Rice seedling raising methods and key technical points for seedling-stage management
Seed treatment To improve the germination rate of rice, the seeds should be sun-dried before sowing, then 2 ml of Baike (25% prochloraz) or 15 g of Exianqing (16% prochloraz·cartap) is added to 5-6 kg of water to soak 5-6 kg of rice seed, and for every 5-6 kg of water, 10 g of 10% imidacloprid wettable powder is also added, soaking for 72 hours, soaking by day and airing by night, then accelerating...

How to prevent and control bacterial wilt and damping-off in rice seedlings at 10 days of raising seedlings?
For bacterial wilt and damping-off, prevention is more important than cure. Only when the rice seedlings are robust are they less likely to become infected, so field management should be strengthened. Pay attention to controlling the seedbed temperature; it should not be too high or too low. In particular, pay attention to the effect of the low temperatures of a late spring cold snap on the rice seedlings, and harden and root-restrict the seedlings at the appropriate time; the humidity during seedling raising should not be too high, as high humidity easily causes various diseases and...

Key points of tomato seedling raising technology, how to grow strong seedlings
How to raise tomato seedlings well? Please introduce and guide. Raising tomato seedlings by green branch cuttings is a seedling-raising method that uses side branches from mature tomato plants that have already flowered and fruited for asexual propagation. After nearly three years of practice, I have found three major benefits: first, it can save seed investment. Especially for expensive imported varieties...

How to prevent and control damping-off disease when raising rice seedlings
How to prevent and control damping-off disease when raising rice seedlings? Asking for guidance. Although dry-raised rice seedling beds are not prone to seedling rot, they are most susceptible to damping-off disease causing seedling death, with 20%-30% loss in mild cases and over 50% in severe cases. The following measures can effectively prevent and control damping-off disease. 1. Acid adjustment treatment of soil: For neutral and alkaline soil, before sowing...

Spring Asparagus Planting: Seedling Raising Methods and Key Technical Points
How do you raise seedlings for spring asparagus planting? Please advise. Asparagus production generally adopts seedling raising and transplanting. Centralized seedling raising and transplanting gives a high emergence rate, can save seeds, lower costs, facilitates centralized management, helps prevent and control pests and diseases and cultivate strong seedlings; it can extend the growing period in the planting year and increase the yield in the second year; when transplanting, the seedlings can be...

Effective methods to prevent weak seedlings during the oilseed rape seedling-raising period
How can weak seedlings be prevented during oilseed rape seedling raising? Please advise. Because oilseed rape seeds are tiny and have a high germination rate, sowing very easily leads to an excessive seeding rate, overly dense emergence, crowded seedlings, and later deterioration of nutrition, poor growth, weak seedlings with elongated stems, and similar problems. After such rape seedlings are transplanted to the field, they have poor stress resistance, slow green-up, and...

What technical points should be noted when raising rapeseed seedlings?
How do you raise rapeseed seedlings? The following techniques can be used for raising rapeseed seedlings: 1. Seedbed preparation: Choose a plot with fertile soil, deep soil layers and convenient drainage and irrigation as the rapeseed seedbed. The ratio of seedbed area to field area is 1:7--8. For seedbed fertilization, organic fertilizer should be the main input, with additional phosphorus and potassium fertilizer. Generally, each mu of seedbed should be applied with decomposed human and livestock manure...
