Identification and Control Methods of the Wheat Ear Moth
Scientific name Apamea sordens (Hufnagel), belonging to Lepidoptera, Noctuidae. Also known as the wheat ear worm. Distributed in Inner Mongolia, Gansu, Qinghai and other provinces. Hosts include wheat, barley, highland barley, wheatgrass, and Iris lactea. Damage characteristics: newly hatched larvae first feed on the floral organs and ovary of the ear, and a few feed on the tender inner surface of the glumes; after consuming these they move to cause damage elsewhere. After the 2nd-3rd instar they feed and hide inside the grains; after the 4th instar the larvae move to the flag leaf, spin silk to bind the leaf margins into a tube shape, and after sunset seek out wheat ears to feed.

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 for rice grown with well water is crucial. Specific technical measures: 1. Set up a sunning pond to raise the water temperature. Adding a sunning pond is an effective measure for raising the water temperature of rice grown with well water. The area of the sunning pond should be based on actual conditions and adapted to local circumstances. Generally, the area of the sunning pond is 1500-2000 sq m, and it is appropriate for it to reach about 1/20 of the irrigation area of the pump. According to experimental research, a 2000 sq m sunning

What to Do When Wheat Seedlings Turn Yellow? Common Causes and Control Methods
When wheat grows into the winter and spring seasons, the seedlings often turn yellow or even die, and applying fertilizer alone cannot make them turn green again. There are several types of yellowing in wheat seedlings, and if remedial measures are not taken in time, they can cause serious reductions in wheat yield. Yellowing from pests: yellowing of leaves caused by wheat aphids and wheat mites sucking leaf sap, occurring mainly around the overwintering period. Per 667 sq m, use 65-75 ml of 40% omethoate emulsifiable concentrate mixed with 50 kg of water for spray control. Yellowing from disease: wheat sheath blight damages

How to prevent single-clove garlic? Garlic farmers need to master these management methods
1. For autumn-planted garlic, plow and turn the land immediately after the previous crop is harvested, with a plowing depth of more than 28 cm, plow finely and harrow thoroughly, level the land and make beds. The bed width should preferably be 1.5-2 m, and the bed length generally should not exceed 30 m. For convenience of watering, 20-25 m is preferable. Garlic is a shallow-rooted crop, with shallow roots and weak fertilizer uptake capacity, and it has relatively high requirements for the quality of base fertilizer. Choose a complete-effect, high-quality organic fertilizer and apply it fully in one application. For night soil, do not use raw manure; before application it must be fully decomposed, crushed and mixed evenly, to prevent fermentation in the field, which can cause garlic maggot damage and affect seedling growth and development.

Causes and Control Methods of Dry Shrinkage of the Central Leaves of Hot Peppers
At present, temperatures are gradually dropping, with occasional foggy weather, causing frequent diseases in hot peppers grown in greenhouses. Recently, vegetable growers have often reported problems encountered when growing hot peppers. The problems that have occurred with hot peppers recently are summarized below for the reference of fellow vegetable growers: Dry shrinkage of the central leaves of hot peppers. A vegetable grower from Wutai, Shouguang City, called to ask about dry shrinkage occurring in the central leaves of the hot peppers being grown, and whether it was a viral disease. Dry shrinkage of the central leaves of hot peppers may be caused by a viral disease. Hot

Key Points and Methods for Ginger Storage
1. Storage characteristics: Ginger prefers warmth and moisture and is not tolerant of low temperatures; it is prone to chilling injury below 10°C. Chilled ginger rhizomes rot easily when the temperature rises, and rotting is also easy when the storage temperature is too high. The suitable temperature is about 15°C, and the relative humidity is 65%. Ginger for storage should be harvested when the rhizomes are fully grown and must not be exposed to frost in the field. Generally, it is stored in cellars immediately after harvest and should not be left overnight in the field. It is best not to harvest on sunny days to avoid excessive sun exposure; ginger harvested on rainy days or after rain does not store well. 2. Ginger storage methods: pit burial method and well cellar method: where the soil layer is deep,

What are the methods for preserving garlic bulbs? Practical storage tips to teach you a few tricks
Garlic bulbs do not store well. Even in a dry, ventilated environment, after 100 days of storage they will sprout, shrivel and become moldy, affecting the planting quality for the following year. Therefore, mastering the storage techniques for garlic after harvest is extremely important. Here four garlic bulb storage and preservation techniques are specially introduced: 1. Hanging storage method. After harvest, the fresh garlic bulbs are first sun-dried for 2-3 days; when the leaves become soft, tie the garlic into bunches of 8-10 bulbs each, then hang them neatly under a shade shed or eaves to air-dry naturally. During the hanging storage period, exposure to the sun should be avoided in summer and autumn, and in winter the garlic bulbs should be moved into a ventilated room for storage to avoid moisture and freezing.

Key Technical Points and Application Methods of Wheat Straw and Wheat Chaff Mulching
Wheat straw and wheat chaff mulching involves evenly spreading wheat straw or wheat chaff around autumn crops or between rows to form a certain mulch layer, with an appropriate amount of soil pressed onto it in spots, so as to mulch and preserve soil moisture. For wheat straw and wheat chaff mulching, it is necessary to grasp the timing and mulching amount well, and to apply chemical fertilizers reasonably and according to other such principles. 1. Timing. The relatively suitable mulching time is from late June to early to mid-July. Too early makes it easy to press down the seedlings, while too late means the crop plants are tall and difficult to work with. After mulching, if there is no rain or insufficient rainfall, it will affect the rotting and decomposition of the straw, and the effect will be poor, so watering should be done in time. It can also be done at

Identification methods and control measures for ginger blast
Ginger blast, also known as ginger rot or bacterial wilt, is the most damaging disease in ginger production, generally causing 20-30% losses, and in severe cases destroying the entire crop, and it continues to cause damage during storage, leading to rot. This disease can affect stems and leaves, but mainly damages the underground rhizome. It usually occurs first at the stem base near the ground and the upper half of the underground stem; the lesions are initially water-soaked, dull dirty brown, and the internal tissue gradually softens and rots, leaving only the outer skin. Pressing the diseased part by hand can squeeze out a dirty white, foul-smelling fluid; roots, when affected, also become yellow-brown and rot. After the rhizome is damaged, the underground

Occurrence and Integrated Control Methods of the Eggplant Yellow Spot Borer
Since the 1990s, eggplant has developed rapidly in Jingning County, and the county's planting area has now exceeded 1,300 hectares, with an annual total output of more than 51,000 t. At the same time, the eggplant yellow spot borer has shown an increasing trend of damage in the county, affecting the development of eggplant production. For this reason, the author conducted a preliminary study on the occurrence pattern and integrated control techniques of this pest. 1 Occurrence and damage characteristics The eggplant yellow spot borer, also known as the eggplant borer, belongs to the order Lepidoptera, family Pyralidae. Its larvae bore into and damage eggplant flower buds, stamens, ovaries, tender stems, tender shoots and
