Small method of high yield of bean planting

Beans are also called cowpeas, and their habits and cultivation techniques are similar to kidney beans. The growth characteristics of beans are rhizobia can fix nitrogen, but they are young pods and young beans for the harvest, so nitrogen supply is indispensable, especially in the early stage. N: P: K =1:0. 6：1。3. Trace element Mo can promote the vigorous development of nodules, beans are also sensitive to trace elements such as boron and zinc, so on the basis of reasonable application of N, P and K fertilizers, spraying boron, molybdenum and zinc fertilizers can improve the pod setting rate of beans, improve seed fullness and increase yield.

Because root system has rhizobium to belong to aerophilic sex, this also is kidney bean ability short-term soil drought, one of causes that bear moisture badly.

1. Soil preparation and sowing

It is advisable to select fields that have not been planted with beans, and to disinfect continuous cropping fields, because continuous cropping fields are prone to root rot and blight, causing beans to wither and die, which is difficult to control.

1. Disinfection.

① mu with quicklime 60 - 80 kg retting field, 7 - 10 days after drainage, sun whitening;

② Before planting, use potassium permanganate 500 times solution, or bean mushroom fear (also available hymexiline or Junzhenqing No.2)+ Belin (plus iodine) 500 times solution to irrigate the soil more than 3 cm deep.

2. Select ridges according to soil fertility. The ridge surface is about 40cm wide and 30cm high. 10 cm deep furrows are opened on the ridge surface, and 1000 kg decomposed manure water is used to drench the furrows per mu. sun-whitening, loosen soil, selecting suitable variety, soaking seeds in water after sun-drying for 4 hours, dressing seeds with chlorothalonil raw powder, using 25 grams of powder for every 500 grams of seeds, sowing in small ditches, planting in single row, sowing two seeds every 20 cm, covering with soil miscellaneous fertilizer or burning soil after sowing, and watering.

II. Seedling management

After sowing for two days, according to the dry and wet conditions of the ridge surface, lightly sprinkle water to ensure the water required for seedling emergence. After 5 - 6 days, when the bean seedlings have two leaves and one heart, sprinkle them with 800 times of Jinggangmycin and 750 kg of liquid medicine per mu to prevent and control root rot, epidemic diseases and other diseases.

Thinning seedlings in time to ensure that every 20 cm a plant. Be careful not to touch the plant when applying the medicine.

According to the bean seedling growth appropriate fertilization, mu with urea 3 - 5 kg, plus the same amount of potassium fertilizer mixed with water 1000 - 1500 kg, after the application of thin water. The control of bean thrips is the focus of seedling stage, bean thrips damage young tender heart tip is also common without shoot out, only two leaves, commonly known as "blind heart".

To control bean thrips, 600 times of ifosfon plus 600 times of pyrifos, or 1500 times of abamectin plus 1500 times of imidacloprid, or 500 times of 5% Regent, spray once every 6 days, spray 1 - 2 times of Yunda 120 at seedling stage.

III. Management of vine growing period

Bean seedlings have vines out, to carry out large-scale soil cultivation, joint fertilization, mu with phosphorus fertilizer 30 kg plus urea 10 kg, evenly applied to both sides of the ridge, with furrow soil to cover fertilizer and weeds, pay attention to fertilizer and soil do not contact bean stems. Conditions can be mu manure 2000 kg, in the ridge edge cultivated soil.

After cultivating soil, use thiamine mixture to drench once, and use copper sulfate 1kg, carbamine 2kg and water 1000kg per mu.

At the same time, the vine is placed on the shelf, usually in a herringbone frame.

Seedling prosperous long, can adopt cone-shaped frame, namely every 40 centimeters, insert into equilateral triangle with three bamboo, tie into cone with rope from ridge surface, horizontal bamboo on the upper frame, in order to facilitate operation should control the height of scaffolding within 2 meters. Conical frame can increase production more than 10% than herringbone frame.

Control moisture, sunny day every 3 days irrigation run horse water 1 time, wet ridge surface at the same time, rainy day pay attention to drainage.

The pests and diseases in the vine growing period are mainly rust, powdery mildew, bean thrips and bean borers. Trimefon (800 - 500 times) can be used to add 500 times of aminothion and 800 times of Anlubao, or 600 times of Xiansheng and 600 times of omnipotent powder. Pay attention to the concentration of trimefon from weak to thick (800 - 500 times). Spray once every 7 days and add 120 times of Yunda every 14 days.

IV. Harvest management

About 60 days after sowing, the plants enter reproductive growth, and the harvest period emerges. Fertilize once every 7 days. Each time, use 10kg compound fertilizer plus 5kg urea per mu, mix with 100kg manure for 3 days, add 1500kg water and apply it to the ridge surface, sprinkle thin water after application, or apply it in the ridge edge hole. Use 20kg compound fertilizer plus 10kg potassium fertilizer plus 10kg urea per mu. Apply it at an interval of 35cm at the ridge edge. Apply it on one side of each ridge. After 10 days, apply the same amount of fertilizer on the other side.

The holes should be watered before application, do not sprinkle water on the ridge surface within two days after application, and do not fertilize on rainy days. Harvest period should maintain furrow 1 - 2 cm water.

The following chemicals can be selected for disease and pest control to prevent and control spot blight and epidemic disease: 75% chlorothalonil 600 times and 70% mancozeb 600 times; rust and powdery mildew: 50% colloidal sulfur 300 times, spraying 1000 kg of liquid medicine per mu, but the premise is that no disease occurs, and prevention is better than treatment.

Pests are mainly bean borers, which can be used:

1. Vegetable Xi 1000 times and imidacloprid 1500 times;

② Abamectin 1500 times plus Anlubao 600 times;

③ Bacillus thuringiensis 1000 times more than small insect enemy 800 times.

Do not mix the above three agents with fungicides.

Because the bean moth control is very difficult, so spraying time should be every 3 - 4 days spray 1 time, in the morning before 10 o 'clock bean flower open spray effect is better.

Add 120 spray clouds every 7 days. Harvesting in the morning before the fog is wet is advisable.
