What are the reasons rice seedlings are slow to tiller
1. Rice bakanae disease: Patterns of occurrence and routes of transmission: The pathogen of rice bakanae disease overwinters on grains and rice straw. The following year, if infected seeds or rice straw are used, the pathogen multiplies as the seeds germinate, invading through the coleoptile or wounds of the seedlings, causing the seedlings to develop the disease and grow excessively tall. Affected seedlings often wither and die. Infected seedlings that do not die are pale yellow-green, grow thin and elongated, generally about one-third taller than healthy seedlings; root development is poor, with few tillers or even no tillering. After infected seedlings are transplanted, they carry the pathogen into the field, causing rice plants to develop the disease. When rice heads and flowers,

Can emamectin benzoate control the rice leaf roller?
Emamectin benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized starting from the fermentation product avermectin B1. It has the characteristics of biological pesticides such as ultra-high efficiency, low toxicity (the formulation is nearly non-toxic), no residue, and no pollution. Compared with avermectin, its insecticidal activity is first increased by 1-3 orders of magnitude. It has extremely high activity against the larvae of Lepidoptera insects and many other pests and mites. It has both stomach poison action and contact action, and has very good effects at very low doses (0.084~2g/ha), and in the process of controlling pests it is harmless to beneficial

Detailed Explanation and Application of the New Muskmelon-Rice Multiple Cropping Technique
I. First Crop Muskmelon 1. Seed selection and land preparation: Choose high-yield, high-quality muskmelon varieties with a growing period of about 90 days, such as Chaozhao Tangwang and Hongchengcui No. 1. Before the ground freezes the previous year, plow the paddy field well, harrow, press and form ridges with a ridge spacing of 50-60 cm, and press firmly to preserve soil moisture. Along with land preparation, apply 5000 kg of high-quality farmyard manure per mu. 2. Seedling raising and transplanting: Soak seeds to promote germination in late February, raise seedlings in a greenhouse in late February to early March. You may use seedbed seedling raising followed by pricking out into seedling bowls, or directly raise seedlings in seedling bowls. For planting melons in the main field, transplant the melon seedlings into the main field before April 15.
