Experimental Study on Factory-Scale Rapid Propagation Technology of Potato Test-Tube Plantlets
For many years, farmers' own propagation, self-breeding and seed retention have caused potato yields to decline year by year during production, quality to deteriorate, and commercial appearance to worsen. Scientists have proven through research that virus infection and its accumulation in tubers are the main causes of potato "degeneration." To solve the problem of severe degeneration and reduced yield of the main potato cultivars in our city, our institute made virus-free potato production a key experimental project and conducted experimental research on the problems existing in virus-free production, thereby utilizing resources and reducing production costs.

Large-scale leaf-rolling of the central leaves of rice may be related to excessive application of quinclorac
For some time recently, hundreds of readers across our province have called to report large-scale leaf-rolling of the central leaves of rice seedlings, which is even more common in direct-seeded rice production. Many readers brought in diseased plants. The root systems of the diseased plants are generally fairly normal, and there are no obvious disease spots or other symptoms on the leaves. After examining the submitted diseased plants, relevant experts from the Institute of Plant Protection of the Provincial Academy of Agricultural Sciences and other units preliminarily diagnosed that the leaf-rolling of the central leaves of rice is not caused by viruses or other pathogenic microorganisms, but may be phytotoxicity caused by herbicides such as 2,4-D and quinclorac, or may be caused by physiological

Large-scale propagation of the new high-quality wheat variety Emai 18 succeeds in Hubei
The new wheat variety "Emai 18", which combines high quality and special purpose, high yield, multi-resistance and early maturity, has been successfully propagated on a large scale in Hubei. This variety fills the gap of the absence of medium-gluten wheat in the middle and lower reaches of the Yangtze River, and won the first prize of the Hubei Provincial Science and Technology Progress Award in 2005. According to Li Meifang, a researcher at the Hubei Academy of Agricultural Sciences who bred "Emai 18", "Emai 18" is Hubei's first wheat variety to organically combine four major target traits: high quality and special purpose (reaching the national medium-gluten standard for special-purpose wheat varieties), high yield (yield increase of 8.75%), multi-resistance (moderate resistance to stripe rust and powdery mildew), and early maturity (

What are the techniques for large-scale production of export white bunching onions in the Chongming area?
1 Variety selection Select varieties such as Changbao, Changyue and Chunwei according to the export specifications and timing requirements for white bunching onions. For example, Changyue bolts late and has strong tolerance to heat and cold; it can be planted densely, planted from March to May, and harvested from November to January of the following year. 2 Raising seedlings 2.1 Preparation of the seedbed Seedbed preparation procedure: prepare the field (deep ploughing 350m, freeze the soil clods) -> apply base fertilizer -> plough twice (25cm) -> make beds (bed surface specification 1.5m x 30m). Applying base fertilizer: about 20 days before sowing, apply biological

High-yield technique for large-scale film-mulched spring peanut sowing with pod sowing, moisture borrowing and dry sowing
Pod sowing with film mulching is an effective measure for early sowing of spring peanuts by borrowing soil moisture, ensuring full stands, resisting drought and increasing yield. The Agricultural Technology Extension Center of Linmu County began trials and demonstrations in 1987, and from 1992 to 1993 the implemented area reached 8,520 hectares, with average unit yields reaching 3,982.5 kg/ha and 4,057.5 kg/ha, increases of 13.9% and 16....
