A Detailed Explanation of 8 Advanced Rice Transplanting Methods
1. Improved intensive cultivation: Transplant young seedlings early at the 3-leaf to 4-leaf 1-heart stage. Fields with a good water source should be planted early, while fields with a poor water source can be planted slightly later. Both dry-raised seedlings and water-raised seedlings are suitable, but in all cases sufficient basal fertilizer should be applied, the soil should be deeply plowed and harrowed level, strong seedlings should be selected as much as possible, and transplanting should be done in shallow water; both row spacing and hill spacing are 1 chi 3 cun, with three single plants per hill spaced 3 cun apart in a triangular arrangement. This transplanting method has density within sparseness and sparseness within density, reducing competition among plants for nutrients and sunlight to the greatest extent, which is beneficial to the individual development of the plants and can therefore greatly increase yield. It is the most advocated transplanting method today.

Detailed Explanation of Key Points for Rice Field Management in August
I. Apply rice field herbicides at the right time. To eliminate weeds in the rice field, rice field herbicides should be applied at the right time. This saves labor (no need for intercultivation) and money (about 2 yuan per mu for chemicals), and can also resolve the conflict of weeds competing with rice seedlings for fertilizer and light, which restricts the normal growth and development of rice seedlings. The specific method is: 5-7 days after transplanting, use 20 grams of Caodaolong or 60-100 grams of Dingbian per mu, mixed with urea (combined with topdressing), fine sand or dry mud powder 30-40 jin, and broadcast after the dew has dried, maintaining a shallow water layer for 4-5 days. II. Achieve scientific fertilization. Late rice in our province

Good results with 30% Aimiao EC on rice
Sheath blight, rice kernel smut, rice false smut and brown sheath rot, among other diseases commonly occurring on rice, have the characteristic of explosive epidemics; once a major epidemic breaks out, it causes severe losses in rice yield, affecting both yield and rice quality. There are many pesticides used in production to control the above rice diseases, but according to our trials, applying 30% Aimiao EC on rice can both ensure disease control efficacy and increase rice yield and improve rice quality. Good disease control efficacy 30% Aimiao EC is compounded from propiconazole and difenocon
