What are the latest rice breeding technologies? A full analysis of the world's cutting-edge methods
Research on salt-tolerant rice breeding The aims of this research are: 1. To enable new salt-tolerant rice to adapt to cultivation in saline-alkali land. 2. To make full use of seawater irrigation when freshwater is scarce. Abroad, there have been reports of salt-tolerant crops such as tomato, melon and barley. Salt-tolerant rice bred by the University of Sussex in the UK can grow vigorously in the field, but the complexity of regulating salt content in the field must be recognized. Research on genetic engineering of salt-tolerant rice is quite active in the UK. Researchers insert genes from salt-tolerant rice into rice,

Four things to note when harvesting rice, don't overlook these details
The following four points should be noted before and after rice harvest. 1. Drain early. Drain the water in the paddy field as much as possible; if necessary, dig ditches to drain the water in low-lying areas early and dry the field. 2. Harvest at proper maturity. For manual harvesting, do it when more than 95% of the rice husks in the field have turned yellow, the grains have hardened, and the rice grains are translucent. Mechanical harvesting can be a few days later. 3. Mind the method. Manual cutting and drying can increase the 1000-grain weight and raise yield, while the rice grain has good market quality and a high germination rate. When using a combine harvester, it is best

Key Technical Points for Post-Flood Care of Submerged Rice
After rice is submerged, in view of the actual situation of severe damage to the root system and leaves and a serious decline in the total number of stems and tillers, measures should be taken to nourish the roots, protect the leaves and promote tillering, so as to increase the percentage of productive panicles and strive for heavier grains. 1. Make an all-out effort to drain the standing water from the fields. The standing water in the fields should be drained as early as possible, and the fields should be exposed and the seedlings hardened to improve the soil's physical and chemical properties and remove toxic substances. For fields submerged for a relatively long time, the water can be drained completely in one go during rainy weather; in hot weather with strong sunlight, dehydration should be carried out gradually, first allowing the upper part of the rice plants to emerge above the water surface, then dehydrating at night to aerate the soil, and irrigating by day and exposing at night, so as to help the rice recover its growth. 2.

Rice management aims to nourish the roots, protect the leaves and promote tillering
Wang Shengxuan, associate researcher at the Grain Crops Research Institute of the Provincial Academy of Agricultural Sciences, believes that every year when the rainy season arrives, regional heavy rainfall occurs in the rice-growing areas in both the north and south of the province, and waterlogging causes disasters in some areas, especially for rice planted in lower-lying paddy fields, where some rice seedlings are submerged to the top. After being flooded, the rice root system and leaves are severely damaged, the plant's normal physiological metabolism and stress resistance are severely weakened, and the total number of stems and tiller seedlings drops sharply. If flooded paddy fields do not receive timely and effective management, it will inevitably cause a large reduction in yield, or even a total loss. Therefore, scientific remedial measures must be taken promptly for flooded paddy fields

What are the control methods for early heading in rice?
This year, the Yangtze River and Huai River basins have experienced persistent drought with little rain, causing severe impacts on agricultural production. In July-August, rice in the rice-growing areas north of the Yangtze River and in the Huai River basin showed "early heading" to varying degrees. Field performance: 2-3 early heads per hill, differing from late-developed tillers by more than 7-10 days, clearly showing "second flush heads" or "third flush heads". To make up for the losses caused by "early heading" to field production as early as possible, the causes of early heading are analyzed below, and rescue methods are proposed. The length of the rice seedling age is closely related to the early heading phenomenon.

Simple Diagnosis and Control Methods for Rice Deadheart
I. Simple Diagnosis of Rice "Deadheart" 1. "Deadheart" caused by insect pests. Sesamia inferens, Chilo suppressalis, Scirpophaga incertulas, mole crickets and other pests damaging rice can all cause "deadheart," and the main differences are: (1) Sesamia inferens: the insect holes are large and there is much frass, and the frass is generally deposited between the rice leaf sheath and the stem. The leaf sheaths and leaves of the damaged rice all turn yellow. The damage is more severe at the edges of the rice field and lighter in the middle of the field. (2) Chilo suppressalis: after the eggs hatch, the young borers first gather inside the rice leaf sheath to feed and cause damage; on the outside of the damaged leaf sheath, water-soaked yellow spots first appear, then it gradually turns yellow

How to Make Ginger-Garlic Spicy Shrimp, Fresh and Fiery, Perfect with Rice
Several white shrimp, split along the back. Main seasonings: dried chili peppers, a handful of Sichuan peppercorns, ginger and garlic sliced, scallions shredded, a few pickled chili peppers, and a piece of pickled ginger also sliced. Pour oil into the wok, remember to use a bit more, about double the oil you'd use for stir-frying the same amount of meat dish over high heat until the oil is hot, then add the shrimp. Stir-fry for a bit, add the dried chili peppers and Sichuan peppercorns, and keep tossing so the hot oil "squeezes out" both the spicy and numbing flavors. Once the spicy and numbing flavors come out, add the ginger and garlic slices, pickled peppers, and pickled ginger (don't add the scallions yet). After the ginger-garlic aroma is released, add an appropriate amount of soy sauce, an appropriate amount of white sugar, and a little cooking wine

Retained placenta in livestock can be treated by boiling Angelica sinensis in sweet rice wine
Retained placenta in livestock is a relatively common condition among obstetric diseases. Under the guidance of my father, the author has used Angelica sinensis boiled in sweet rice wine to treat retained placenta in livestock, with obvious results. "Angelica sinensis," which some farmers call "blood skin vegetable," has been used by the author since 1988 to treat 22 cases of retained placenta in yellow cattle and water buffalo, 1 case of retained placenta in a dairy cow in June last year, and 1 case of retained placenta after miscarriage in livestock (a pig) in May this year, all with practical results. This medicine is simple to use, economical, and convenient, and is hereby reported as follows for the reference of colleagues. 1 Drug processing

Detailed Explanation of the Method and Technique for Brewing Yellow Rice Wine from Potatoes
Potatoes are rich in starch and highly nutritious. Using potatoes as the raw material to brew yellow rice wine not only keeps costs low but also produces good wine quality. 100 kg of potatoes can yield about 85 kg of 50-proof yellow rice wine. Pretreatment. Wash and peel potatoes that are free of pests, disease and rotten spots, then put them in a pot and boil. After taking them out and letting them cool, pour them into a large earthenware vat or stainless steel pot and mash them into a paste with a wooden stick. Prepare the starter material. For 100 kg of potatoes, use 100 g each of Sichuan pepper and fennel, add 20 kg of water, bring to a boil over high heat in a pot, then simmer over low heat for 30-40 minutes. Take out and cool
