How to prevent empty and blighted rice grains? Master these technical measures
Empty and blighted rice grains refer to unfertilized empty grains and half-empty grains that fail to develop after fertilization, and this has a great impact on rice yield. Therefore, in rice production, in addition to striving for more panicles and larger panicles, it is also necessary to reduce empty and blighted grains, improve the seed-setting rate, and increase the 1000-grain weight in order to obtain high yields. At present, rice is in the grain-filling and ripening stage. To prevent the occurrence of empty and blighted rice grains and achieve the goal of high yield, comprehensive preventive measures must be taken. The specific measures are as follows: 1. Select varieties with good seed setting. Rice varieties differ in physiological morphology, and the seed-setting rate varies greatly.

How to carry out mid-season cultivation management of rice? Detailed technical measures for Eryuan County
From last autumn to June this year, Eryuan County experienced continuous drought and high-temperature weather, causing varying degrees of loss to small spring crops and preventing some large spring crops from being sown normally. The county agriculture bureau adopted various scientific and technological measures to actively respond to natural disasters such as the severe drought, striving to "compensate small spring losses with large spring gains" and achieve the annual production target. In rice production, it grasped key measures such as good seeds and good methods, dry seedling raising with sparse planting and shallow transplanting, soil testing and formula fertilization technology, precision quantitative cultivation technology, and high-yield creation. Scientific and technical personnel went deep into the front line of agricultural production, firmly grasped technical

What are the key technical points for garlic cultivation? A detailed explanation in one article
Garlic is a bulb vegetable of the onion family, with strong cold tolerance, an optimum growth temperature of 12-25°C, and is a long-day crop. It is suitable for planting in fertile, slightly alkaline soil rich in organic matter with convenient irrigation and drainage. To grow garlic, the main steps to get right are as follows: (1) Variety selection. At present, the main varieties suitable for planting in Qilin District are Sichuan Red Seven Stars (first generation, second generation), Soft-leaf Garlic, First-grade Early, Second-grade Early, local purple-skin garlic, etc. (2) Sowing time. In the flat basin area, early garlic sprouts and Red Seven Stars (first generation, second generation) are generally planted around the White Dew solar term (early September

Methods and key technical points for rational close planting of garlic
How should garlic be rationally close-planted? Before sowing, the planting density must first be determined, that is, the number of plants per mu. According to trials in the Cangshan garlic production area, on plots with medium to high production levels, planting 30,000 plants per mu yielded 686.7 kg of fresh garlic bulbs; planting 40,000 plants per mu yielded 920 kg of fresh garlic bulbs, a 33.9% increase over planting 30,000 plants; planting 45,000 plants per mu yielded 526.7 kg of fresh garlic bulbs, a 23.3% decrease. The trials found that when the number of plants per mu exceeded 40,000, although the yield increase was significant, the commercial

Garlic Seed Selection and Saving Methods and Key Technical Points
Garlic is propagated by using the bulbs as seed. For seed saving, choose bulbs with thick, sturdy stalks, deep green leaves, a good root system, no pests or diseases, and that are large and plump. At the same time, pay attention to timely harvesting. If the bulbs are harvested too early, the cloves will not be plump or firm, and when planted the following year they will have weak germination vigor, uneven emergence, and leaves that curl into tubes without opening; if harvested too late, the outer skin of the bulbs will split, and many cloves will scatter. The harvest time is generally best 25-30 days after the garlic scapes are harvested. At harvest, the aboveground part should have four or five leaves, the cloves should be countable by hand as raised bumps, and the outer skin should be purplish red. When harvesting garlic bulbs, you must

Detailed Explanation of Garlic Storage Methods and Technical Points
The key to garlic storage is creating suitable environmental conditions for dormancy, inhibiting sprouting and rot. The ideal environmental conditions for garlic storage are: low temperature, low humidity, and ventilation. The most suitable temperature is around 0°C, and the relative humidity is 70-80%. Its simple fresh storage requires no special or complex process equipment, and even more so no fixed storage site; it adapts to local conditions, uses local materials, has a simple process, and is low in cost. The storage time can reach 7-8 months. Storage methods include hanging storage, rack storage, and pit storage. 1. Hanging storage: After harvest, the garlic must

Key Technical Points for High-Yield Cultivation of Green Food Garlic
1 Site Conditions for Green Food Garlic The green food garlic base should be far from cities, industrial and mining areas, and main traffic lines, and there should be no "three wastes" (waste gas, wastewater, and industrial residue) discharging enterprises in the base area and its surroundings. The farmland atmospheric environment should be good, and the irrigation water quality and soil environmental quality should both comply with the "Environmental Quality Standard for Green Food Production Areas." Soil suitable for garlic growth should have a deep plow layer and fertile texture, with organic matter content above 1.0%, and loam is best. 2 Planting of Green Food Garlic 2.1 Land Preparation The plowing depth is generally about 20 cm, and the soil should be finely cultivated,

How to prevent and control peach leaf curl? A detailed explanation of practical technical points
I. Symptoms and damage. This disease occurs from time to time in the south, and when severe it causes branch dieback and affects ornamental value. The disease mainly damages leaves. When leaves unfold in early spring, the leaf margins curl downward, and the diseased leaves become blistered in part or entirely, the leaves thicken, become brittle in texture, and turn yellow or red, with the leaves distorted and deformed. In early summer, a grayish-white powdery layer forms on the diseased parts, and when the disease is severe the leaves fall early. When young shoots are damaged, they appear grayish-green or yellow, with short and thick internodes and slight curvature; the upper leaves cluster and curl. When the disease is severe, the branches die.

Processing Methods and Technical Key Points for Lily Beverage
Process flow: sorting, separating scales → washing → draining, weighing → pulping → pretreatment → refining → coarse filtration, standing for sedimentation → drawing off clear liquid → blending → fine filtration → high-pressure homogenization → degassing → filling → can sealing → high-pressure sterilization → holding → wiping cans → inspection → labeling → warehousing. Key points of process operation: (1) Sorting, separating scales: sort the purchased fresh lilies, separate the scales, and remove rotten scales, stem bases and other impurities. (2) Washing: pour the sorted lily scales into a water tank for washing to remove mud, sand and other impurities,

Lily Leaf Blight: Control Methods and Key Technical Points
Symptoms: Circular or oval lesions form on the leaves, varying in size, with a length of 2 to 10 mm or more. They range from pale yellow to light brown. In some varieties, the spots are light brown, surrounded by a distinct reddish-purple margin, and under humid conditions the spots quickly become covered with a layer of gray mold. When dry, the lesions become thin, easily crumble, are transparent, and generally appear grayish-white. In severe cases, the entire leaf dies. When the stem is infected, it rots and breaks at the point of infection, and the buds turn brown and rot. Spots on the flowers are brown and, when moist, quickly become a sticky mass covered with a gray
