Cutting carnation in winter and spring
Carnation is generally propagated by cuttage, which is carried out in winter and spring and can be carried out from December to April of the following year. At this time, the lateral buds used as cuttings grow strongly and have the best quality. At the same time, cutting during this period can control the flowering of plants in the second year New Year's Day and the Spring Festival. First of all, the culture soil should be prepared, and the garden soil should be mixed with 30%-40% rice bran ash or sandy soil. after mixing evenly, it should be put into a basin or wooden box. The cuttings should be carried out in the greenhouse, and the cuttings should be selected from the mother plants with strong growth, neat flowering and thick nodes and short branches.

New varieties of Carnation with large Flowers
First, variety introduction: the Flower Institute of Yunnan Academy of Agricultural Sciences undertook the scientific and technological research project "breeding of New varieties of Carnation" of the Provincial Department of Science and Technology in the later period of the Ninth five-year Plan, and has bred a number of new varieties (strains) of cut carnation. Some of the new varieties have been tested by flower farmers on a small scale, showing good production suitability and marketability. Apply for 4 new variety rights of carnation to the Plant New Variety Protection Office of the Ministry of Agriculture. Among them, Yunhong No. 1 is compared with Masters, a foreign variety with the same red line and the largest planting area at present.

Occurrence and control of carnation virus disease in protected area
Symptom recognition carnation vein mottle disease carnation leaf vein mottle virus infects carnation, Chinese carnation and American carnation, all produce systematic mosaic, and old leaves often appear hidden phenomenon in winter. Discoloration spots appeared on the petals, especially in the varieties of large red flowers. Carnation latent virus disease Carnation generally shows no symptoms or mild mosaic symptoms after being infected by the virus. However, mosaic symptoms occurred when carnation latent virus and carnation vein mottle virus were co-infected. Carnation

Fungal Leaf spot of cut Carnation
Symptoms: a purple round spot between the diameter of 0.5~1.5cm, surrounded by a yellowish-green edge; then the middle of the spot becomes brownish gray and dry, and finally the spot expands, black spores appear, and the leaves begin to turn yellow and fall off. Reasons: watering from the upper part of the plant, poor ventilation, high humidity at night, excessive watering and fertilization after planting is also one of the causes of the disease. Control methods: keep the plant dry as far as possible, it is best to use drip irrigation, keep good ventilation. Use 1% Bordeaux solution or 75% chlorothalonil wettable powder 500 times

Cultivation techniques of deep pine and narrow row parallel sowing and dense planting of soybean
Soybean deep loosening and narrow row parallel sowing and dense planting is a new high-yield cultivation model of soybean after & ldquo; & rdquo; and & ldquo; & rdquo;. It synthesizes the advanced technologies such as deep loosening and rotary ploughing, keeps secret with fertilizer, increases yield with density, increases canopy area index, increases light energy interception rate, and realizes cost saving and efficiency increasing in soybean production. In the past two years, Luobei County has popularized and planted 16000 mu in United, Fengxiang, Zhaoxing and Taipinggou, with an average yield of 206kg per mu, an increase of 43% over the control.

What are the technical points of horizontal cropping, narrow row and close planting of soybean?
Technical points of flat cropping, narrow row and dense planting of soybean: first, seeds and treatment: variety selection according to local ecological types, suitable varieties according to local conditions. Second, seed quality: it is necessary to reach the seed classification standard of more than two improved varieties. Third, seed treatment: seed dressing agent is used to select seeds according to the types of diseases and insect pests and soil conditions. Fourth, rotation and ploughing and land preparation: rotation for more than 3 years, no stubble, no stubble, the first crop is mainly wheat crops. Deep loosening is mainly adopted in farming, with the combination of loosening and harrowing, in order to resist drought and preserve soil moisture. five

Mechanized high-yield cultivation techniques of soybean close planting
The comprehensive high-yield cultivation technology of soybean close planting mechanization is on the basis of soybean three-ridge cultivation technology, continuing to maintain deep loosening, layered deep fertilization, precision sowing, absorbing foreign experience in increasing production, such as narrow row close planting and semi-dwarf varieties, and combined with supporting machines and tools, a mechanized comprehensive high-yield cultivation technique is assembled, including flat sowing and small ridge dense planting techniques. First, technical advantages. 1. Reasonable close planting to increase output. The technical characteristics are reasonable close planting, uniform distribution of crops and increase of crop photosynthesis. Select semi-dwarf varieties with lodging resistance.

How to control the falling flowers and pods of soybean
First, reasonable topdressing. Usually, nitrogen fertilizer is applied once at the early flowering stage of soybean, which can reduce the rate of falling flowers and pods, prolong plant life, increase grain weight and increase yield. Generally, 150 kg of ammonium nitrate can be applied per hectare, or 120 kg of urea can be applied to 180 kg of urea, 0.5 kg of urea, 1.5 kg of superphosphate, 0.3 kg of potassium sulfate per mu, 30 g of borax, 50 kg of water, extracted and sprayed on the leaf surface, which is beneficial to protecting flowers and increasing pods and seeds.
