Wheat seed is a fruit, which is mainly composed of seed coat, endosperm and embryo. The seed coat has a protective effect, while the endosperm can store nutrients, and the endosperm is often processed into wheat flour. When storing wheat, it should be exposed to the sun before storage, because wheat has strong hygroscopicity. If the moisture content is higher than 12.5%, it will be damaged, and moisture-proof measures should be taken after storage.
1. What seeds do wheat seeds belong to?
1, what is the wheat seed?
Wheat seeds are fruits, and wheat consists of seed coat, endosperm and embryo. The seed coat has a protective effect, and the embryo includes radicle, embryo, hypocotyl and 1 lobule. The endosperm is mainly used to store nutrients, and the wheat flour that is often eaten is processed from the endosperm.
2, the method of storing wheat
(1) Strictly control moisture: Wheat has strong hygroscopicity, so it should be exposed to the sun after harvest. After the moisture is controlled below 12.5%, it should be put into storage and moisture-proof measures should be taken.
(2) Low-temperature sealed storage: Long-term exposure to high temperature will affect the quality of wheat. After the weather turns cold in autumn, mechanical ventilation can be used to fully dissipate heat, and before the spring is warm, the cover should be sealed to keep the wheat seeds in a low temperature state.
Second, what does it mean that seeds are highly susceptible to scab?
1, the meaning of highly susceptible scab
The high sensitivity of seeds to scab means that the seeds are very likely to be infected with scab during their growth. The disease mainly causes seedling blight, ear rot, stem base rot and stalk rot, which can be harmed from seedlings to heading. Therefore, during the planting process, prevention and control work should be done to ensure the normal growth of crops.
2. Methods of preventing and controlling seed diseases
(1) seed soaking method
4kg of 40% carbendazim colloidal suspension was mixed with 500kg of water to prepare a 0.4% liquid medicine. Cotton seeds were soaked in 200kg for about 10- 15 hours, stirred for 1-2 times during soaking, and then taken out and drained, and now planted or dried in the sun for reserve seeds, which can prevent cotton withering and drying.
(2) Seed dressing method
Adding 50% phoxim or 50% monocrotophos EC 1500-2000g of water and mixing 50kg of wheat seeds can control underground pests such as crickets, and the drug effect usually lasts for about 30 days.
(3) seed-closing method
Add 200g of 25% carbendazim and 250g of 50% monocrotophos into 1.5-2.5kg of water, mix them evenly, spray 50kg of wheat seeds, and then bury them for 6 hours to sow, which can prevent diseases and kill insects.
1. Culture medium: Termitomyces nigricans is saprophytic and suitable for growth in a slightly acidic or neutral environment. When planting black
