10 cm.
Prevention and control methods (1) Strictly implement the quarantine system. After the head wheat has been headed and raised, field investigations are conducted and quarantine inspections are conducted. (2) Selection and establishment of non-toxic wheat-remaining farms Selection of seeds with 50% ammonium sulfate water or 60% ammonium nitrate water (solution specific gravity of 1.192 and 1.180, respectively). The results are good and stable and can be removed. More than 90% of the poisonous wheat in the wheat species must be washed with water immediately after selection so as not to affect the seed germination. The use of Su-type universal seeder and hand-operated tube seeder has a good effect on the elimination of poisonous wheat. Based on the selection of the species, a non-toxic wheat land was selected to establish a seed-retaining field, and the poisonous wheat plants were strictly extracted to obtain a completely non-toxic wheat seed. (3) Tillage control Fall ploughing is performed in the spring wheat area to expose poisonous wheat out of the soil, germinate in the same year, and freeze to death in winter. (4) Before the wheat is harvested, pull out the poisonous wheat so as not to mix in the wheat seed or fall into the soil.
Everyone knows that there are a few longevity villages in China, and I live in one of them. I have lived here for 22 years, where chrysanthemums are everywhere and fragrant. Every morning, Grandma would make a pot of chrysanthemum tea and do other things after drinking. Grandma said, "Chrysanthemum can be used as medicine to cure diseases, chrysanthemum tea can make people live longer, chrysanthemum can also be made into exquisite delicacies." Grandma often cooks a dish called "chrysanthemum meat", "chrysanthemum meat" is a kind of chrysanthemum which has been made through long-term exploration. It is made from a piece of white tender pork processed by boiling sucrose pulp. It*s exquisite and exquisite, like white jade. Each piece is covered with a few chrysanthemum petals, which are full of fat, sugar and sweetness. The golden color is observed. The meat in the mouth is vegetable, and the meat in the vegetable is sweet and not greasy. It is really a famous dish. Grandma said that her ancestors did so. Slowly, everyone used it, and the village gradually became a longevity village.
