Sorghum downy mildew
Sorghum seedling blight-symptom sorghum can occur when it grows to 4-5 leaves. It begins with the lower leaf and expands upward. The infected leaves produce purplish red stripes and gradually unite, causing the leaves to die gradually from the top and the seeds turn brown. Sorghum seedling blight-pathogen. Fusarium oxysporum, which is called Fusarium moniliforme, is a subphylum fungus. In PDA medium.

Skillful use of growth regulators to promote recovery of sesame
Sesame flowering and capsule stage vegetative growth and reproductive growth at the same time, field management should master the following essentials. Reasonable topdressing at flowering stage can promote flower bud differentiation of sesame. The methods of sprinkling nitrogen fertilizer, foliar spraying phosphorus and potassium fertilizer and boron fertilizer can be adopted. For fields with good soil fertilizer conservation and supply, urea can be applied once at the early flowering stage.

Chasing "three fertilizers" for high yield of sesame
Double-stem cultivation is that the tip of the main stem is removed at the seedling stage of sesame, and the axillary buds at the base of the stem are used to promote the growth of two stalks similar to the original main stem, which can greatly increase the number of pods and increase the yield. Generally increase the income of sesame seeds by about 10 kilograms per mu. Therefore, double-stem cultivation is a new method for high yield of sesame.

There are keys to fertilization for high yield of sesame.
In order to obtain high quality and high yield of sesame, scientific and rational fertilization is the key. Production practice has proved that the key point of fertilizing sesame lies in the grasp of timing and methods, and requires that seedling fertilizer should be "early", bud fertilizer should be "skillful" and flower fertilizer should be "heavy". Let's talk about specific methods for reference. Early application of seedling fertilizer sesame because the seeds are smaller, add.

High yield fertilizer application of sesame
⑴ sesame seed preparation has small seeds, weak root system and slow seedling growth. Fine soil preparation is one of the important measures to sow whole and strong seedlings. Sesame is afraid of waterlogging, so in low-lying and rainy areas, on the basis of ploughing and land preparation, ditches should be made to do a good job of drainage and waterlogging prevention. Tianjin urban area has less rain and snow in spring, sowing sesame seeds in spring, raking and raking in winter.

Sesame should not be planted continuously.
Planting sesame with early crops such as peas, rape and barley has a certain area in our region, which is a great advantage in sesame production. However, in terms of management, it is still in accordance with a set of management methods of summer sesame, so that the latent advantages of early stubble sesame can not be brought into full play, and the output is not very ideal. In order to give full play to its increase.

High-yielding cultivation techniques of cassava in spring
First, dig deeply to improve the soil. A month before planting cassava, turn the soil over and whiten the soil to make the soil fully weathered. When planting, 250 kilograms of phosphate fertilizer composting with livestock manure was applied per mu as base fertilizer. Second, select improved varieties. Varieties with more tubers, less toxicity and high yield must be selected. And select the stem.

How to fertilize sesame seeds
Sesame, also known as oil, is rich in protein and a variety of vitamins and iron, calcium, sesame phenols and other substances, rich nutrition, rich aroma, is an indispensable ingredient for the production of pastries and characteristic food. Sesame oil is a rare excellent edible oil. Sesame is a temperature-loving crop, and July is the best time for autumn sowing of sesame. Zhi.

Key points of cultivation and management of sesame
Most farmers believe that sesame is a low-yield, drought-tolerant crop with extensive management. As a result, the yield per mu of spring sesame is less than 150 kg over the years, and that of summer sesame or intercropped sesame is less than 100 kg. The experiment shows that as long as the improved varieties are added and the cultivation measures are improved, the yield of sesame can be increased by more than 20%. First, Shi.

Why are sesame seeds afraid of repeating?
First, it is expensive to hit the top at the right time. Usually spring sesame retains the first pair of true leaves and summer sesame retains the second pair of true leaves. The experiment shows that this is the best time to top, and the induction rate of double stems is up to 100%. The specific time is: spring sesame in the second pair of true leaves half unfold, summer sesame in the third pair of true leaves half unfold, during which about a week.

Control methods of sesame bacterial wilt
First, the symptoms showed that sesame bacterial wilt occurred early, the root turned brown at the initial stage, the top of the plant drooped, and then dark green patches appeared on the stem, and gradually deepened and blackened. The leaves gradually drooped from top to bottom, the diseased plants were shorter than the healthy ones, the vascular bundles of the rhizomes turned brown, and finally the pith turned into holes. There are bacteria both inside and outside the stem.

Early and rational fertilization of cassava
At present, the cultivation and management of cassava is extensive, there is no distinction between the good and the bad, the yield is low and the economic benefit is poor. In order to obtain high yield in cassava cultivation, the following comprehensive techniques must be adopted: first, selecting improved varieties and improving the coverage rate of improved varieties is the key technology to increase the per unit yield and total yield of cassava. The yield of improved varieties.

High-yield cultivation techniques of cassava
Cassava has a wide range of uses. In addition to food and feed, cassava is also an important raw material for the production of starch, modified starch, wine and grain, glucose, fructose, sorbitol, lysine, citric acid, dyes, coatings, cosmetics and other industrial products. Product value is high and demand exceeds supply. Cassava is coarse and easy to grow, adaptable and fat.

High yield of cassava, good planting and good seedlings
Apply enough base fertilizer. Many people plant cassava on mountains and dry land without applying basic fertilizer and grow anywhere, so the yield is very low. In order to improve the planting efficiency of cassava, we should first turn the ground well, plant distance 1 meter, make good holes, and apply enough mixed fertilizer such as chicken manure, plant ash, waste mud and so on, with a large bowl per hole to lay a good foundation for seedling emergence and long potatoes. Choose a good one.

Occurrence and control of barley yellow mosaic disease
Barley yellow mosaic disease mainly occurred in Hubei, Zhejiang, Jiangsu, Shanghai and Anhui provinces and cities in the lower reaches of the Yangtze River, especially in Jiangsu, Zhejiang and Shanghai. The diseased plant died ahead of time, resulting in the decrease of ear setting rate, seed setting rate, 1000-grain weight, flour yield and quality of barley. Barley happens.

Introduction of barley in different places
1. Seed preparation and sowing rate barley seeds should choose the variety Smur4 with high quality and high yield, and S500 can be used as a matching variety. The sowing amount of corn stubble field is 10m / mu, and that of flue-cured tobacco and corn field is 8m / mu, 8kg / mu. Second, timely sowing barley is not as strict as wheat in sowing time.
