It can absorb water and nutrition. To meet the needs of leaf transpiration and results. Absorb nitrogen, phosphorus, potassium and trace elements to meet various physiological needs of vegetable plants. Therefore, it is not easy to break, and the injured leaves can be cut. If the garlic moss is harvested in rainy days or after rain or in the morning, due to the large water content, the plant has fully absorbed water, and the toughness of the garlic moss and leaves is poor, which is very easy to break.

 

It can not only significantly improve the aggregate structure and physical and chemical properties of 20cm plastic plant pots soil, inhibit the occurrence of vegetable root diseases (especially for various soil borne diseases), but also increase production and income. Spraying boron fertilizer boron is a necessary nutrient element for the normal development of plant flower organs and reproductive organs. In sandy soil and soil with serious boron deficiency, 1kg of borax can be applied per mu as base fertilizer or seed fertilizer.

 

Wax peony is a very good horticultural variety. Wax peony needs plenty of sunshine and a cool and dry environment. It is resistant to half shade and avoid muggy and damp. It has the habit of growing in cold season and dormant in high temperature in summer. As long as the regulation of water, fertilizer and temperature is appropriate, garlic seedlings can be harvested and put on the market about 20 days after planting. Remind the majority of friends: garlic seedlings like fertilizer, especially suitable for farmyard fertilizer and chemical fertilizer.

 

Platycodon grandiflorum seedling raising and transplanting are generally available from April to June. Early Platycodon grandiflorum seedlings affect the quality of seedlings, and late seedlings greatly affect transplanting. Generally, the seed amount of 667 M2 is 10 ~ 12 kg (15 kg in some experimental fields). In the middle stage, phosphorus and potassium fertilizer is mainly used to increase the fertilizer at the flowering stage, so as to prevent the growth from being affected by excessive nutrient consumption due to flowering and fruiting. After winter, people should re apply winter fertilizer and cultivate soil in combination with fertilization.

 

When the temperature drops to close to 0 ℃, move the 19cm plant pots to the light in the room, and cover the curtain at night to keep warm. It is advisable to keep 3 ℃ to 5 ℃ during overwintering. If it exceeds 16 ℃, it will germinate in advance and cause fallen leaves and buds. In the planting of flowers, water evaporation will be faster. If diseases and pests are found, they should be sprayed for control, otherwise there will be serious bud falling phenomenon. When plants cannot get water supply, they will bud first and then fall leaves.

 

The growth of Osmunda japonica needs an acidic environment, so we should choose the acidic soil with high organic matter content. The best waste slope is to have good performance of water and fertilizer conservation, and the water source conditions of the cultivation land are good.. Keep the soil moist after planting, and do a good job in field drainage in rainy season. Carefully collect the weeds in and around the countryside. There are few diseases and pests in the whole growth period of Osmunda, but comprehensive control is still needed.

 

Scrape as you dig to prevent the skin from drying and shrinking, and it is easier to peel. After the fresh roots are processed and dug out, clean the soil and reed head, scrape the cork with bamboo knife, wood edge and porcelain chip, wash and dry them in the sun or dry them. 0.3% potassium dihydrogen phosphate solution can be sprayed on the leaves for 2-3 times. Depending on the growth of seedlings, 15-20 kg of urea can be applied every 667 square meters from the group tree stage to the plant ridge closure in combination with irrigation.

 

At present, the cultivation area of black potato in China is still small. The price per kilogram is 6-8 yuan, which is 6-8 times that of ordinary potato. It is popular in the market and has considerable economic benefits. During the harvest period, in order to prevent the yield reduction caused by ponding and rotten roots in the 16cm plant pots, the drainage ditch should be done in time when it is hot and rainy in summer. Over dense plants grow thin and weak, and are easy to be damaged by diseases and insect pests. Over sparse plants have low yield.

 

It's better to plant dental cutting blocks in one or two seeds, which will be very high-yield. Seed potato cutting and germination before sowing can promote early emergence, increase field growth period and increase yield. Applying enough base fertilizer, black potato is a high-yield and fertilizer loving crop. Black potatoes can be used as both side dishes and special dishes. Generally, the yield per mu is 2000 kg ~ 2500 kg, which is about 15% higher than that of ordinary varieties.
