Tianyuan No. 4-Ziyunying

"Tianyuan No. 4" Ziyunying, also known as safflower. It is a perennial herbaceous plant belonging to the leguminous Astragalus family. It is mostly interplanted in late rice fields in autumn as a base fertilizer for early rice. It can not only improve fertility, improve soil and protect the ecological environment of farmland, but also increase rice yield and improve quality. High, rich in egg quality, and rich in a variety of minerals and vitamins, the stems and leaves are fresh and juicy, and the palatability is good. It is a good green material.

Habit characteristics

The taproot of Yunying is relatively fat, generally 40-50 cm deep into the soil. Nodules can be formed on the taproot, lateral roots and fine roots on the ground. The plant height is generally 80-120 cm. Thousand grains weigh 3-3.5 grams.

Ziyunying likes a cool climate, and its optimum growth temperature is 15-20°C. When the seedling stage is below 8°C, the growth rate is slow; after the beginning of spring, the growth rate is obviously accelerated. Although milk vetch has strong moisture resistance, waterlogging in the field is very detrimental to its growth. In severe cases, it may even die. Therefore, soil that is easy to drain should be selected. Lax requirements on scholars.

How to use

(1) "Tianyuan 4" Ziyun UK has a strong nitrogen capacity and is a good green manure. It can fix 75-120 kg of nitrogen per day during the full blooming period. Generally, the green retting field should be pressed about 15 days before the rice throwing (transplanting) seedlings, and it is more suitable to turn the plow in the blooming period, when the yield and nutrients reach the highest peak. When pressing the green field, it is usually 1000-1500 kilometers per acre. It is best to cut the plants into two or three sections, spread them on the field and let the stems and leaves soften, then remove 15-25 kg of lime, and then plow them. , Put the shallow water back into the field, and rake it before throwing (planting) the seedlings.

(2) Milk vetch is also a good material for all kinds of livestock. The dry matter at flowering stage contains 25.8% crude protein and the digestibility is more than 70%. The general methods of feeding pigs with milk vetch are as follows: ①Fresh feeding: It is better to mix 1 catty of concentrated feed with 6-7 cats of fresh milk vetch; Like to eat, generally it can be mixed with about 50%. The advantages of silage are long storage time, large storage volume, low cost, less nutrient loss, and good taste. Although ruminants such as cattle, sheep, and horses can use Ziyunying as material, they do not claim to eat too much, so as not to cause abdominal distension.

(3) Astragalus vulgaris has a strong sun-rich effect, and can develop Fu-sun tea and Fu-sun dried vegetables. It is also the main nectar plant with high medicinal value.

(4) Milk vetch has a long flowering period. It blooms from March to May. The flowers range from pink to purplish red. It can be embellished, scattered, and matched with shrubs, which can enrich the landscape of garden plants.

Suitable mowing period

When "Tianlu No. 4" Ziyunying is used as a green manure, it is more suitable to turn the plow in the full bloom period; when it is used as feed, it is better to cut it in the first flowering period.

Training technical points

"Tianyuan 4" Ziyunying's broadcast period is from early September to mid-October, and the seeding amount is generally 2-5 kg ​​per window. The yield will increase with the increase of the seeding amount, but if it is too high, there will be no Effect. 4-5 kg ​​is suitable for the north and 2-3 kg for the south. Rice bottom interplanting is mainly spread, and the spreading should be even. Wide-spread sowing or dense cluster sowing can also be used in dry land, low-yield fields or when the seeding amount is small. When the milk vetch grows rapidly after spring, applying 3-5 kg ​​of urea per mu can significantly increase its yield. In addition, in areas where conditions permit, the use of organic fertilizer as a base fertilizer has a good effect on the growth of milk vetch seedlings, the development of nodules and the whole seedlings. Generally, the harvest time should be mastered in the blooming period, and the fresh grass yield can reach 3000-5000 kg per mu.
