Broccoli is also known as broccoli and green cauliflower. It is a Brassica vegetable belonging to the family Brassica. It has bright green color, crisp stems, fragrant flavor, rich nutrition, and anti-cancer effects. Broccoli is a fast-growing fresh and processed export vegetable in recent years, especially non-pollution broccoli, with good economic benefits. In the following, we will give technical advice on how to grow good broccoli in the spring with low price for the vegetable growers by combining the Ginba base soil starter and its fertilizer starter.
1. Broccoli spring planting preparation
In order to save costs, improve production efficiency. The seedling substrate soil and the organic fertilizer can be obtained by using a Tribolium substrate soil and a fertilizer starter. The use of starter to produce raw materials for vegetable production will save a lot of money for vegetable farmers. For example, when a substrate soil is used to produce vegetable seedlings, only one kilogram of starter can be used to complete nearly five tons of raw materials. Fermentation. In addition, the raw materials for fermentation can be easily obtained. The farmers can make full use of the leftover materials (such as wheat straw and corn stalks) and the organic waste in the fields to complete the production of production materials. It also includes the production of farm organic fertilizer, which not only saves production costs, but also reduces the use of chemical fertilizers and ensures that the pollution-free degree of lettuce is improved.

2. Broccoli sowing and planting in spring
The sowing date is determined according to different places. For example, the spring, broccoli cultivating plains in Jiangsu and Zhejiang are sown in the period from January to January. The selection of the variety of the harmful lettuce is very important. It must be selected according to the local climate, market demand and planting time. Disease-resistant, stress-resistant, high-yield and adaptable varieties. In addition, in order to cater to the needs of customers, we must also choose good quality and good plant type.
Seedlings are planted on the above-mentioned cultivation medium and evenly sowed, sprinkled with a small amount of bactericide such as carbendazim or chlorothalonil (prevention of damping-off), covered with water (with no seed as the cover), and placed on a small shed in a greenhouse Inside and cover with plastic film and non-woven fabric, at 20-25 degrees Celsius, 3-6 days after the seeds germinate the top soil, remove the film, if the seeds are exposed, and then cover with some matrix, dry matrix, pouring a small amount of water After 9 days, the cotyledon can be transplanted. The transplanted seedlings were required to contain well-prepared culture soil (according to the cultivation medium: sieving compost: sifted soil ratio = 3:3:4). After one week, the water was poured and one hole was transplanted. After the seedlings are transplanted, a small amount of water is poured and placed on the nursery sheds for detailed cultivation and management.
3. Broccoli Spring Planting Pest Control
The broccoli disease mainly includes downy mildew, which is easy to occur. Therefore, spraying chlorothalonil once every day after emergence can prevent and treat it. There are not many pests of broccoli in spring, but prevention work should be done. Before planting, we must clean pastoral and ditch-edge weeds to eliminate overwintering pests. Pre-control locust use 1000 times "one-time net" liquid; control diamondback moth, cabbage caterpillar and beet armyworm and other extermination 2000 times liquid. One pesticide can only be sprayed once, and another pesticide must be replaced to prevent pests from developing resistance. It is forbidden to spray pesticides to prevent poisoning after squaring.
4. Broccoli spring harvest principle
When the flower ball is tight, solid, dark green, and the flower grains are small, the individual flower balls can be harvested when their weight reaches the harvesting standard. The relatively high temperatures in April-May require harvesting before 7 o'clock in the morning, and they cannot be harvested after 10 o'clock in the sunny day, and are not harvested on rainy days, and are generally harvested once a day.
