How good is the Super Large Grain King rice variety?
Zhezao 15 is a super-high-yield early indica rice new line developed by mutagenesis treatment using the super-high-yield genetic advantage of "Zhe 18500". After multi-point trial planting as early rice by the Zhejiang Academy of Agricultural Sciences, the yield generally reaches more than 600 kg per 667 sq m (1 mu). The characteristics and advantages of Zhezao 15 are introduced as follows: 1. Extremely strong tillering ability, low seed requirement. The effective tillers per plant can reach 12-15, and 1 kg of seed per 667 sq m of field is sufficient. 2. Cold tolerance at the seedling stage, disease resistance at the later stage. Strong cold tolerance at the seedling stage, so sowing can be appropriately advanced

Practical methods for raising water temperature when growing rice with well water
The biggest drawback of growing rice with well water is the low water temperature, which affects the good growth and development of rice, leading to reduced yield and poor quality. Therefore, raising the water temperature when growing rice with well water is crucial. The specific technical measures are: 1. Set up a solar warming pond to raise the water temperature. Adding a solar warming pond is an effective measure to raise the water temperature when growing rice with well water. The area of the solar warming pond should be based on actual conditions and adapted to local circumstances. Generally, the area of the solar warming pond should be 1500-2000 sq m, preferably reaching about 1/20 of the irrigation area of the pump. According to experimental research, 2

What are the reasons why rice seedlings are slow to tiller?
1. Rice bakanae disease: Disease pattern and transmission routes: The pathogen of rice bakanae disease overwinters on grains and rice straw. The following year, when diseased seeds or straw are used, the pathogen multiplies as the seeds germinate, invading through the seedling coleoptile or wounds, causing the seedlings to develop the disease and become leggy. Diseased seedlings often wither and die. Diseased seedlings that do not die are pale yellow-green, grow thin and elongated, generally about one-third taller than healthy seedlings; their roots develop poorly, with few tillers or even no tillering. After diseased seedlings are transplanted, they carry the pathogen to the field, causing rice plants to develop the disease. When rice heads and flowers

Stir-fried Tea Tree Mushrooms with Scallops in Teriyaki Sauce: fresh, fragrant and savory, perfect with rice
"Stir-fried Tea Tree Mushrooms with Scallops in Teriyaki Sauce" is a stir-fry with a Japanese touch. The "teriyaki sauce" here is Japanese-style "meat teriyaki sauce," though a Korean-made version can also be used, and the taste will not differ much. Some old friends think this kind of sauce is a "professional" seasoning, so they rarely buy it to use at home. In fact, it is a very widely used sauce; besides Korean and Japanese cuisine, it is also commonly used in Chinese and Western cooking. This teriyaki sauce can be used to cook fish, meat, vegetables and mushrooms, mostly by pan-frying, stir-frying, braising and simmering. At home, you can use teriyaki sauce to make stir-fries and some

Farmer in Deqing, Zhejiang Invents New Method of Rice Cultivation
Planting rice in paddy fields after raising soft-shelled turtles, keeping it inside insect-proof netting throughout the entire growing period... A farmer in Deqing County, Zhejiang Province, has invented a new method of growing rice that requires no fertilizer or pesticide. Not long ago, a green, pollution-free rice produced in Deqing and called "Mosquito Net Rice" aroused great interest; rice priced at 36 yuan per kilogram sold out in just over an hour, and many rice shops in Hangzhou even placed advance orders for 2008 stock. Why is it called "Mosquito Net Rice"? It turns out that this

Rice seedling raising is key: good seedlings mean half the rice is already grown, and strong seedlings lead to high yields.
Seedling-stage management for machine transplanting is key. Cultivating robust seedlings suitable for machine transplanting is the key to the success of promoting mechanized rice transplanting. "Good seedlings mean half the rice is grown, and strong seedlings lead to high yields." The quality of the seedlings plays an important role in the number of panicles, number of grains and grain weight in the later growth stages of rice. The basic requirements of mechanized transplanting for seedlings are overall uniformity and individual robustness, requiring that "a tray of seedlings has no tall and short ones, and a handful of seedlings has no thick and thin ones." High temperature and high humidity promote uniform emergence. Germinated rice seeds, after sowing, need to go through a period of high temperature and high humidity for seedling establishment.

How to control rice thrips? Control methods and technical key points
(1) Life habits: The rice thrips is very small, with adults only 1 mm to 1.5 mm long, dark brown. In winter, adults overwinter in gramineous weeds and on wheat crops. During the seedling-raising period of the following year, when the seedlings grow to 2 to 3 leaves, they fly into the seedling fields to lay eggs and reproduce. The insect body is small and very active, able to fly and jump. Adults are attracted to green, and after the seedlings are transplanted, they enter the tillering stage when food is abundant, which facilitates massive egg-laying and reproduction, damaging the heart leaves and young tender tissues. In the early stage of leaf damage, small white spots appear, and the upper part of the leaf tip curls inward, causing
