First, choose favorable terrain. In order to reduce the impact of rainstorm on summer sowing vegetables, the land with high topography, fertile geomorphology, loose soil and convenient drainage and irrigation should be selected, and cultivated on high ridge or high ridge.
Second, choose heat resistant and resistant varieties. Summer temperatures are often above 30°C, rainfall is concentrated, and vegetables are generally unbearable. Therefore, heat-resistant Rice varieties should be selected, such as Jinyan No. 2 and No. 7 cucumbers; eight-leaf eggplant and nine-leaf eggplant; Lihong 2 and Qiangmihou. Tomatoes; vine beans; summer cabbage; edible mushrooms and fast-growing vegetables such as cabbage, canola and so on.
Third, do a good job of seedling management. The optimum temperature for the general vegetable seedling stage is 20-28°C, soil moisture is 60-80%, and drought-resistance is not available. The growth and development of vegetable seedlings are greatly influenced by the external environment. Therefore, the key to high yield is to do well in seedling management and seedling cultivation. In order to nurture strong seedlings, control should be given priority, and the combination of stimulating and controlling should be implemented to prevent leggy seedlings and weak and sicklings. When sowing should be selected in the sunny morning or around 4 pm, the soil should be kept moist before and after emergence, not too dry and too wet. Take measures to control the water and fertilizer, and suppress the seedlings to grow in length. Water should be drained in time when water accumulates. When necessary, it can be used to protect the seedlings with soil or scaffolds, and pay attention to cultivating and weeding and pest control.
Fourth, strengthen field management. Strengthening comprehensive management can effectively increase the ability of vegetables to withstand adverse environmental conditions and ensure high yields and stable production.
1, watering: watering can meet the needs of vegetable growth, but also the role of cooling and heat resistance. Watering time should be selected in the early morning or evening, with well water or low temperature river water irrigation, to be poured thoroughly, to keep the soil moist; after the rain should be promptly drained, if necessary, can be used to cool irrigation water 1 times, to prevent hot rain damage.
2. Fertilization: Based on the application of basal fertilizer, supplement fertilizer according to the types, varieties, and needs of different growth stages of vegetables. Nitrogen, phosphorus and potassium should be used in conjunction with the application. If the seedling stage is dominated by nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers, the results will be dominated by phosphorus and potassium fertilizers, supplemented by nitrogen fertilizers. At the seedling stage, the initial stage of the result, and the fruitful stage of the result, the fertilizer should be topdressed once; when the leaves are yellow and weak, potassium dihydrogen phosphate, sprayed fertilizer, and agricultural chemicals can be sprayed on the leaves to prevent premature aging of the leaves.
3. Weeding and Weeding: Weeds are prone to occur in summer, and weeding and weeding must be done in time to prevent weeds and vegetables from competing for light or causing pests and diseases. The cultivator can both weed and protect the roots and promote root development.
4. Prevention and control of diseases and insect pests: The spread of diseases and insect pests in the summer and the prevention and control of pests and diseases are the guarantee for stable production of vegetables. Prevention and treatment of pests should be based on prevention and comprehensive control. For diseases caused by fungi, such as melons, downy mildew, powdery mildew, and blight, they can be controlled by fungicidal agents or broad-spectrum bactericidal pesticides, such as B-aluminum, mancozeb, etc.; The diseases caused by bacteria, such as soft rot of vegetables, bacterial leaf spot of melons, bacterial wilt of Solanaceae, etc., are controlled by the use of bactericidal fungicides, such as agricultural anti-120, anti-virus, carbendazim, etc.; Pests can be used to control insecticides such as net insecticides, enemy killers, and extermination agents, and avermectins and BT biological agents are used to control pests. The effect is also very good. Vegetables that have been sprayed should be listed after the safety interval so as not to affect human health.
There are three main types of rice.
In
GB/T 1354-2009 "Rice National Standards", there are only three types of
rice: glutinous rice, glutinous rice and glutinous rice.
Pick rice three steps
Look
Packed
rice first look at whether the packaging is marked with QS mark,
product name, net content, production date and shelf life, quality
grade, product standard number and other information.
Look at the color and size of the rice grains in bulk to see if there are broken rice or yellow grains.
smell
Premium rice has a natural valley scent and no smell.
taste
New rice has a higher protein content and is harder than Chenmi.
