What s the matter with the girl s rotten seedlings? What should the girl do?

There is a lot of rain in summer, it is easy to appear waterlogging, disease, it is easy to rot seedlings, it is necessary to clean up the diseased seedlings in time, and when the rain is heavy, drain in time. Regularly replenish nutrients and apply fertile leaf foliar fertilizer to promote crop growth.

The maintenance method of mushroom niang.

1. Select the plot: choose the black oil sand soil with medium fertility, loose texture, good structure, easy drainage, shelter from the wind and sun, and thick soil layer to plant mushroom Niang.

2. Stubble selection: Millet and corn are the best crops in the previous crop, because gramineous crops do not have the same diseases as mushroom Niang, they absorb more nitrogen from the soil, less phosphorus and potassium, which is conducive to early maturity of mushroom Niang. Pomineous crops have shallow root system and many fibrous roots, which is conducive to improving soil structure.

3. Land preparation: generally ploughing depth of 25 30 cm. Deep tillage improves soil aggregate structure, soil fertility, aeration performance, soil temperature, water storage capacity, and aerobic microorganisms are active, so as to decompose more effective nutrients, which is conducive to the growth and development of mushroom plants.

After deep ploughing, the spores, pests, eggs, and weed seeds of pathogens can be buried in the deep soil layer, so that the weed seeds lose their germination ability, and the insects, eggs, pupae and some weed roots in the deep soil can be turned over to the surface of the ground to freeze to death, so as to reduce the harm of diseases, insects and weeds. At the same time, deep turning can loosen the soil, which is conducive to the growth of mushroom roots and roots.

4. Ridge formation: Mushroom Niang should be cultivated in large ridges (high furrows), with a ridge spacing of 90 130 cm. Ridge height 25-30 cm.

Large ridges are covered with thicker loose soil, which can reduce water evaporation; Due to the expansion of the evaporation surface, the rainwater is conducive to accelerating the dispersion of water and facilitating drainage and waterlogging. The ground temperature of large ridges and small ridges is 1 3, which is conducive to the growth and development of mushroom Niang. Because the ridge changes the condition of soil water, heat and gas, it also promotes the release of soil nutrients, so that the mushroom Niang develops quickly, matures early for 3 5 days, and increases the yield by more than 5%.

5. After the autumn harvest of the previous crops, immediately remove the residue of the crop, carry out the autumn turning, with the harrowing, when the early spring thaw of the following year is 13 17 cm deep, plough in a timely manner, the fine rake is flat, and the stone stone is suppressed again, and the mushroom Niang is about a month before the base fertilizer is applied to the big ridge.

5. After the autumn harvest of the previous crops, immediately remove the residue of the crop, carry out the autumn turning, with the harrowing, when the early spring thaw of the following year is 13 17 cm deep, plough in a timely manner, the fine rake is flat, and the stone stone is suppressed again, and the mushroom Niang is about a month before the base fertilizer is applied to the big ridge.

Bacterial diseases have to be sprayed with fungicides, mushroom Niangguo is mostly distributed in North China, Northeast China and the middle and lower reaches of the Yangtze River, specifically distributed in Beijing, Tianjin, Hebei Province and Shandong Province in North China, Heilongjiang, Jilin, Liaoning, Northeast Inner Mongolia in Northeast China, Shanghai in the middle and lower reaches of the Yangtze River in the east, Sichuan and Guizhou in the west, Yunnan and Sichuan and other places also grow.

Because it is relatively easy to grow, it is found in most parts of China, such as girl fruit, which is mostly distributed in North China, Northeast China and the middle and lower reaches of the Yangtze River, but with the change of climate and environment, it has become less and less. In addition, in recent years, a large number of girl fruits have been planted, which can be seen not only in the wild, but also in many supermarkets and fruit markets.

Summary. When the plant is too vigorous, remove 5 or 8 leaves on the main stem in time to control the growth. Cultivation points Soil preparation and fertilization Carry out deep soil ploughing, with a depth of more than 25 cm, combined with land preparation and apply 2 000 3 000 kg 667 m 2 of high-quality farmhouse fertilizer that has undergone harmless treatment, rotary land preparation, ridge formation, and suppression, which is completed at one time, and the ridge width is suitable for 60 cm.

When the plant growth is too vigorous, remove 5 residues and 8 leaves on the main trunk in time to control the growth. Cultivation points Land preparation and fertilization Carry out deep soil ploughing, with a depth of 25 cm to the skin, combined with the whole imitation grip and quietly apply the high-quality farmhouse fertilizer 2 000 3 000 kg 667 m 2 after harmless treatment, rotary land preparation, ridge formation, and suppression, which is completed at one time, and the ridge width is 60 cm.

Timely planting when the ground temperature of the greenhouse reaches more than 12 can start planting, generally about 7 days before planting, open 15 20 cm deep ditch on the ridge, apply 5 l0 kg of diammonium phosphate, 25 kg of potassium sulfuric acid, 20 50 superphosphate per 667 m 2 Field management Temperature management After planting in the greenhouse until before harvesting, the temperature is controlled at l5 30, and the temperature difference between day and night is about 10; At the beginning of the harvest period, the temperature is controlled at 18 25 to avoid high temperatures above 32, which is conducive to fruit set. Water managementThe water management of mushroom Niang can not be flooded, and after entering the harvest period, the amount of watering should be small each time. You can't water on a cloudy day in a row, and after a sudden sunny day, you should release the wind and drain the humidity in time.

According to the growth and soil fertility, the fertilizer containing potassium, boron, trime calcium and other elements can be applied 2 3 times in combination with irrigation. When the plant growth is too vigorous, remove the 5 8 leaves on the main trunk in time to control the growth. 5 Pest control.

It's okay to have results, but there will be an impact.

Girl fruit fertilization program.

1. Fertilization: After the plant is planted, you can start fertilizing, you can choose farmhouse organic fertilizer with Ribery Yanwo microbial agent to increase soil nutrients and improve the soil environment, and fertilization should be done to ensure the later growth and storage of nutrients for the plant, and promote the development of Xiaoling Tomb fruit.

2. Watering: When just planting, it is necessary to water sufficiently, so that the root system of the plant can better adapt to the current soil environment, and then each cultivator should also be watered, and the number of watering can also be determined according to climate change, and at the same time, it is also necessary to ensure that the girl fruit grows in a loose soil environment, and timely watering can effectively improve soil temperature and moisture. During the period, the weeds around the sapling should be removed in time to avoid nutrients being absorbed by the surrounding weeds.

3. Cultivating and weeding. At the beginning of planting, it is cultivated once after each watering to loosen the soil, increase the ground temperature, and promote root development. At the beginning of flowering and first fruiting, combined with top dressing, the soil is cultivated to make the cultivation row become a ridge slowly, prevent the lodging of the plant, and is conducive to irrigation and drainage.

Weeding in time in the middle and late stages of growth.
