What to do if hollow vegetable suffers from white rust
① selected disease-free seeds or mixed seeds with 0.3% seed weight of Manganese Zinc. ② the disease is only limited to infect Convolvulaceae vegetables. After 2-3 years of rotation, the disease control effect is good. ③ should pay attention to the discharge of stains in the field and ventilation of sparse plants. ④ sprayed 48% metalaxyl manganese zinc wettable powder and 40% metalaxyl copper wettable powder at the initial stage of the disease.

Brown spot of Chinese cabbage
The symptoms were yellow-brown dots at first, and then expanded into round to oval, or irregular black-brown spots with a diameter of 4mm and obvious edges. When the disease is serious, the disease spots are connected to each other, and the diseased leaves wither and die. The disease occurs easily in rainy and humid weather or out-of-season cultivation. The method of prevention and control.

Two methods of killing underground pests of sweet potato
Sweet potatoes are damaged by underground pests, will be full of insects, can not be processed and eaten, and accelerate decay, resulting in a reduction in production. In production, the following methods can be taken in time for poisoning control in order to improve yield and quality. First, Benedict. During the growth and development of sweet potato, 1000 was sprayed on the leaves every 15 days.

Measures to prevent diseases and insect pests of asparagus
1. Make seedlings: when the branches growing from the nodes are 20 cm long, cut off the seedlings with fibrous roots as seedlings. 2. Cultivation methods: prepare braided grass ropes, wooden stakes and floats (plastic foam spherical flotation for fish net). When planting, press the seedling to 15ml / 20cm.

Off-season cultivation techniques of water spinach (Ipomoea aquatica)
Due to the high temperature and heavy rain after the beginning of summer, a kind of white rust is easy to occur. The control methods are as follows: (1) choose disease-free seeds and seed treatment: select disease-free land to keep seeds, soak the newly bought seeds in 50 ℃ warm water for 25 minutes, cool and sow seeds. (2) strengthen the management of garden fields: select high terrain and drainage.

How to manage asparagus in solar greenhouse
After planting or direct seeding of asparagus seedlings, ploughing and loosening the soil should be carried out many times in order to increase the ground temperature, promote rooting and remove weeds in the field. Asparagus seedlings need less water at seedling stage and can be irrigated properly. The soil should be kept moist after harvest. After the first harvest, 15 kg of urea or diammonium phosphate per mu.

How to control white rust of hollow cabbage
1. Rotation with other vegetable varieties for 2 to 3 years. Second, before sowing, seed sterilization is carried out according to the proportion of 100kg seeds 300g and 35% metalaxyl; third, at the initial stage of the disease, 6000 to 7000 times solution of 50% nail cream copper wettable powder is used, or 72.2% Pulic water agent 8000 times solution is sprayed, once every 7 to 10 days.

How to control "white rust" of asparagus
Due to the high temperature and rain after the beginning of summer, asparagus is prone to white rust. Once the disease occurs, it not only reduces the yield, but also affects the quality. First, at the beginning of the onset of the symptoms, the disease spot appears yellowish to yellow spot on the front of the leaf, then gradually browns, the disease spot is larger, and the back of the leaf is white blister-like spot, nearly round or elliptical.

Control techniques of sweet potato diamondback moth
Spodoptera litura belongs to the family Lepidoptera, which mainly harms sweet potatoes. The larvae eat the leaves and tender stems of sweet potatoes, and when serious, they can eat up the leaves, which has a great impact on the yield. There are 3-4 generations a year in Henan Province, overwintering with pupae at a depth of 10 cm under the soil. Feathering in May of the following year.

How to manage Sweet Potato to achieve High yield
High-yield cultivation and management techniques of sweet potato: first, apply sufficient base fertilizer, reasonable soil preparation 1. Fertilization: as sweet potatoes are generally planted on thin sandy land, it is necessary to apply sufficient base fertilizer and improve soil fertility in order to obtain high yield. Generally speaking, about 5 mu of soil and miscellaneous dung, 25 kg of diammonium phosphate and 25 kg of potassium sulfate are appropriate. 2. The whole.

Harvesting sweet potatoes also has skills.
Sweet potato is a vegetative vegetative body, and there is no obvious maturity standard and harvest time, but the harvest sooner or later has an effect on the yield, seed retention, storage, processing and utilization of sweet potato and crop rotation. Harvest too early, will significantly reduce the yield of sweet potato; harvest too late, sweet potato is often affected by low temperature chilling injury, not resistant to storage, cutting.

How to plant autumn sweet potato in a rush
Sweet potato is vulnerable to underground pests, forming insect pathways, so that sweet potato rot, reduce the quality, serious can not be eaten, resulting in reduced production and loss of harvest. In production, the following methods can be taken in time for poisoning control in order to improve yield and quality. 1. During the rapid expansion of sweet potato, 25-30-fold phosphorus was applied to the root every 10-15 days.

Controlling the growth of sweet potato can promote high yield.
Sweet potato is a kind of crop with high and stable yield. It has the characteristics of wide adaptability, strong stress resistance, drought and barren tolerance, less diseases and insect pests and so on. When planted in places with better water and fertilizer conditions, the general yield per mu can reach 2000Mui 3000 kg. However, due to the differences in natural conditions and cultivation level, the level of per unit yield is also extremely unbalanced, in order to give full play to.

This kind of potato seedling basically has no yield in the later stage. After investigation, the main reason is the serious occurrence of sweet potato virus disease. Sweet potato virus disease is a common disease of sweet potato.

Key points of raising seedlings of asparagus in spring
Asparagus production generally adopts seedling transplanting, and the seedling emergence rate of centralized seedling transplanting is high, which can save seeds, reduce costs, facilitate centralized management, help to control diseases and insect pests and cultivate strong seedlings, prolong the growth period of the planting year and increase the yield of the second year. Seedlings can be oriented according to the growth direction of asparagus.
