The original code of the Jimai 20 wheat variety is 955159
It was developed by the Crop Research Institute of the Shandong Academy of Agricultural Sciences through sexual hybridization using Lumai 14 as the female parent and Lu 884187 as the male parent, followed by systematic selection. From 2000 to 2002, this variety participated in the high-fertility Group B regional trial of wheat in Shandong Province, with a two-year average yield of 507.05 kg per mu, 0.78% lower than the control Lumai 14. From 2002 to 2003, it participated in the high-fertility group production trial of wheat in Shandong Province, with an average yield of 513.37 kg per mu, 8.69% higher than the control Lumai 14. It is suitable for Shandong

Symptom Identification and Control Methods of Rust Disease in Codonopsis pilosula
It damages the leaves. The diseased area on the underside of the leaf is slightly raised, forming the uredinium, which later ruptures and releases orange-yellow urediniospores. The disease is most severe from June to July. Control methods: (1) Clear away withered branches and fallen leaves in winter. (2) During the disease period, spray with a 200-fold dilution of 50% dinitro compound or a 400-fold dilution of 97% sodium dithiocarbamate, once every 7 days, for 2 to 3 consecutive applications.

Introduction to the New Codonopsis Variety 92-02
I. Variety Introduction: Codonopsis pilosula is one of the main medicinal herbs in Dingxi City, Gansu Province, with a planting area of about 18,700 hm2 over the years and a total output of more than 30,000 t, accounting for 40% of China's Codonopsis pilosula share. In 2001, Weiyuan County of Dingxi City was named "China's Hometown of Codonopsis pilosula" by the Organizing Committee of the Hometown of Specialty Products of the Chinese Association of Agricultural Science Societies, and the Codonopsis pilosula industry has become one of the important pillar industries of Dingxi City. However, the Codonopsis pilosula currently planted in fields is basically a mixture of multiple types, which has adversely affected yield and quality and severely restricts the sustainable development of the Codonopsis pilosula industry.

What are the control methods for rodent damage to codonopsis (Codonopsis pilosula)?
They begin to damage the seedlings when the seedlings emerge 5 cm above ground. Control methods: (1) Mix 1 part of 3% zinc phosphide with 95 parts of green vegetables, beans, rice, etc.; after mixing well, scatter the bait in the evening in places where rats frequently appear or at their burrows. (2) Mix 1 part of 0.5% bromadiolone evenly with 3 parts of flour, then add cut apple pieces, vegetables, and fried dough sticks (cut into 1 cm pieces) and mix them evenly to coat; this can be placed in the evening in places where rats are frequently active. Alternatively, use 2.5% phorate granules at 1500 g per 667 sq m mixed with 10 kg of fine soil and scatter it along the edges of beds and ridges to drive rats away; be careful not to scatter it on the seedlings.

How to grow Codonopsis pilosula? A detailed explanation of the key points of Codonopsis pilosula cultivation techniques
1. Site selection and land preparation For the seedling bed, it is best to choose a sandy loam or humus loam close to a water source, with loose, fertile soil and good drainage, and a shady slope facing away from the sun; for the planting site, a gently sloping field or terraced field with high, dry terrain and good drainage should be chosen, and virgin wasteland as well as flat land are both acceptable, but the soil layer must be deep, relatively fertile, well structured, and easy to cultivate. After the soil is selected, in the winter of the previous year clear the shrubs and weeds from the virgin wasteland, burn them to ash for fertilizer, then deep plow the soil 30 cm, level and harrow it fine, and make raised beds 1.3 m wide

Soil preparation methods and key technical points for Codonopsis pilosula cultivation
Both spring plowing and autumn plowing are acceptable, but autumn plowing is preferable. Before plowing, spread 30,000-50,000 kg of decomposed farmyard manure or compost per hectare, then plow to a depth of 25-30 cm, harrow fine and level. Codonopsis pilosula (poor man's ginseng) is suited to bed cultivation, with a bed width of 120 cm; on high, dry terrain flat beds can be made, while on lower terrain raised beds of 10-15 cm can be made. In some places ridge cultivation is practiced; to increase the number of plants per unit area, make small ridges of 50 cm, or make wide ridges of 60 cm with double-row planting.

How to Choose Land for Codonopsis Planting? These Methods Must Be Mastered
Codonopsis is a deep-rooted plant, and mature plants prefer light, so it is best to choose deep, fertile, sunny sandy loam for cultivation. Low-lying, waterlogged, and heavy clay soil is not suitable for cultivation; water accumulation in the soil easily causes root rot, poor aboveground plant growth, and low yield with poor quality. Slightly acidic to neutral soil with a pH of 6.5-7 is preferable. Legume and grass family crops are best as the previous crop; vegetable crops as the previous crop are prone to disease and should not be chosen. Continuous cropping is prohibited, and generally 3-4 years should pass before replanting.
