Scientific Fertilization Methods and Technical Points for Plum Cultivation
I. Fertilizer Types 1. Base fertilizer: Base fertilizer is a fertilizer that can supply plum trees with various nutrients over a relatively long period. It is generally dominated by slow-release farmyard manure, such as compost, barnyard manure, crop straw, green manure, fallen leaves, etc. An appropriate amount of quick-acting nitrogen fertilizer can be added to the base fertilizer to meet the large amount of nitrogen needed by plum trees during early spring germination and flowering.

What are the control methods for grub pests in Welsh onion?
Welsh onion is a type of scallion, belonging to the genus Allium in the lily family. It is the stem and leaves of the perennial herbaceous plant scallion, with green scallion leaves on the upper part and white scallion stalks on the lower part. It can be divided into four types: common Welsh onion, bunching onion, shallot, and proliferous onion. Zhangqiu in Shandong is China's largest Welsh onion planting, ⟦4 <p>Welsh onion is a type of scallion, belonging to the genus Allium in the lily family. It is the stem and leaves of the perennial herbaceous plant scallion, with green scallion leaves on the upper part and white scallion stalks on the lower part. It can be divided into four types: common Welsh onion, bunching onion, shallot, and proliferous onion. Zhangqiu in Shandong is China's largest base for Welsh onion planting, processing, and export, and currently mainly grows Japanese varieties of Welsh onion. Welsh onion is pungent in taste and slightly warm in nature, with the effects of inducing sweating and unblocking yang, and detoxifying and flavoring. It is mainly used for wind-cold common cold, aversion to cold with fever, headache and nasal congestion, cold pain in the abdomen, dysentery and diarrhea, internal obstruction from parasitic accumulation, insufficient lactation, and difficult urination and defecation. Welsh onion contains volatile oil, the main component of which is allicin, and also contains diallyl sulfide and calcium oxalate. In addition, it also contains fat, carbohydrates, carotene, vitamins B and C, niacin, calcium, magnesium, iron, and other components.</p><p></p><p>Scallion has the effects of benefiting the lungs and unblocking yang, inducing sweating and releasing the exterior, promoting lactation and stopping bleeding, and relieving pain and healing injuries. It is used for dysentery, abdominal pain, arthritis, constipation, and other conditions. Scallion has a unique spicy aroma, derived from the volatile sulfur compound scallionin, which can stimulate the secretion of saliva and gastric juice and increase appetite. The malic acid and phosphoric acid sugars contained in scallion can excite the nerves, improve and promote circulation, and release the exterior and clear heat. Eating scallion regularly can reduce the accumulation of cholesterol on blood vessel walls.</p><p>Its nutritional benefits cannot be fully described in just a few words. It can be said that Welsh onion has many dietary therapeutic effects. Eating Welsh onion or chives 3 times a week, whether stir-fried, served cold, or used as a seasoning, can achieve the effect of tonifying yang and nourishing yin. Tonifying yang and nourishing yin: the various vitamins in Welsh onion can ensure normal secretion of human hormones and can also effectively stimulate libido, thereby “tonifying yang and nourishing yin.”</p><p>Detoxifying and flavoring: Welsh onion is pungent in taste and slightly warm in nature, with the effects of inducing sweating and unblocking yang, and detoxifying and flavoring. It is mainly used for wind-cold common cold, cold pain in the abdomen, aversion to cold with fever, headache and nasal congestion, insufficient lactation, and difficult defecation. Welsh onion contains volatile oil, the main component of which is allicin, and also contains diallyl sulfide and calcium oxalate. In addition, it also contains fat, carbohydrates, carotene, vitamins, niacin, calcium, magnesium, iron, and other components.</p><p>Inducing sweating and inhibiting bacteria: Welsh onion can stimulate the body's sweat glands to achieve the effect of inducing sweating and dispersing heat; scallion oil can stimulate the upper respiratory tract and make sticky phlegm easier to cough up. The allicin contained in scallion has a clear effect against bacteria and viruses, especially stronger inhibitory effects on Shigella dysenteriae and skin fungi.</p><p>Preventing cancer: the pectin contained in chives can significantly reduce the occurrence of colon cancer and has an anti-cancer effect. The allicin in scallion can also inhibit the growth of cancer cells; scallion also contains the trace element selenium, which can reduce the nitrite content in gastric juice and has a certain effect on preventing gastric cancer and multiple types of cancer.</p><p>Control of the Welsh onion pest grubs</p><p>Grubs are important underground pests. They have large heads, brown or yellow, with a few black, so farmers call them big-head worms. Their bodies are smooth and wrinkled, generally white, with legs, and they can crawl, but they play dead; when touched, they curl into a “C” shape, commonly known as white soil silkworms. They live exclusively in the soil and damage the underground parts of plants. Grubs are the larvae of scarab beetles. In our province, the main species are the North China black scarab beetle and the copper-green scarab beetle, so grubs are a mixed population. From June to August each year, scarab beetles emerge from the soil to lay eggs. Because most grubs overwinter and survive, after years of accumulation, there is a peak of damage in autumn. When the winter temperature drops to about 8 degrees, grubs burrow deep into the ground, and rise again to cause damage the following spring.</p><p>In the face of severe pest outbreaks, comprehensive measures should be taken to control grubs:</p><p>1. Set up insect-killing lamps in concentrated planting areas, turn on the lamps at night from June to August to trap and kill scarab beetles and reduce egg-laying.</p><p>2. After harvesting Welsh onion, plow the soil deeply to mechanically kill some grubs.</p><p>3. Chemical control: use 500 milliliters of 48% Lorsban emulsifiable concentrate per mu, or use phoxim. Because 48% Lorsban remains in the soil for a relatively long time, it has good control efficacy against underground pests. It can be mixed into medicated soil and spread along the rows, then watered, or poured into the soil with irrigation water. Note: it is strictly prohibited to use highly toxic methamidophos, 1605, and others.</p>
