Key Technical Points for No-Till Planting with Rice Straw Return
No-till technology with rice straw return refers to a simple planting method in which, after the rice harvest, the rice straw is spread evenly over the field, no plowing is done, and only chemical weed control is carried out before wheat can be sown. This technology was successfully developed in May 2000 through dedicated experimental research by the Chengdu Second Institute of Agricultural Sciences. The no-till wheat planting technology with rice straw return fully combines the advantages of straw return, no-till, and broadcasting, and scientifically assembles them into a complete new technology package, which has not yet been formally reported at home or abroad. Experimental research shows that this comprehensive supporting technology not only increases

What are the new techniques for summer rice breeding? Key points explained in one article
Summer rice seedling-raising techniques are very important, as the quality of the seedlings directly affects the growth and yield of rice in the field. 1. Select varieties. New rice varieties suitable for local growth should be selected that show good performance in traits such as strong seedling-stage growth, relatively strong tillering, a relatively short growth period, high yield, good glutinous rice quality, white color, and a strong aroma. In the Haiyang area, the main variety suitable for planting is glutinous rice Yizhixiang. 2. Seedbed selection. Plots should be selected that are flat, fertile, easy to manage, and convenient for irrigation and drainage. The seedling field and summer rice area should be managed at a ratio of

Licorice should not be stored for too long; the storage time of medicinal materials must be reasonably controlled
Licorice is generally stored as compressed bales wrapped in burlap, each weighing 50 kg, kept in a dry, ventilated place, with a safe moisture content of 12%-14% for the commodity. There are more than ten kinds of warehouse pests of licorice, including the coffee bean weevil, the brown mulberry borer, and the four-spotted chestnut borer. Fumigation with nitrogen or carbon dioxide for 514 hours can kill all adults and larvae, with no obvious change in the inner quality of licorice. Licorice is prone to mildew. If the air humidity is too high, mold spots or white and green mycelium easily appear on the surface of licorice. The following measures can be taken for prevention and control

Safety Precautions for Wheat and Rice Threshing
Nowadays, combine harvesters are used for wheat and rice harvesting, threshing as they reap and storing the grain in time, but many farmers still use swathers and sickles to harvest, requiring on-site threshing, which poses some safety hazards worth noting. To ensure safe production, the following points should be mastered: 1. Preparations should be thorough. The thresher must be inspected by the agricultural machinery safety supervision department, and only after passing inspection can it be put into operation. Operators must undergo safety training and understand operating techniques and safety knowledge. Before working, a trial run should be conducted first; only after everything is normal

Water-seeded direct-seeded rice has many advantages; what exactly are they?
Depending on the soil moisture conditions at the time of land preparation and the method of land preparation and sowing, direct-seeded rice can be divided into dry direct seeding and water direct seeding. Dry direct seeding can further be divided into methods such as sowing on stubble first followed by shallow rotary tillage, and rotary tillage first followed by sowing. The land preparation and sowing procedure for water direct seeding is roughly as follows: after applying base fertilizer, add water and rotary tillage, open furrows, level the field with water, then sow and press the seeds into the soil. Compared with dry direct-seeded rice, water direct seeding has the following advantages. First, more seedlings emerge and emergence is uniform, which is conducive to cultivating strong seedlings. In water direct-seeded fields, the bed surface is level, and there is mud slurry on top; after pressing the seeds into the soil, no seeds are left exposed, emergence is fast and
